Otherwise we cannot use generic OF_DEV_AUXDATA match without listing
all the compatibles separately for OF_DEV_AUXDATA. Let's also update the
binding accordingly.
Let's also fix omap4.dtsi to use "ti,sysc-omap4-sr" compatible as we
have documented in the binding. This was not noticed earlier as we're
still probing SmartReflex driver with platform data.

The at24 driver allows to register I2C EEPROM chips using different vendor

when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings

So add this generic fallback to the device node compatible string to make

This device tree will break existing kernels that do not have the clk
patches applied (no clocksource, as we don't know the speed of the APB
clock. You can boot if you pass a lpj value on the command line, but
won't have a uart).
Older device trees running with the newer kernel will function as well
as pre-4.16 kernels. That is, that some IP blocks (i2c, pwm/tach, adc)
will not work as the kernel lacks reset controller and clock enabling.
This is being changed as existing device trees use fixed-clocks in order
to boot without a clk driver. The newly added clk driver provides proper
clock support, including gating, so we move the device trees over to
properly request clocks.
The SCU compatible string is updated as the g4-scu string made it into
the tree before we decided on aspeed,astX000-<ip> as the format for the
strings. The old string will be removed from the bindings in a future
patch.

On arm, PCI_REASSIGN_ALL_RSRC is used only in pcibios_assign_all_busses(),
which helps decide whether to reconfigure bridge bus numbers. It has
nothing to do with BAR assignments. On arm64 and powerpc,
pcibios_assign_all_busses() tests PCI_REASSIGN_ALL_BUS, which makes more
sense.
Align arm with arm64 and powerpc, so they all use PCI_REASSIGN_ALL_BUS for
pcibios_assign_all_busses().
Remove PCI_REASSIGN_ALL_RSRC from the generic, Tegra, Versatile, and
R-Car drivers. These drivers are used only on arm or arm64, where
PCI_REASSIGN_ALL_RSRC is not used after this change, so removing it
should have no effect.

====================
pull-request: bpf-next 2017-12-18
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Allow arbitrary function calls from one BPF function to another BPF function.
As of today when writing BPF programs, __always_inline had to be used in
the BPF C programs for all functions, unnecessarily causing LLVM to inflate
code size. Handle this more naturally with support for BPF to BPF calls
such that this __always_inline restriction can be overcome. As a result,
it allows for better optimized code and finally enables to introduce core
BPF libraries in the future that can be reused out of different projects.
x86 and arm64 JIT support was added as well, from Alexei.
2) Add infrastructure for tagging functions as error injectable and allow for
BPF to return arbitrary error values when BPF is attached via kprobes on
those. This way of injecting errors generically eases testing and debugging
without having to recompile or restart the kernel. Tags for opting-in for
this facility are added with BPF_ALLOW_ERROR_INJECTION(), from Josef.
3) For BPF offload via nfp JIT, add support for bpf_xdp_adjust_head() helper
call for XDP programs. First part of this work adds handling of BPF
capabilities included in the firmware, and the later patches add support
to the nfp verifier part and JIT as well as some small optimizations,
from Jakub.
4) The bpftool now also gets support for basic cgroup BPF operations such
as attaching, detaching and listing current BPF programs. As a requirement
for the attach part, bpftool can now also load object files through
'bpftool prog load'. This reuses libbpf which we have in the kernel tree
as well. bpftool-cgroup man page is added along with it, from Roman.
5) Back then commit e87c6bc385 ("bpf: permit multiple bpf attachments for
a single perf event") added support for attaching multiple BPF programs
to a single perf event. Given they are configured through perf's ioctl()
interface, the interface has been extended with a PERF_EVENT_IOC_QUERY_BPF
command in this work in order to return an array of one or multiple BPF
prog ids that are currently attached, from Yonghong.
6) Various minor fixes and cleanups to the bpftool's Makefile as well
as a new 'uninstall' and 'doc-uninstall' target for removing bpftool
itself or prior installed documentation related to it, from Quentin.
7) Add CONFIG_CGROUP_BPF=y to the BPF kernel selftest config file which is
required for the test_dev_cgroup test case to run, from Naresh.
8) Fix reporting of XDP prog_flags for nfp driver, from Jakub.
9) Fix libbpf's exit code from the Makefile when libelf was not found in
the system, also from Jakub.

The Broadcom Brahma-B15 readahead cache needs to be disabled,
respectively re-enable during a CPU hotplug. In case we were not to do,
CPU hotplug would occasionally fail with random crashes when a given CPU
exits the coherency domain while the RAC is still enabled, as it would
get stale data from the RAC.
In order to avoid adding any specific B15 readahead-cache awareness to
arch/arm/mach-bcm/hotplug-brcmstb.c we use a CPU hotplug state machine
which allows us to catch CPU hotplug events and disable/flush enable the
RAC accordingly.

