Both port and ports names may be used in a panel-lvds binding
port - for a single port
ports - if there is more than one port in sub-nodes
Fixes the following warning:
advantech,idk-2121wr.example.dt.yaml: panel-lvds: 'port' is a required property
advantech,idk-2121wr.yaml needs several ports, so uses a ports node.
v2:
- Use oneOf - makes the logic more obvious (Rob)
- Added Fixes tag
- Added port: true, ports:true
v3:
- Indent port/ports in required two spaces (Rob)

The EFI handover protocol was introduced on x86 to permit the boot
loader to pass a populated boot_params structure as an additional
function argument to the entry point. This allows the bootloader to
pass the base and size of a initrd image, which is more flexible
than relying on the EFI stub's file I/O routines, which can only
access the file system from which the kernel image itself was loaded
from firmware.
This approach requires a fair amount of internal knowledge regarding
the layout of the boot_params structure on the part of the boot loader,
as well as knowledge regarding the allowed placement of the initrd in
memory, and so it has been deprecated in favour of a new initrd loading
method that is based on existing UEFI protocols and best practices.
So update the x86 boot protocol documentation to clarify that the EFI
handover protocol has been deprecated, and while at it, add a note that
invoking the EFI handover protocol still requires the PE/COFF image to
be loaded properly (as opposed to simply being copied into memory).
Also, drop the code32_start header field from the list of values that
need to be provided, as this is no longer required.

Commit 944d9fec8d ("hugetlb: add support for gigantic page allocation
at runtime") has added the run-time allocation of gigantic pages.
However it actually works only at early stages of the system loading,
when the majority of memory is free. After some time the memory gets
fragmented by non-movable pages, so the chances to find a contiguous 1GB
block are getting close to zero. Even dropping caches manually doesn't
help a lot.
At large scale rebooting servers in order to allocate gigantic hugepages
is quite expensive and complex. At the same time keeping some constant
percentage of memory in reserved hugepages even if the workload isn't
using it is a big waste: not all workloads can benefit from using 1 GB
pages.
The following solution can solve the problem:
1) On boot time a dedicated cma area* is reserved. The size is passed
as a kernel argument.
2) Run-time allocations of gigantic hugepages are performed using the
cma allocator and the dedicated cma area
In this case gigantic hugepages can be allocated successfully with a
high probability, however the memory isn't completely wasted if nobody
is using 1GB hugepages: it can be used for pagecache, anon memory, THPs,
etc.
* On a multi-node machine a per-node cma area is allocated on each node.
Following gigantic hugetlb allocation are using the first available
numa node if the mask isn't specified by a user.
Usage:
1) configure the kernel to allocate a cma area for hugetlb allocations:
pass hugetlb_cma=10G as a kernel argument
2) allocate hugetlb pages as usual, e.g.
echo 10 > /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
If the option isn't enabled or the allocation of the cma area failed,
the current behavior of the system is preserved.
x86 and arm-64 are covered by this patch, other architectures can be
trivially added later.
The patch contains clean-ups and fixes proposed and implemented by Aslan
Bakirov and Randy Dunlap. It also contains ideas and suggestions
proposed by Rik van Riel, Michal Hocko and Mike Kravetz. Thanks!

A couple of bug fixes for the main IPMI driver, one functional and two
annotations.
The kcs driver has some significant updates that have been pending for a
while, but I forgot to include in next until a week ago. But this code
is only used by the people who are sending it to me, really, so it's not
a big deal. I did want it to sit in next for at least a week, and it did
result in a fix.

As Documentation/kbuild/llvm.rst implies, building the kernel with a
full set of LLVM tools gets very verbose and unwieldy.
Provide a single switch LLVM=1 to use Clang and LLVM tools instead
of GCC and Binutils. You can pass it from the command line or as an
environment variable.
Please note LLVM=1 does not turn on the integrated assembler. You need
to pass LLVM_IAS=1 to use it. When the upstream kernel is ready for the
integrated assembler, I think we can make it default.
We discussed what we need, and we agreed to go with a simple boolean
flag that switches both target and host tools:
https://lkml.org/lkml/2020/3/28/494https://lkml.org/lkml/2020/4/3/43
Some items discussed, but not adopted:
- LLVM_DIR
When multiple versions of LLVM are installed, I just thought supporting
LLVM_DIR=/path/to/my/llvm/bin/ might be useful.
CC = $(LLVM_DIR)clang
LD = $(LLVM_DIR)ld.lld
...
However, we can handle this by modifying PATH. So, we decided to not do
this.
- LLVM_SUFFIX
Some distributions (e.g. Debian) package specific versions of LLVM with
naming conventions that use the version as a suffix.
CC = clang$(LLVM_SUFFIX)
LD = ld.lld(LLVM_SUFFIX)
...
will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc.,
but the suffixed versions in /usr/bin/ are symlinks to binaries in
/usr/lib/llvm-#/bin/, so this can also be handled by PATH.

