Greg Kroah-Hartman c50099f856 Update extcon for 4.17
Detailed description for this pull request:
 1. Add exported extcon function in order to support OF graph binding
 - The extcon consumer driver used the "extcon = <&extcon's phandle"
   property in device-tree in order to bind between extcon provider
   and consumer driver. But, OF graph method is better than 'extcon' property.
   So, extcon subsystem adds the following function to support OF graph binding.
   : extcon_find_edev_by_node(struct device_node *node)
 
 - Create the immutable branch ("ib-extcon-drm-dt-v4.17") for both drm-misc
   and device-tree subsystem. This immutable branch contains the use-case of
   OF graph binding for EXTCON_HDMI connector between MHL device driver
   and extcon provider driver.
 
 2. Fix minor issues of extcon device drivers
 - Remove platform_data and covert to fully use GPIO descriptor for extcon-gpio.c
 - Remove workaround code for id pin direction from extcon-inte-int3496.c
   because GPIO ACPI library does support it with generic way.
 - Set direction and drv flags for V5 boost GPIO because of fixing
   the firmware bug.

David Lechner 21cdf7269f dt-bindings: clock: New bindings for TI Davinci PSC
This adds a new binding for the Power Sleep Controller (PSC) for the
mach-davinci family of processors.

Note: Although TI Keystone has a very similar PSC, we are not using the
existing bindings. Keystone is using a legacy one-node-per-clock binding
(actually two nodes if you count the separate reset binding for the same
IP block). Also, some davinci LPSCs have quirks that aren't handled by
the keystone bindings, so we would be adding one compatible string per
clock with quirks instead of just a new compatible string for each
controller.

David Lechner b6e37ce237 dt-bindings: clock: Add new bindings for TI Davinci PLL clocks
This adds a new binding for the PLL IP blocks in the mach-davinci
family of processors. Currently, only da850 has device tree support
but these bindings can also work for other SoCs in this family just
by adding new compatible strings.

Note: Although these PLL controllers are very similar to the TI Keystone
SoCs, we are not re-using those bindings. The Keystone bindings use a
legacy one-node-per-clock binding. Furthermore, the mach-davinici SoCs
have a slightly different PLL register layout and a number of quirks
that can't be handled by the existing bindings, so the keystone bindings
could not be used as-is anyway.

Rafael J. Wysocki 95c513ec84 ACPI: Add Time and Alarm Device (TAD) driver
Introduce a driver for the ACPI Time and Alarm Device (TAD) based on
Section 9.18 of ACPI 6.2.

This driver only supports the system wakeup capabilities of the TAD
which are mandatory.  Support for the RTC capabilities of the TAD
will be added to it in the future.

This driver is entirely sysfs-based.  It provides attributes (under
the TAD platform device) to allow user space to manage the AC and DC
wakeup timers of the TAD: set and read their values, set and check
their expire timer wake policies, check and clear their status and
check the capabilities of the TAD reported by AML.  The DC timer
attributes are only present if the TAD supports a separate DC alarm
timer.

The wakeup events handling and power management of the TAD is
expected to be taken care of by the ACPI PM domain attached to its
platform device.

Kai-Heng Feng 027bd6cafd usb: core: Add "quirks" parameter for usbcore
Trying quirks in usbcore needs to rebuild the driver or the entire
kernel if it's builtin. It can save a lot of time if usbcore has similar
ability like "usbhid.quirks=" and "usb-storage.quirks=".

Rename the original quirk detection function to "static" as we introduce
this new "dynamic" function.

Now users can use "usbcore.quirks=" as short term workaround before the
next kernel release. Also, the quirk parameter can XOR the builtin
quirks for debugging purpose.

This is inspired by usbhid and usb-storage.

drm/sun4i: Add compatible strings for A80 TCONs
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very
vague about the third TCON, to the point that it might not exist.

In the documentation, the first TCON is missing channel 1, and the
second is missing channel 0. However the vendor kernel seems to be
able to use them regardless. Here we model them like the old TCONs.

An oddity is that TCON0 requires the reset control for the eDP block
to be deasserted, for any register access to stick.

This patch adds compatible strings for TCON0 and TCON1, with TCON0
requiring an extra "edp" reset control.

We're now ready to map our vectors in weird and wonderful locations.
On enabling ARM64_HARDEN_EL2_VECTORS, a vector slot gets allocated
if this hasn't been already done via ARM64_HARDEN_BRANCH_PREDICTOR
and gets mapped outside of the normal RAM region, next to the
idmap.