This patch adds support for the Broadcom Brahma-B15 CPU readahead cache
controller. This cache controller sits between the L2 and the memory bus
and its purpose is to provide a friendler burst size towards the DDR
interface than the native cache line size.
The readahead cache is mostly transparent, except for
flush_kern_cache_all, which is precisely what we are overriding here.
The readahead cache only intercepts reads, and does invalidate on
writes (IOW), as such, some data can remain stale in any of its buffers, such
that we need to flush it, which is an operation that needs to happen in
a particular order:
- disable the readahead cache
- flush it
- call the appropriate cache-v7.S function
- re-enable
This patch tries to minimize the impact to the cache-v7.S file by only
providing a stub in case CONFIG_CACHE_B15_RAC is enabled (default for
ARCH_BRCMSTB since it is the current user).

Avoid adding kprobes to any of the kernel entry/exit or startup

not conform to the standard C conventions, which means that the
expectations of the kprobes code is not forfilled.
Placing kprobes at some of these locations results in the kernel trying
to return to userspace addresses while retaining the CPU in kernel mode.

The GNU assembler has implemented the "unified syntax" parsing since
2005. This "unified" syntax is required when the kernel is built in
Thumb2 mode. However the "unified" syntax is a mixed bag of features,
including not requiring a `#' prefix with immediate operands. This leads
to situations where some code builds just fine in Thumb2 mode and fails
to build in ARM mode if that prefix is missing. This behavior
discrepancy makes build tests less valuable, forcing both ARM and Thumb2
builds for proper coverage.
Let's "fix" this issue by always using the "unified" syntax for both ARM
and Thumb2 mode. Given that the documented minimum binutils version that
properly builds the kernel is version 2.20 released in 2010, we can
assume that any toolchain capable of building the latest kernel is also
"unified syntax" capable.
Whith this, a bunch of macros used to mask some differences between both
syntaxes can be removed, with the side effect of making LTO easier.

The linker can sometimes add additional sections to the zImage ELF file

causes appended DT blobs to fail.
Verify that the zImage binary is the expected size, and fail the build

The A83T has 3 I2C controllers under the standard bus. There is one
more in the R_ block section. The pin functions for the 3 controllers
are on PH 0~6. I2C2 can also be used on pins PE14 and PE15, but these
pins can also mux the CSI (camera sensor interface) controller's
embedded I2C controller. The latter seems to be preferred in the
reference designs for I2C camera sensor access, freeing I2C2 for other
uses.
This patch adds device nodes for the three standard I2C controllers,
as well as pinmux settings for the PH pins. For I2C0 and I2C1, since
they only have one possible setting, just set them by default.

EXYNOS_IOMMU is disabled in exynos_defconfig since it was known to cause
boot failures on Exynos Chromebooks. The recommendation was for IOMMU to
be enabled manually on systems as needed.
A recent exynos_drm change added a warning message when EXYNOS_IOMMU is
disabled. It is necessary to enable it to avoid the warning messages.
A few initial tests have shown that enabling EXYNOS_IOMMU might be safe
on Exynos Chrome-books.
Due to some other changes in the order of operations during boot
process, power domains are initialized very early and because of the
temporary lack of devices (which are not yet added to the system), are
turned off.
This practically stops FIMD for scanning framebuffer very early during
boot, before IOMMU gets initialized and "solves" the issue, which was
the reason to disable Exynos IOMMU by default on Exynos Snow Chromebooks.

ARM SoC fixes for this merge window:
- A revert of all SCPI changes from the 4.15 merge window. They had
regressions on the Amlogic platforms, and the submaintainer isn't
around to fix these bugs due to vacation, etc. So we agreed to revert
and revisit in next release cycle.
- A series fixing a number of bugs for ARM CCN interconnect, around
module unload, smp_processor_id() in preemptable context, and fixing
some memory allocation failure checks.
- A handful of devicetree fixes for different platforms, fixing
warnings and errors that were previously ignored by the compiler.
- The usual set of mostly minor fixes for different platforms.

The w1 master driver includes a complete open drain emulation
reimplementation among other things.
This converts the driver and all board files using it to use
GPIO descriptors associated with the device to look up the
GPIO wire, as well ass the optional pull-up GPIO line.
When probed from the device tree, the driver will just pick
descriptors and use them right off. For the two board files
in the kernel, we add descriptor lookups so we do not need
to keep any old platform data handling around for the GPIO
lines.
As the platform data is also a state container for this driver,
we augment it to contain the GPIO descriptors.
w1_gpio_write_bit_dir() and w1_gpio_write_bit_val() are gone
since this pair was a reimplementation of open drain emulation
which is now handled by gpiolib.
The special "linux,open-drain" flag is a bit of mishap here:
it has the same semantic as the same flags in I2C: it means
that something in the platform is setting up the line as
open drain behind our back. We handle this the same way as
in I2C.
To drive the pull-up, we need to bypass open drain emulation
in gpiolib for the line, and this is done by driving it high
using gpiod_set_raw_value() which has been augmented to have
the semantic of overriding the open drain emulation.
We also augment the documentation to reflect the way to pass
GPIO descriptors from the machine.