The 'AS' variable is unused for building the kernel. Only the remaining
usage is to turn on the integrated assembler. A boolean flag is a better
fit for this purpose.
AS=clang was added for experts. So, I replaced it with LLVM_IAS=1,

Regular files opened with O_NONBLOCK allow read to return after a single
round-trip with the server instead of trying to fill buffer.
Add a few lines in 9p documentation to describe that.

The currently minimum-supported binutils version 2.21 has the problem of
promoting symbols which are defined outside of a section into absolute.
According to Arvind:
binutils-2.21 and -2.22. An x86-64 defconfig will fail with
Invalid absolute R_X86_64_32S relocation: _etext
and after fixing that one, with
Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve
Those two versions of binutils have a bug when it comes to handling
symbols defined outside of a section and binutils 2.23 has the proper
fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html
Therefore, up to the fixed version directly, skipping the broken ones.
Currently shipping distros already have the fixed binutils version so
there should be no breakage resulting from this.
For more details about the whole thing, see the thread in Link.

In this round, we've mainly focused on fixing bugs and addressing issues in
recently introduced compression support.
Enhancement:
- add zstd support, and set LZ4 by default
- add ioctl() to show # of compressed blocks
- show mount time in debugfs
- replace rwsem with spinlock
- avoid lock contention in DIO reads
Some major bug fixes wrt compression:
- compressed block count
- memory access and leak
- remove obsolete fields
- flag controls
Other bug fixes and clean ups:
- fix overflow when handling .flags in inode_info
- fix SPO issue during resize FS flow
- fix compression with fsverity enabled
- potential deadlock when writing compressed pages
- show missing mount options

"On x86" and "On SPARC" are now definition list terms, like

The Credits list is now a bulleted list, like lots of Credits lists in

The compressed cache for swap pages (zswap) currently needs from 1 to 3
extra kernel command line parameters in order to make it work: it has to
be enabled by adding a "zswap.enabled=1" command line parameter and if one
wants a different compressor or pool allocator than the default lzo / zbud
combination then these choices also need to be specified on the kernel
command line in additional parameters.
Using a different compressor and allocator for zswap is actually pretty
common as guides often recommend using the lz4 / z3fold pair instead of
the default one. In such case it is also necessary to remember to enable
the appropriate compression algorithm and pool allocator in the kernel
config manually.
Let's avoid the need for adding these kernel command line parameters and
automatically pull in the dependencies for the selected compressor
algorithm and pool allocator by adding an appropriate default switches to
Kconfig.
The default values for these options match what the code was using
previously as its defaults.

In commit 357b4da50a ("x86: respect memory size limiting via mem=
parameter") a global varialbe max_mem_size is added to store the value
parsed from 'mem= ', then checked when memory region is added. This truly
stops those DIMMs from being added into system memory during boot-time.
However, it also limits the later memory hotplug functionality. Any DIMM
can't be hotplugged any more if its region is beyond the max_mem_size. We
will get errors like:
[ 216.387164] acpi PNP0C80:02: add_memory failed
[ 216.389301] acpi PNP0C80:02: acpi_memory_enable_device() error
[ 216.392187] acpi PNP0C80:02: Enumeration failure
This will cause issue in a known use case where 'mem=' is added to the
hypervisor. The memory that lies after 'mem=' boundary will be assigned
to KVM guests. After commit 357b4da50a merged, memory can't be extended
dynamically if system memory on hypervisor is not sufficient.
So fix it by also checking if it's during boot-time restricting to add
memory. Otherwise, skip the restriction.
And also add this use case to document of 'mem=' kernel parameter.

The thp_fault_fallback and thp_file_fallback vmstats are incremented if
either the hugepage allocation fails through the page allocator or the
hugepage charge fails through mem cgroup.
This patch leaves this field untouched but adds two new fields,
thp_{fault,file}_fallback_charge, which is incremented only when the mem
cgroup charge fails.
This distinguishes between attempted hugepage allocations that fail due to
fragmentation (or low memory conditions) and those that fail due to mem
cgroup limits. That can be used to determine the impact of fragmentation
on the system by excluding faults that failed due to memcg usage.