That way, being able to obtain VBAR_EL2 doesn't reveal the mapping

Khalid Aziz 74a0496748 sparc64: Add support for ADI (Application Data Integrity)
ADI is a new feature supported on SPARC M7 and newer processors to allow
hardware to catch rogue accesses to memory. ADI is supported for data
fetches only and not instruction fetches. An app can enable ADI on its
data pages, set version tags on them and use versioned addresses to
access the data pages. Upper bits of the address contain the version
tag. On M7 processors, upper four bits (bits 63-60) contain the version
tag. If a rogue app attempts to access ADI enabled data pages, its
access is blocked and processor generates an exception. Please see
Documentation/sparc/adi.txt for further details.

This patch extends mprotect to enable ADI (TSTATE.mcde), enable/disable
MCD (Memory Corruption Detection) on selected memory ranges, enable
TTE.mcd in PTEs, return ADI parameters to userspace and save/restore ADI
version tags on page swap out/in or migration. ADI is not enabled by
default for any task. A task must explicitly enable ADI on a memory
range and set version tag for ADI to be effective for the task.

Commit "0a007b97aad6"(f2fs: recover directory operations by fsync)
fixed xfstest generic/342 case, but it also increased the written
data and caused the performance degradation. In most cases, there's
no need to do so heavy fsync actually.

So we introduce new mount option "fsync_mode={posix,strict}" to
control the policy of fsync. "fsync_mode=posix" is set by default,
and means that f2fs uses a light fsync, which follows POSIX semantics.
And "fsync_mode=strict" means that it's a heavy fsync, which behaves
in line with xfs, ext4 and btrfs, where generic/342 will pass, but
the performance will regress.

Tony Lindgren 5d1ebbda03 phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4
Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.

The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.

The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.

The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.

Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.

Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.

For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:

idle lcd off	phy-mapphone-mdm6600	ohci-platform
153mW		284mW			344mW

So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

Arnd Bergmann bb9d812643 arch: remove tile port
The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

Martin Blumenstingl 324e46cee1 dt-bindings: phy: Add support for the USB3 PHY on Amlogic Meson GXL SoCs
Amlogic Meson GXL SoCs use a dwc3 controller with two (GXM - a variant
for GXL, has three) USB2 ports. The first USB2 port supports host and
peripheral (also called "device") mode.
While the dwc3 controller has no USB3 port enabled we still need the
USB3 PHY to be initialized. Otherwise high-speed USB transfers (for
example with a USB flash drive) may time out (most often seen on boards
with mainline u-boot, where the bootloader does not initialize the USB3
PHY registers).

This change introduces a proposed layout for describing FSI busses in
the device tree. While the bus is probe-able, we'd still like a method
of describing subordinate (eg i2c) busses that are behind FSI devices.

The FSI core will be responsible for matching probed slaves & engines to
their device tree nodes, so the FSI device drivers' probe() functions
will be passed a struct device with the appropriate of_node populated
where a matching DT node is found.

Jeremy Kerr b8bd146d38 fsi: master-gpio: Add external mode
This change introduces an 'external mode' for GPIO-based FSI masters,
allowing the clock and data lines to be driven by an external source.
For example, external mode is selected by a user when an external debug
device is attached to the FSI pins.

To do this, we need to set specific states for the trans, mux and enable
GPIOs, and prevent access to clk & data from the FSI core code (by
returning EBUSY).

External mode is controlled by a sysfs attribute, so add the relevant
information to Documentation/ABI/

Willem de Bruijn ced68234b6 sock: remove zerocopy sockopt restriction on closed tcp state
Socket option SO_ZEROCOPY determines whether the kernel ignores or
processes flag MSG_ZEROCOPY on subsequent send calls. This to avoid
changing behavior for legacy processes.

Limiting the state change to closed sockets is annoying with passive
sockets and not necessary for correctness. Once created, zerocopy skbs
are processed based on their private state, not this socket flag.

Remove the constraint.

Greg Kroah-Hartman 6761f0ac66 Second set of new device support, features and cleanup for IIO in the 4.17 cycle
The uptick in staging cleanup is partly due to GSoC Applications
 process being underway and one of Daniel's tasks being to try
 cleaning up an IIO driver to move out of staging.
 Naturally there is some normal staging cleanup progress in here
 as well.
 