Commit 0515e5999a ("bpf: introduce BPF_PROG_TYPE_PERF_EVENT
program type") introduced the bpf_perf_event_data structure which
exports the pt_regs structure. This is OK for multiple architectures
but fail for s390 and arm64 which do not export pt_regs. Programs
using them, for example, the bpf selftest fail to compile on these
architectures.
For s390, exporting the pt_regs is not an option because s390 wants
to allow changes to it. For arm64, there is a user_pt_regs structure
that covers parts of the pt_regs structure for use by user space.
To solve the broken uapi for s390 and arm64, introduce an abstract
type for pt_regs and add an asm/bpf_perf_event.h file that concretes
the type. An asm-generic header file covers the architectures that
export pt_regs today.
The arch-specific enablement for s390 and arm64 follows in separate
commits.

The Libre Computer Board ALL-H3-CC from Libre Technology is a Raspberry
Pi B+ form factor single board computer based on the Allwinner H3 SoC.
The board has 1GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes
and connectors are in the exact same position as on the Raspberry Pi B+.
Raspberry Pi B+ like peripherals supported on this board include:
- Power input through micro-USB connector (without USB OTG)
- Native 100 Mbps ethernet using the internal PHY, as opposed to
USB-based on the RPi
- 4x USB 2.0 host ports, directly connected to the SoC, as opposed to
being connected through a USB 2.0 hub on the RPi
- TV and audio output on a 3.5mm TRRS jack
- HDMI output
- Micro-SD card slot
- Standard RPi B+ GPIO header, with the standard peripherals routed to
the same pins.
* 5V, 3.3V power, and ground
* I2C0 on the H3 is routed to I2C1 pins on the RPi header
* I2C1 on the H3 is routed to I2C0 pins on the RPi header
* UART1 on the H3 is routed to UART0 pins on the RPi header
* SPI0 on the H3 is routed to SPI0 pins on the RPi header,
with GPIO pin PA17 replacing the missing Chip Select 1
* I2S1 on the H3 is routed to PCM pins on the RPi header
- Additional peripherals from the H3 are available on different pins.
These include I2S0, JTAG, PWM1, SPDIF, SPI1, and UART3
In addition, there are a number of new features:
- Console UART header
- Consumer IR receiver
- Camera interface (not compatible with RPi)
- Onboard microphone
- eMMC expansion module port
- Heatsink mounting holes
- Power button
The power button requires corresponding software for the embedded
coprocessor to properly function.
This patch adds a dts file for this board that enables all "onboard"
peripherals currently supported. This means no display or camera
support.

Fixes for omaps for v4.15-rc cycle with two fixes for hangs with the
rest being compiler warning fixes and fixes for power states and devices
on various boards:
- Fix smatch issue introduced by recent omap device changes for legacy
resources
- Fix SRAM virt to phys related boot hang affecting n900 and other omap3 hs
devices found by pending CMA changes. While it seems that we have not hit
this in other use cases, let's fix it to avoid a nasty and hard to find
suprise as right now there is just luck keeping the SRAM virtual address
to physical address translation working with the 0xffff high_mask.
- Fix am335x reading of domain state registers that only exist for the
PM_CEFUSE domain and produce wrong results for other domains
- Fix missing setting for error code for omap device if allocation fails
- Fix missing modules_offs for omap3 MMC3 affecting n9/n950
- Fix cm_split_idlest() reading reserved registers showing wrong
idlestatus
- Fixes to correct #phy-cells property for compiler warnings that
recently started happening
- Add a missing OHCI remote-wakeup-connected property that I was supposed
to merge after the ohci-omap3 to ohci-platform changes but somehow managed
to drop. I only noticed this was missing while debugging the OHCI/EHCI GPS
and modem hang
- Fix a system hang with GPS or modem connected to the OHCI/EHCI bus that
typically happened within 20 - 40 minutes on an idle system. This turned
out to be an issue caused by using the parent interrupt controller directly
with the WUGEN + GIC stacked interrupt controller domains
- Fixes for logicpd-somlv GPMC for Ethernet and NAND that clearly
have been broken since we changed GPMC to use the interrupt controller
binding for some pins. And fix the wrong pin muxing for WLAN while at it
- Fixes for am437x interrupt and dma properties to fix compiler warnings