The existing thp_fault_fallback indicates when thp attempts to allocate a
hugepage but fails, or if the hugepage cannot be charged to the mem cgroup
hierarchy.
Extend this to shmem as well. Adds a new thp_file_fallback to complement
thp_file_alloc that gets incremented when a hugepage is attempted to be
allocated but fails, or if it cannot be charged to the mem cgroup
hierarchy.
Additionally, remove the check for CONFIG_TRANSPARENT_HUGE_PAGECACHE from
shmem_alloc_hugepage() since it is only called with this configuration
option.

Michael noticed that userns limit for number of time namespaces is missing.
Furthermore, time namespace introduced UCOUNT_TIME_NAMESPACES, but didn't
introduce an array member in user_table[]. It would make array's
initialisation OOB write, but by luck the user_table array has an excessive
empty member (all accesses to the array are limited with UCOUNT_COUNTS - so
it silently reuses the last free member.
Fixes user-visible regression: max_inotify_instances by reason of the
missing UCOUNT_ENTRY() has limited max number of namespaces instead of the
number of inotify instances.

Pull more power management updates from Rafael Wysocki:
"Additional power management updates.
These fix a corner-case suspend-to-idle wakeup issue on systems where
the ACPI SCI is shared with another wakeup source, add a kernel
command line option to set pm_debug_messages via the kernel command
line, add a document desctibing system-wide suspend and resume code
flows, modify cpufreq Kconfig to choose schedutil as the preferred
governor by default in a couple of cases and do some assorted
cleanups.
Specifics:
- Fix corner-case suspend-to-idle wakeup issue on systems where the
ACPI SCI is shared with another wakeup source (Hans de Goede).
- Add document describing system-wide suspend and resume code flows
to the admin guide (Rafael Wysocki).
- Add kernel command line option to set pm_debug_messages (Chen Yu).
- Choose schedutil as the preferred scaling governor by default on
ARM big.LITTLE systems and on x86 systems using the intel_pstate
driver in the passive mode (Linus Walleij, Rafael Wysocki).
- Drop racy and redundant checks from the PM core's device_prepare()
routine (Rafael Wysocki).
- Make resume from hibernation take the hibernation_restore() return
value into account (Dexuan Cui)"

- A large series from Nick for 64-bit to further rework our exception vectors,
and rewrite portions of the syscall entry/exit and interrupt return in C. The
result is much easier to follow code that is also faster in general.
- Cleanup of our ptrace code to split various parts out that had become badly
intertwined with #ifdefs over the years.
- Changes to our NUMA setup under the PowerVM hypervisor which should
hopefully avoid non-sensical topologies which can lead to warnings from the
workqueue code and other problems.

majority of the diff is the normal collection of driver additions for new SoCs
and non-critical clk data fixes and updates. The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and Unisoc
support added a handful of big drivers for new SoCs but that's not really the
whole story because those new drivers tend to add large numbers of lines of clk
data. There's a handful of AT91 clk drivers added this time around too and a
bunch of improvements to drivers like the i.MX driver. All around lots of
updates and fixes in various clk drivers which is good to see.
The core framework has only one real major change which has been baking in next
for the past couple months. It fixes the framework so that it stops caching a
clk's phase when the phase clk_op returns an error. Before this change we would
consider some negative errno as a phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for pll1443x table,
and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need to
change ARM PLL frequency. Thus, we can support core running above
1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate for
getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d
- Remove PMC clks from Tegra clk driver
- Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector
- Conversion to json-schema of the Renesas CPG/MSSR DT bindings
- Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N
- Update Amlogic audio clock gate hierarchy for meson8 and gxbb
- Update Amlogic g12a spicc clock sources
- Support for Ingenic X1000 TCU clks

- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and reading
as it acted like the normal producer/consumer. As the trace file
would not consume the data, the easy way of handling it was to just
disable writes to the ring buffer. This came to a surprise to the
BPF folks who complained about lost events due to reading.
This is no longer an issue. If someone wants to keep the old disabling
there's a new option "pause-on-trace" that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be traced
by the function tracer. Similar to set_ftrace_pid, which makes the
function tracer only trace those tasks with PIDs in the file, the
set_ftrace_notrace_pid does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced.
Note, sched_waking and sched_switch events may still be trace if
one of the tasks referenced by those events contains a PID that
is allowed to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file
is searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get
off debugfs (acked by Greg Kroah-Hartman)