 New device support
 * Microchip mcp4018
   - New driver supproting MCP4017, MCP4018 and MCP4019 digital pots.
 * On Semiconductor lv0104cs
   - New driver to support this ambient light sensor.
 
 Cleanup
 * axp20x_adc
   - remove a !! in favour of clear ternary operator.
 * ad2s1210 (staging cleanup)
   - Reorganise to avoid ending a line with [
   - Remove some unnecessary defines.
   - Remove unsed variable.
 * ad5380
   - Replace magic 0 with IIO_CHAN_INFO_RAW
 * ad5764
   - Replace magic 0 with IIO_CHA_INFO_RAW

   - Align arguements.
 * ad7746 (staging cleanup)
   - Align arguements.
 * ad7816
   - Remove pointless void pointer cast.
 * ade7753
   - Replace IIO_DEV_ATTR_CH_OFF with equivalent to avoid confusing
     checkpatch (this macro didn't really help anyway).  Also drop the
     macro from the meter.h header.
 * ade7754 (staging cleanup)
   - Add names to funciton definition arguements.
   - Align arguements with open parenthesis where possible.
 * ade7758 (staging cleanup)
   - Remove __func__ from dev_dbg statements as provided by dynamic
     debug anyway.
   - Align arguements with open parenthesis where possible.
 * ade7759 (staging cleanup)
   - Replace IIO_DEV_ATTR_CH_OFF with equiavalent to avoid confusing
     checkpatch.
 * adis16201 (staging cleanup)
   - Headers in alphabetical order.
   - Blank lines before returns.
 * adis16209 (staging cleanup)
   - Headers in alphabetical order
   - Change some definition names to make them more meaningful (2 rounds
     of this).
   - Add explicit _REG prefix to register names to make them
     obviously different from fields within those registers.
   - Remove some superflous comments and group definitions better.
   - Use a switch statement to make it semantically obvious that we
     only have two options (rather than an unlimited 'else').
   - Use sign_extent32 instead of open coding.
 * adt7316 (staging cleanup)
   - Move an export next to symbol.
 * bmc150
   - drop redundant __func__ in dynamic debug.
 * ccs811
   - Rename varaible to better reflect what it does.
 * cros_ec
   - Reduce sampling frequency before suspending to avoid preventing
     suspend.
 * dummy
   - Correct whitespace in Kconfig.
   - Add extra description in Kconfig.
 * ds1803
   - Remove a VLA which we always know is 2 long.
 * hid-sensor-accel
   - Replace magic number 0 by IIO_CHAN_INFO_RAW.
 * hid-sensor-gyro
   - Replace magic number 0 by IIO_CHAN_INFO_RAW.
 * hid-sensor-light
   - Replace magic number 0 by IIO_CHAN_INFO_RAW.

   - Fix the proximity sensor functionality.
   - Remove platform data provided power functions.  There are much
     better ways to do this these days.
   - Introduce some common functions to avoid various repititions.
   - Stop using mutex_trylock when mutex_lock and wait a bit is fine.
   - Improve error handling in various places.
   - Drop some 'Camel case' (which wasn't actually strickly camel case
     but was a bit odd.
   - Drop some _available sysfs attributes for things that don't exist
     (for particular supported parts).

Jonathan writes:

Second set of new device support, features and cleanup for IIO in the 4.17 cycle

The uptick in staging cleanup is partly due to GSoC Applications
process being underway and one of Daniel's tasks being to try
cleaning up an IIO driver to move out of staging.
Naturally there is some normal staging cleanup progress in here
as well.

New device support
* Microchip mcp4018
  - New driver supproting MCP4017, MCP4018 and MCP4019 digital pots.
* On Semiconductor lv0104cs
  - New driver to support this ambient light sensor.