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

The flexcan driver has been modified to check for big-endian dts
property for be read/write to flexcan registers/mb.
An exception to this rule is powerpc P1010RDB, which is always
big-endian, even if big-endian is not present in dts. This is
checked using p1010-flexcan compatible in dts.
Therefore, remove p1010-flexcan compatible from imx series dts,
as their flexcan core is little endian.

commit 200a575b68 ("ARM: dts: meson: organize devices in their corresponding busses")
organized all peripherals in busses so that the base register offset of
the bus doesn't have to be included in all child-nodes anymore.
The GPIO interrupt controller however specifies the register offset
without subtracting the "cbus" base address. This leads to a problem
where of_iomap inside the irq-meson-gpio driver fails because it
actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880
for the GPIO interrupt controller). Fix this by using 0x9880 as register
offset.

In response to compile breakage introduced by a series that added the
pud_write helper to x86, Stephen notes:
did you consider using the other paradigm:
In arch include files:
#define pud_write pud_write
static inline int pud_write(pud_t pud)
.....
Then in include/asm-generic/pgtable.h:
#ifndef pud_write
tatic inline int pud_write(pud_t pud)
{
....
}
#endif
If you had, then the powerpc code would have worked ... ;-) and many
of the other interfaces in include/asm-generic/pgtable.h are
protected that way ...
Given that some architecture already define pmd_write() as a macro, it's
a net reduction to drop the definition of __HAVE_ARCH_PMD_WRITE.

There's been a reproducable USB OHCI/EHCI cpuidle related hang on omap4
for a while that happens after about 20 - 40 minutes on an idle system
with some data feeding device being connected, like a USB GPS device or
a cellular modem.
This issue happens in cpuidle states C2 and C3 and does not happen if
cpuidle is limited to C1 state only. The symptoms are that the whole
system hangs and never wakes up from idle, and if a watchdog is
configured the system reboots after a while.
Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC
interrupt controller directly as a parent instead of the WUGEN. We
need to pass the interrupts through WUGEN to GIC to provide the wakeup
events for the processor.
Let's fix the issue by removing the gic interrupt-parent and use the
default interrupt-parent wakeupgen instead. Note that omap5.dtsi had
this already fixes earlier by commit 7136d457f3 ("ARM: omap: convert

With the CMA changes from Joonsoo Kim <iamjoonsoo.kim@lge.com>, it
was noticed that n900 stopped booting. After investigating it turned
out that n900 save_secure_ram_context does some whacky virtual to
physical address translation for the SRAM data address.
As we now only have minimal parts of omap3 idle code copied to SRAM,
running save_secure_ram_context() in SRAM is not needed. It only gets
called on PM init. And it seems there's no need to ever call this from
SRAM idle code.
So let's just keep save_secure_ram_context() in DDR, and pass it the
physical address of the parameters. We can do everything else in
omap-secure.c like we already do for other secure code.
And since we don't have any documentation, I still have no clue what
the values for 0, 1 and 1 for the parameters might be. If somebody has
figured it out, please do send a patch to add some comments.

found)

Detect if we are returning to usermode via the normal kernel exit paths
but the saved PSR value indicates that we are in kernel mode. This
could occur due to corrupted stack state, which has been observed with
"ftracetest".

This mechanically converts all remaining cases of ancient open-coded timer
setup with the old setup_timer() API, which is the first step in timer
conversions. This has no behavioral changes, since it ultimately just
changes the order of assignment to fields of struct timer_list when
finding variations of:
init_timer(&t);
f.function = timer_callback;
t.data = timer_callback_arg;
to be converted into:
setup_timer(&t, timer_callback, timer_callback_arg);
The conversion is done with the following Coccinelle script, which
is an improved version of scripts/cocci/api/setup_timer.cocci, in the
following ways:
- assignments-before-init_timer() cases
- limit the .data case removal to the specific struct timer_list instance
- handling calls by dereference (timer->field vs timer.field)

This changes all DEFINE_TIMER() callbacks to use a struct timer_list
pointer instead of unsigned long. Since the data argument has already been
removed, none of these callbacks are using their argument currently, so
this renames the argument to "unused".

Currently, for ARM kernels with CONFIG_ARM_LPAE and
CONFIG_STRICT_KERNEL_RWX enabled, the 2MiB pages mapping the
kernel code and rodata are writable. They are marked read-only in
a software bit (L_PMD_SECT_RDONLY) but the hardware read-only bit
is not set (PMD_SECT_AP2).
For user mappings, the logic that propagates the software bit
to the hardware bit is in set_pmd_at(); but for the kernel,
section_update() writes the PMDs directly, skipping this logic.
The fix is to set PMD_SECT_AP2 for read-only sections in
section_update(), at the same time as L_PMD_SECT_RDONLY.