Merge tag 'rtc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"More cleanup this cycle, with the final goal of removing the
rtc_time_to_tm and rtc_tm_to_time wrappers. All the drivers that have
been modified for this now are ready for the end of times (whether it
happens in 2033, 2038, 2106, 2127 or even 4052). There is also a
single new driver and the usual fixes and features.
Summary:
Subsystem:
- The rtc_time_to_tm and rtc_tm_to_time wrappers have finally been
removed and only the 64bit version remain.
- hctosys now works with drivers compiled as modules
New driver:
- MediaTek MT2712 SoC based RTC
Drivers:
- set range for 88pm860x, au1xxx, cpcap, da9052, davinci, ds1305,
ds1374, mcp5121, pl030, pl031, pm8xxx, puv3, sa1100, sirfsoc,
starfire, sun6i
- ds1307: DS1388 oscillator failure detection and watchdog support
- jz4740: JZ4760 support
- pcf85063: clock out pin support
- sun6i: external 32k oscillator is now optional, the range is now
handled by the core, providing a solution for 2034"

Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that
do not block interrupts. This makes us better at getting
events to userspace without blocking or disturbing new events
arriving in the same time. This was reviewed by the KFIFO
maintainer Stefani. This is a generic improvement which
paves the road for similar improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines
and giving them back, possibly reconfiguring them in the
process: we can now monitor that and not get stuck with stale
static information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could
move forward and *backward* in time, which probably would just
cause silent bugs and weird behaviour. In the long run we
see two relevant timestamps: ktime_get_ns() or the timestamp
sometimes provided by the GPIO hardware itself, if that
exists.
- Device Tree overlay support for GPIO hogs. On systems that
load overlays, these overlays can now contain hogs, and will
then be respected.
- Handle pin control interaction with nonexisting pin ranges
in the GPIO library core instead of in the individual
drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
MMIO GPIO library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements,
such as blocking of idle on pending GPIO interrupts.

Pull cgroup updates from Tejun Heo:
- Christian extended clone3 so that processes can be spawned into
cgroups directly.
This is not only neat in terms of semantics but also avoids grabbing
the global cgroup_threadgroup_rwsem for migration.
- Daniel added !root xattr support to cgroupfs.
Userland already uses xattrs on cgroupfs for bookkeeping. This will
allow delegated cgroups to support such usages.
- Prateek tried to make cpuset hotplug handling synchronous but that
led to possible deadlock scenarios. Reverted.

This introduces a range of improvements to the OMAP remoeteproc driver;
among other things adding devicetree, suspend/resume and watchdog
support, and adds support the remoteprocs in the DRA7xx SoC.
It introduces support for 64-bit firmware, extends the ELF loader to
support this and fixes for a number of race conditions in the recovery
handling.
It introduces a generic mechanism to allow remoteproc drivers to sync
state with remote processors during a panic, and uses this to prepare
Qualcomm remote processors for post mortem analysis.
Finally it introduces fixes to cleanly recover from crashes in the modem
firmware on production Qualcomm devices.

Merge tag 'rproc-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc
Pull remoteproc updates from Bjorn Andersson:
- a range of improvements to the OMAP remoeteproc driver; among other
things adding devicetree, suspend/resume and watchdog support, and
adds support the remoteprocs in the DRA7xx SoC
- support for 64-bit firmware, extends the ELF loader to support this
and fixes for a number of race conditions in the recovery handling
- a generic mechanism to allow remoteproc drivers to sync state with
remote processors during a panic, and uses this to prepare Qualcomm
remote processors for post mortem analysis
- fixes to cleanly recover from crashes in the modem firmware on
production Qualcomm devices

* GICv4.1 support
* 32bit host removal
PPC:
* secure (encrypted) using under the Protected Execution Framework
ultravisor
s390:
* allow disabling GISA (hardware interrupt injection) and protected
VMs/ultravisor support.
x86:
* New dirty bitmap flag that sets all bits in the bitmap when dirty
page logging is enabled; this is faster because it doesn't require bulk
modification of the page tables.
* Initial work on making nested SVM event injection more similar to VMX,
and less buggy.
* Various cleanups to MMU code (though the big ones and related
optimizations were delayed to 5.8). Instead of using cr3 in function
names which occasionally means eptp, KVM too has standardized on "pgd".
* A large refactoring of CPUID features, which now use an array that
parallels the core x86_features.
* Some removal of pointer chasing from kvm_x86_ops, which will also be
switched to static calls as soon as they are available.
* New Tigerlake CPUID features.
* More bugfixes, optimizations and cleanups.
Generic:
* selftests: cleanups, new MMU notifier stress test, steal-time test
* CSV output for kvm_stat.
KVM/MIPS has been broken since 5.5, it does not compile due to a patch committed
by MIPS maintainers. I had already prepared a fix, but the MIPS maintainers
prefer to fix it in generic code rather than KVM so they are taking care of it.