Cleanup
* axp20x_adc
  - remove a !! in favour of clear ternary operator.
* ad2s1210 (staging cleanup)
  - Reorganise to avoid ending a line with [
  - Remove some unnecessary defines.
  - Remove unsed variable.
* ad5380
  - Replace magic 0 with IIO_CHAN_INFO_RAW
* ad5764
  - Replace magic 0 with IIO_CHA_INFO_RAW
* ad7150 (staging cleanup)
  - Align arguements with parenthesis.
* ad7152 (staging cleanup)
  - Align arguements.
* ad7746 (staging cleanup)
  - Align arguements.
* ad7816
  - Remove pointless void pointer cast.
* ade7753
  - Replace IIO_DEV_ATTR_CH_OFF with equivalent to avoid confusing
    checkpatch (this macro didn't really help anyway).  Also drop the
    macro from the meter.h header.
* ade7754 (staging cleanup)
  - Add names to funciton definition arguements.
  - Align arguements with open parenthesis where possible.
* ade7758 (staging cleanup)
  - Remove __func__ from dev_dbg statements as provided by dynamic
    debug anyway.
  - Align arguements with open parenthesis where possible.
* ade7759 (staging cleanup)
  - Replace IIO_DEV_ATTR_CH_OFF with equiavalent to avoid confusing
    checkpatch.
* adis16201 (staging cleanup)
  - Headers in alphabetical order.
  - Blank lines before returns.
* adis16209 (staging cleanup)
  - Headers in alphabetical order
  - Change some definition names to make them more meaningful (2 rounds
    of this).
  - Add explicit _REG prefix to register names to make them
    obviously different from fields within those registers.
  - Remove some superflous comments and group definitions better.
  - Use a switch statement to make it semantically obvious that we
    only have two options (rather than an unlimited 'else').
  - Use sign_extent32 instead of open coding.
* adt7316 (staging cleanup)
  - Move an export next to symbol.
* bmc150
  - drop redundant __func__ in dynamic debug.
* ccs811
  - Rename varaible to better reflect what it does.
* cros_ec
  - Reduce sampling frequency before suspending to avoid preventing
    suspend.
* dummy
  - Correct whitespace in Kconfig.
  - Add extra description in Kconfig.
* ds1803
  - Remove a VLA which we always know is 2 long.
* hid-sensor-accel
  - Replace magic number 0 by IIO_CHAN_INFO_RAW.
* hid-sensor-gyro
  - Replace magic number 0 by IIO_CHAN_INFO_RAW.
* hid-sensor-light
  - Replace magic number 0 by IIO_CHAN_INFO_RAW.
* hid-sensor-magn
  - Replace magic number 0 by IIO_CHAN_INFO_RAW.
* lm3533
  - Replace magic number 0 by IIO_CHAN_INFO_RAW
* mlx90632
  - Squash a smatch warning - no runtime effect.
* stm32_dfsdm:
  - Cleanup the dt bindings.
* sx9500
  - Add GPIO ACPI mapping table to behave correctly when firmware
    doesn't provide the mapping.
* tsl2x7x (staging cleanup)
  - Fix the proximity sensor functionality.
  - Remove platform data provided power functions.  There are much
    better ways to do this these days.
  - Introduce some common functions to avoid various repititions.
  - Stop using mutex_trylock when mutex_lock and wait a bit is fine.
  - Improve error handling in various places.
  - Drop some 'Camel case' (which wasn't actually strickly camel case
    but was a bit odd.
  - Drop some _available sysfs attributes for things that don't exist
    (for particular supported parts).

Marc Zyngier f736d65df0 irqchip/gic-v3: Allow LPIs to be disabled from the command line
For most GICv3 implementations, enabling LPIs is a one way switch.
Once they're on, there is no turning back, which completely kills
kexec (pending tables will always be live, and we can't tell the
secondary kernel where they are).

This is really annoying if you plan to use Linux as a bootloader,
as it pretty much guarantees that the secondary kernel won't be
able to use MSIs, and may even see some memory corruption. Bad.

A workaround for this unfortunate situation is to allow the kernel
not to enable LPIs, even if the feature is present in the HW. This
would allow Linux-as-a-bootloader to leave LPIs alone, and let the
secondary kernel to do whatever it wants with them.

Let's introduce a boolean "irqchip.gicv3_nolpi" command line option
that serves that purpose.

+					a 255-byte read);

+					(e.g morph devices), don't use reset);
+				f = USB_QUIRK_HONOR_BNUMINTERFACES (device has
+					more interface descriptions than the
+					bNumInterfaces count, and can't handle
+					talking to these interfaces);
+				g = USB_QUIRK_DELAY_INIT (device needs a pause
+					during initialization, after we read
+					the device descriptor);
+				h = USB_QUIRK_LINEAR_UFRAME_INTR_BINTERVAL (For
+					high speed and super speed interrupt
+					endpoints, the USB 2.0 and USB 3.0 spec
+					require the interval in microframes (1
+					microframe = 125 microseconds) to be

+					requests);
+				j = USB_QUIRK_IGNORE_REMOTE_WAKEUP (device
+					generates spurious wakeup, ignore
+					remote wakeup capability);
+				k = USB_QUIRK_NO_LPM (device can't handle Link
+					Power Management);
+				l = USB_QUIRK_LINEAR_FRAME_INTR_BINTERVAL
+					(Device reports its bInterval as linear

Gregory CLEMENT 3cd2c313f1 dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.