When CONFIG_ARM_LPAE is set, the PMD dump relies on the software
read-only bit to determine whether a page is writable. This
concealed a bug which left the kernel text section writable
(AP2=0) while marked read-only in the software bit.
In a kernel with the AP2 bug, the dump looks like this:
---[ Kernel Mapping ]---
0xc0000000-0xc0200000 2M RW NX SHD
0xc0200000-0xc0600000 4M ro x SHD
0xc0600000-0xc0800000 2M ro NX SHD
0xc0800000-0xc4800000 64M RW NX SHD
The fix is to check that the software and hardware bits are both
set before displaying "ro". The dump then shows the true perms:
---[ Kernel Mapping ]---
0xc0000000-0xc0200000 2M RW NX SHD
0xc0200000-0xc0600000 4M RW x SHD

Make the decompressor debug output user selectable, otherwise merely
enabling DEBUG_LL causes the decompressor to become board specific,
thereby preventing a multi-platform kernel from booting. Enabling
DEBUG_LL doesn't cause the kernel itself to become platform specific
unless EARLY_PRINTK is enabled, or one of the debugging routines is
added in a path that results in it being called.

One of the most remarkable improvements in this cycle is, Kbuild is
now able to cache the result of shell commands. Some variables are
expensive to compute, for example, $(call cc-option,...) invokes the
compiler. It is not efficient to redo this computation every time,
even when we are not actually building anything. Kbuild creates a
hidden file ".cache.mk" that contains invoked shell commands and
their results. The speed-up should be noticeable.
Summary:
- Fix arch build issues (hexagon, sh)
- Clean up various Makefiles and scripts
- Fix wrong usage of {CFLAGS,LDFLAGS}_MODULE in arch Makefiles
- Cache variables that are expensive to compute
- Improve cc-ldopton and ld-option for Clang
- Optimize output directory creation

We add device tree files for a couple of additional SoCs in various areas:
Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
As usual, lots of new boards get added based on those and other SoCs:
- Actions S500 based CubieBoard6 single-board computer
- Amlogic Meson-AXG A113D based development board
- Amlogic S912 based Khadas VIM2 single-board computer
- Amlogic S912 based Tronsmart Vega S96 set-top-box
- Allwinner H5 based NanoPi NEO Plus2 single-board computer
- Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
- Allwinner A83T based TBS A711 Tablet
- Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
- Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
wireless access points and routers
- NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
- NXP i.MX53 based GE Healthcare PPD biometric monitor
- NXP i.MX6 based Pistachio single-board computer
- NXP i.MX6 based Vining-2000 automotive diagnostic interface
- NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
- Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
- Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet
- Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA
- Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board
- Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards
- Renasas r8a7745 based iWave G22D-SODIMM SoM
- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic
and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues that
the latest version of 'dtc' now warns about. Unfortunately there is still
a lot left to do.
A rework of the ARM foundation model introduced several new files
for common variations of the model.

Pull ARM device-tree updates from Arnd Bergmann:
"We add device tree files for a couple of additional SoCs in various
areas:
Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for
networking, Amlogic A113D for audio, and Renesas R-Car V3M for
automotive.
As usual, lots of new boards get added based on those and other SoCs:
- Actions S500 based CubieBoard6 single-board computer
- Amlogic Meson-AXG A113D based development board
- Amlogic S912 based Khadas VIM2 single-board computer
- Amlogic S912 based Tronsmart Vega S96 set-top-box

- Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
- Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet
- Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA
- Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board
- Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards
- Renasas r8a7745 based iWave G22D-SODIMM SoM
- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX,
Amlogic and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues
that the latest version of 'dtc' now warns about. Unfortunately there
is still a lot left to do.
A rework of the ARM foundation model introduced several new files for
common variations of the model"

lines lines, we have mostly cleanups, the affected platforms are
OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus

Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now

it is intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
of chips meant for managed gigabit ethernet switches, based
around a Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2
and Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation.

Patch series "kmemcheck: kill kmemcheck", v2.
As discussed at LSF/MM, kill kmemcheck.
KASan is a replacement that is able to work without the limitation of
kmemcheck (single CPU, slow). KASan is already upstream.
We are also not aware of any users of kmemcheck (or users who don't
consider KASan as a suitable replacement).
The only objection was that since KASAN wasn't supported by all GCC
versions provided by distros at that time we should hold off for 2
years, and try again.
Now that 2 years have passed, and all distros provide gcc that supports
KASAN, kill kmemcheck again for the very same reasons.
This patch (of 4):
Remove kmemcheck annotations, and calls to kmemcheck from the kernel.
[alexander.levin@verizon.com: correctly remove kmemcheck call from dma_map_sg_attrs]

Let's add wrappers for ->nr_ptes with the same interface as for nr_pmd
and nr_pud.
The patch also makes nr_ptes accounting dependent onto CONFIG_MMU. Page
table accounting doesn't make sense if you don't have page tables.
It's preparation for consolidation of page-table counters in mm_struct.

Pull arm64 updates from Will Deacon:
"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.
Plenty of acronym soup here:
- initial support for the Scalable Vector Extension (SVE)
- improved handling for SError interrupts (required to handle RAS
events)
- enable GCC support for 128-bit integer types
- remove kernel text addresses from backtraces and register dumps
- use of WFE to implement long delay()s
- ACPI IORT updates from Lorenzo Pieralisi

"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where
they have been for a while. They are namely:
- to-gpiod conversion of the i2c-gpio driver and its users (touching
arch/* and drivers/mfd/*)
- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)
Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.
- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.
- at24 driver has way better OF support. And it has a new maintainer.

Here is the "big" staging and IIO driver update for 4.15-rc1.
Lots and lots of little changes, almost all minor code cleanups as the
Outreachy application process happened during this development cycle.
Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd atomisp
cleanups (take the media tree's version).

Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.
Specifics:
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to
support power management driver flags allowing device drivers to

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

Pull irq core updates from Thomas Gleixner:
"A rather large update for the interrupt core code and the irq chip drivers:
- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate
pull request. This allows to replace the convoluted nested loop
allocation function in x86 with a facility which supports the
recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.

range selectors.

- Extend x86 Intel free-running PEBS support and support x86
user-register sampling in perf record and perf script. (Andi Kleen)
Tooling:
- Completely rework the way inline frames are handled. Instead of
querying for the inline nodes on-demand in the individual tools, we
now create proper callchain nodes for inlined frames. (Milian

- 'perf trace' updates (Arnaldo Carvalho de Melo)
- Implement a way to print formatted output to per-event files in
'perf script' to facilitate generate flamegraphs, elliminating the
need to write scripts to do that separation (yuzhoujian, Arnaldo

- Multithread the synthesizing of PERF_RECORD_ events for
pre-existing threads in 'perf top', speeding up that phase, greatly
improving the user experience in systems such as Intel's Knights
Mill (Kan Liang)
- Introduce the concept of weak groups in 'perf stat': try to set up
a group, but if it's not schedulable fallback to not using a group.
That gives us the best of both worlds: groups if they work, but
still a usable fallback if they don't. E.g: (Andi Kleen)

macro 'GPIO_GPIO21'
GPIO_LOOKUP_IDX("gpio", GPIO_GPIO21, NULL, 0,
This is what happened:
commit b2e6355559
"i2c: gpio: Convert to use descriptors"
commit 4d0ce62c0a
"i2c: gpio: Augment all boardfiles to use open drain"
together uncovered an old bug in the Simpad board
file: as theGPIO_LOOKUP_IDX() encodes GPIO offsets
on gpiochips in an u16 (see <linux/gpio/machine.h>)
these GPIO "numbers" does not fit, since in
arch/arm/mach-sa1100/include/mach/SA-1100.h it is
defined as:
#define GPIO_GPIO(Nb) (0x00000001 << (Nb))
(...)
#define GPIO_GPIO21 GPIO_GPIO(21) /* GPIO [21] */
This is however provably wrong, since the i2c-gpio
driver uses proper GPIO numbers, albeit earlier from
the global number space, whereas this GPIO_GPIO21
is the local line offset in the GPIO register, which
is used in other code but certainly not in the
gpiolib GPIO driver in drivers/gpio/gpio-sa1100.c, which
has code like this:
static void sa1100_gpio_set(struct gpio_chip *chip,
unsigned offset, int value)
{
int reg = value ? R_GPSR : R_GPCR;
writel_relaxed(BIT(offset),
sa1100_gpio_chip(chip)->membase + reg);
}
So far everything however compiled fine as an unsigned
int was used to pass the GPIO numbers in
struct i2c_gpio_platform_data. We can trace the actual error
back to
commit dbd406f9d0
"ARM: 7025/1: simpad: add GPIO based device definitions."
This added the i2c_gpio with the wrong offsets.
This commit was before the SA1100 was converted to use
the gpiolib, but as can be seen from the contemporary
gpio.c in mach-sa1100, it was already using:
static int sa1100_gpio_get(struct gpio_chip *chip,
unsigned offset)
{
return GPLR & GPIO_GPIO(offset);
}
And GPIO_GPIO() is essentially the BIT() macro.

In order to control the GICv4 view of virtual CPUs, we rely
on an irqdomain allocated for that purpose. Let's add a couple
of helpers to that effect.
At the same time, the vgic data structures gain new fields to
track all this... erm... wonderful stuff.
The way we hook into the vgic init is slightly convoluted. We
need the vgic to be initialized (in order to guarantee that
the number of vcpus is now fixed), and we must have a vITS
(otherwise this is all very pointless). So we end-up calling
the init from both vgic_init and vgic_its_create.