With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

Add a 'last error' facility accessible via the erroring event's 'hist'

information about what went wrong, if information is available.  This
extended error information will be available until the next hist
trigger command for that event.

  # echo xxx > /sys/kernel/debug/tracing/events/sched/sched_wakeup/trigger
  echo: write error: Invalid argument

  # cat /sys/kernel/debug/tracing/events/sched/sched_wakeup/hist

  ERROR: Couldn't yyy: zzz

This also adds an external trace_clock_in_ns() to trace.c for the

Tom Zanussi 2c1ea60b19 tracing: Add timestamp_mode trace file
Add a new option flag indicating whether or not the ring buffer is in
'absolute timestamp' mode.

Currently this is only set/unset by hist triggers that make use of a
common_timestamp.  As such, there's no reason to make this writeable
for users - its purpose is only to allow users to determine
unequivocally whether or not the ring buffer is in that mode (although
absolute timestamps can coexist with the normal delta timestamps, when
the ring buffer is in absolute mode, timestamps written while absolute
mode is in effect take up more space in the buffer, and are not as
efficient).

Instead of having an early init function check the machine compatible
and installing multi-cluster SMP support for the A80 if it matches,
use a new cpu enable-method string. This makes the platform support
future proof in case anyone manages to add PSCI support.

The original init code for the SMP support is changed into the
.prepare_cpus callback in the smp_operations structure. Instead of
panicing when resources are missing like on some platforms, our code
merely guards against engaging SMP or CPU hotplug and returns an error.

in 2016 by long-time maintainer David Howells.

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

Trying quirks in usbcore needs to rebuild the driver or the entire
kernel if it's builtin. It can save a lot of time if usbcore has similar
ability like "usbhid.quirks=" and "usb-storage.quirks=".

Rename the original quirk detection function to "static" as we introduce
this new "dynamic" function.

Now users can use "usbcore.quirks=" as short term workaround before the
next kernel release. Also, the quirk parameter can XOR the builtin
quirks for debugging purpose.

This is inspired by usbhid and usb-storage.

Dave Hansen 7f5d465f4d docs: clarify security-bugs disclosure policy
I think we need to soften the language a bit.  It might scare folks
off, especially the:

	 We prefer to fully disclose the bug as soon as possible.

which is not really the case.  Linus says:

	It's not full disclosure, it's not coordinated disclosure,
	and it's not "no disclosure".  It's more like just "timely
	open fixes".

I changed a bit of the wording in here, but mostly to remove the word
"disclosure" since it seems to mean very specific things to people
that we do not mean here.

ASoC: da7219: Add common clock usage for providing DAI clks
There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.

The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

Linus Torvalds a525df0558 powerpc fixes for 4.16 #5
One notable fix to properly advertise our support for a new firmware feature,
 caused by two series conflicting semantically but not textually.
 
 There's a new ioctl for the new ocxl driver, which is not a fix, but needed to
 complete the userspace API and good to have before the driver is in a released
 kernel.
 
 Finally three minor selftest fixes, and a fix for intermittent build failures
 for some obscure platforms, caused by a missing make dependency.

Eric Dumazet 79134e6ce2 net: do not create fallback tunnels for non-default namespaces
fallback tunnels (like tunl0, gre0, gretap0, erspan0, sit0,
ip6tnl0, ip6gre0) are automatically created when the corresponding
module is loaded.

These tunnels are also automatically created when a new network
namespace is created, at a great cost.

In many cases, netns are used for isolation purposes, and these
extra network devices are a waste of resources. We are using
thousands of netns per host, and hit the netns creation/delete
bottleneck a lot. (Many thanks to Kirill for recent work on this)

Add a new sysctl so that we can opt-out from this automatic creation.

Note that these tunnels are still created for the initial namespace,
to be the least intrusive for typical setups.