ARM: 8720/1: ensure dump_instr() checks addr_limit
If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.
Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.
One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.
Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled. All clutter things in Makefiles go away.
As a bonus clean-up, I also removed dts-dirs. Just use subdir-y
directly to traverse sub-directories.

The grant v2 support was removed from the kernel with
commit 438b33c714 ("xen/grant-table:
remove support for V2 tables") as the higher memory footprint of v2
grants resulted in less grants being possible for a kernel compared
to the v1 grant interface.
As machines with more than 16TB of memory are expected to be more
common in the near future support of grant v2 is mandatory in order
to be able to run a Xen pv domain at any memory location.
So re-add grant v2 support basically by reverting above commit.

kvm_vcpu_dabt_isextabt() tries to match a full fault syndrome, but
calls kvm_vcpu_trap_get_fault_type() that only returns the fault class,
thus reducing the scope of the check. This doesn't cause any observable
bug yet as we end-up matching a closely related syndrome for which we
return the same value.

As we are about to be lazy with saving and restoring the timer
registers, we prepare by moving all possible timer configuration logic
out of the hyp code. All virtual timer registers can be programmed from
EL1 and since the arch timer is always a level triggered interrupt we
can safely do this with interrupts disabled in the host kernel on the
way to the guest without taking vtimer interrupts in the host kernel
(yet).
The downside is that the cntvoff register can only be programmed from
hyp mode, so we jump into hyp mode and back to program it. This is also
safe, because the host kernel doesn't use the virtual timer in the KVM
code. It may add a little performance performance penalty, but only
until following commits where we move this operation to vcpu load/put.

When CONFIG_DEBUG_USER is enabled, it's possible for a user to
deliberately trigger dump_instr() with a chosen kernel address.
Let's avoid problems resulting from this by using get_user() rather than
__get_user(), ensuring that we don't erroneously access kernel memory.
So that we can use the same code to dump user instructions and kernel
instructions, the common dumping code is factored out to __dump_instr(),
with the fs manipulated appropriately in dump_instr() around calls to
this.

The reworked MPU code produces a new warning in some configurations,
presumably starting with the code move after the compiler now makes
different inlining decisions:
arch/arm/mm/pmsa-v7.c: In function 'adjust_lowmem_bounds_mpu':
arch/arm/mm/pmsa-v7.c:310:5: error: 'specified_mem_size' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This appears to be harmless, as we know that there is always at
least one memblock, and the only way this could get triggered is
if the for_each_memblock() loop was never entered.
I could not come up with a better workaround than initializing
the specified_mem_size to zero, but at least that is the value
that the variable would have in the hypothetical case of no
memblocks.

Until KVM has full SVE support, guests must not be allowed to
execute SVE instructions.
This patch enables the necessary traps, and also ensures that the
traps are disabled again on exit from the guest so that the host
can still use SVE if it wants to.
On guest exit, high bits of the SVE Zn registers may have been
clobbered as a side-effect the execution of FPSIMD instructions in
the guest. The existing KVM host FPSIMD restore code is not
sufficient to restore these bits, so this patch explicitly marks
the CPU as not containing cached vector state for any task, thus
forcing a reload on the next return to userspace. This is an
interim measure, in advance of adding full SVE awareness to KVM.
This marking of cached vector state in the CPU as invalid is done
using __this_cpu_write(fpsimd_last_state, NULL) in fpsimd.c. Due
to the repeated use of this rather obscure operation, it makes
sense to factor it out as a separate helper with a clearer name.
This patch factors it out as fpsimd_flush_cpu_state(), and ports
all callers to use it.
As a side effect of this refactoring, a this_cpu_write() in
fpsimd_cpu_pm_notifier() is changed to __this_cpu_write(). This
should be fine, since cpu_pm_enter() is supposed to be called only

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

Many user space API headers have licensing information, which is either
incomplete, badly formatted or just a shorthand for referring to the
license under which the file is supposed to be. This makes it hard for
compliance tools to determine the correct license.
Update these files with an SPDX license identifier. The identifier was
chosen based on the license information in the file.
GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license
identifier with the added 'WITH Linux-syscall-note' exception, which is
the officially assigned exception identifier for the kernel syscall
exception:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
This exception makes it possible to include GPL headers into non GPL
code, without confusing license compliance tools.
Headers which have either explicit dual licensing or are just licensed
under a non GPL license are updated with the corresponding SPDX
identifier and the GPLv2 with syscall exception identifier. The format
is:
((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE)
SPDX license identifiers are a legally binding shorthand, which can be
used instead of the full boiler plate text. The update does not remove
existing license information as this has to be done on a case by case
basis and the copyright holders might have to be consulted. This will
happen in a separate step.

Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.
By default are files without license information under the default
license of the kernel, which is GPLV2. Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
otherwise syscall usage would not be possible.
Update the files which contain no license information with an SPDX
license identifier. The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception. SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The AXP81x family of PMIC is used with the Allwinner A83T and H8 SoCs.
This includes the AXP813 and AXP818. There is no discernible difference
except the labeling. The AXP813 is paired with the A83T, while the
AXP818 is paired with the H8.
This patch adds a dtsi file for all the common bindings for these two
PMICs. Currently this is just listing all the regulator nodes. The
regulators are initialized based on their device node names.
In the future this would be expanded to include power supplies and
GPIO controllers.

ARM depends on the macros '__ARMEL__' & '__ARMEB__' being defined
or not to correctly select or define endian-specific macros,
structures or pieces of code.
These macros are predefined by the compiler but sparse knows
nothing about them and thus may pre-process files differently
from what gcc would.
Fix this by passing '-D__ARMEL__' or '-D__ARMEB__' to sparse,
depending on the endianness of the kernel, like defined by GCC.
Note: In most case it won't change anything since most ARMs use
little-endian (but an allyesconfig would use big-endian!).

cm_split_idlest doesn't take the CM base offset into account right now,
causing it to read reserved registers which show idlestatus as active
always. This will cause the wait_module_ready functionality to be
effectively an expensive NOP, which will cause problems if the
module hasn't really activated during its execution. Fix by adding
the CM offset into the calculation so the wait_module_ready will
access correct register.

Adds support for the CEC controller found on Tegra124 and enables it on
Tegra K1.

ARM: tegra: Enable CEC support on Jetson TK1
ARM: tegra: Add CEC support for Tegra124
* r8a77430 (RZ/G1M) SoC
- Add XHCI support to SoC DT. Boards may enable this as appropriate
* All Renesas ARM based SoCs
- Add missing clocks for ARM CPU cores
Geert Uytterhoeven says "This series improves DT hardware descriptions
for Renesas arm32 SoCs by adding missing clocks properties to the
device nodes corresponding to ARM CPU cores."
* R-Car Gen 1 and 2, and RZ/G SoCs
- Use R-Car Fallback compat strings for GPIO
Simon Horman says "Use newly added R-Car GPIO Gen 1, 2 and 3 fallback
compat strings in peace of now deprecated non-generation specific R-Car
GPIO fallback compat string in the DT of Renesas ARM and arm64 based
SoCs.
As noted in the changelogs for the r8a777[89] changes, this introduces
an incompatibility with pre-v4.14 kernels used with new DTBs. There is
no run-time effect for other SoCs updated by this changeset."
* r7s72100 (RZ/A1H) GR-Peach board
- Add pin configuration subnode for ETHER pin group.
This avoids relying on boot-loader configuration of these pins.
- Enable ostm0 and ostm1 timers
Jacopo Mondi says these are "to be used as clock source and clockevent
source. The timers provides greater accuracy than the already enabled
mtu2 one."
- Correct leds node name indent
- Enable MTU2 timer pulse unit
Jacopo Mondi says "MTU2 multi-function/multi-channel timer/counter is
not enabled for GR-Peach board. The timer is used as clock event source
to schedule wake-ups, and without this enabled all sleeps not performed
through busy waiting hang the board."
* r8a7743 (RZ/G1M) iW-RainboW-G20M-Qseven SoM
- Add USB function support
* r8a7745 (RZ/G1E) iW-RainboW-G22D development platform
- Add USB2.0 Host support
* r8a7743 (RZ/G1M) iW-RainboW-G20D-Qseven development platform
- Rework DT architecture and add DT for camera DB
Fabrizio Castro says "Some of the serial interfaces are exposed on the
camera daughter board. The camera daughter board can be connected to
the carrier board by means of expansion connectors 1, 2 and 3. The
carrier board may host an RZ/G1M or an RZ/G1N based SoM.
While adding support for the serial interfaces on the camera daughter
board we faced the dilemma of how to properly describe all of the
possible HW configurations and how to maximize code reuse.
The best option would be to use device tree overlays, however there is
still some work to be done on that front before actually using them,
therefore for the time being we decided to provide .dtsi files to
describe the carrier board and the camera daughter board, and provide
.dts files to describe the HW configurations we need to support."
* r8a779[0-4] R-Car Gen2 SoCs
- Use generic node name for VSP1 nodes
Geert Uytterhoeven says "This patch series replaces the specific node
names used for the VSP1 nodes by the preferred generic node names, cfr.
commit 0e1bfb72b0 ("v4l: vsp1: Use generic node name")."