Tested:

Mika Westerberg 9aaa3b8b4c thunderbolt: Add support for preboot ACL
Preboot ACL is a mechanism that allows connecting Thunderbolt devices
boot time in more secure way than the legacy Thunderbolt boot support.
As with the legacy boot option, this also needs to be enabled from the
BIOS before booting is allowed. Difference to the legacy mode is that
the userspace software explicitly adds device UUIDs by sending a special
message to the ICM firmware. Only the devices listed in the boot ACL are
connected automatically during the boot. This works in both "user" and
"secure" security levels.

We implement this in Linux by exposing a new sysfs attribute (boot_acl)
below each Thunderbolt domain. The userspace software can then update
the full list as needed.

In various cases, Thunderbolt device can be connected by ICM on boot
without waiting for approval from user. Most cases are related to
OEM-specific BIOS configurations. This information is interesting for
user-space as if the device isn't in SW ACL, it may create a friction in
the user experience where the device is automatically authorized if it's
connected on boot but requires an explicit user action if connected
after OS is up. User-space can use this information to suggest adding
the device to SW ACL for auto-authorization on later connections.

Daniel Borkmann says:

====================
pull-request: bpf 2018-03-08

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix various BPF helpers which adjust the skb and its GSO information
   with regards to SCTP GSO. The latter is a special case where gso_size
   is of value GSO_BY_FRAGS, so mangling that will end up corrupting
   the skb, thus bail out when seeing SCTP GSO packets, from Daniel(s).

2) Fix a compilation error in bpftool where BPF_FS_MAGIC is not defined
   due to too old kernel headers in the system, from Jiri.

3) Increase the number of x64 JIT passes in order to allow larger images
   to converge instead of punting them to interpreter or having them
   rejected when the interpreter is not built into the kernel, from Daniel.

Arnd Bergmann f46f11dc1e ARM SCMI support for v4.17
ARM System Control and Management Interface(SCMI)[1] is more flexible and
 easily extensible than any of the existing interfaces.
 
 Few existing as well as future ARM platforms provide micro-controllers
 to abstract various power and other system management tasks which have
 similar interfaces, both in terms of the functions that are provided by
 them, and in terms of how requests are communicated to them.
 
 There are quite a few protocols like ARM SCPI, TI SCI, QCOM RPM, Nvidia Tegra
 BPMP, and so on already. This specification is to standardize and avoid any
 further fragmentation in the design of such interface by various vendors.
 
 The current SCMI driver implementation is very basic and initial support.
 It lacks support for notifications, asynchronous/delayed response, perf/power
 statistics region and sensor register region.
 
 Mailbox is the only form of transport supported currently in the driver.
 SCMI supports interrupt based mailbox communication, where, on completion
 of the processing of a message, the caller receives an interrupt as well as
 polling for completion.
 
 SCMI is designed to minimize the dependency on the mailbox/transport
 hardware. So in terms of SCMI, each channel in the mailbox includes
 memory area, doorbell and completion interrupt.
 
 However the doorbell and completion interrupt is highly mailbox dependent
 which was bit of controversial as part of SCMI/mailbox discussions.
 
 Arnd and me discussed about the few aspects of SCMI and the mailbox framework:
 
 1. Use of mailbox framework for doorbell type mailbox controller:
    - Such hardware may not require any data to be sent to signal the remote
      about the presence of a message. The channel will have in-built
      information on how to trigger the signal to the remote.
      There are few mailbox controller drivers which are purely doorbell based.
      e.g.QCOM IPC, STM, Tegra, ACPI PCC,..etc
 
 2. Supporting other mailbox controller:
    - SCMI just needs a mechanism to signal the remote firmware. Such
      controller may need fixed message to be sent to trigger a doorbell.
      In such case we may need to get that data from DT and pass the same
      to the controller. It's not covered in the current DT binding, but
      can be extended as optional property in future.
 
      However handling notifications may be interesting on such mailbox, but
      again there is no way to interpret what the data field(remote message)
      means, it could be a bit mask or a number or don't-care.
 
 Arnd mentioned that he doesn't like the way the mailbox binding deals
 with doorbell-type hardware, but we do have quite a few precedent drivers
 already and changing the binding to add a data field would not make it any
 better, but could cause other problems. So he is happy with the status quo
 of SCMI implementation.

Greg Edwards 11dd266637 audit: do not panic on invalid boot parameter
If you pass in an invalid audit boot parameter value, e.g. "audit=off",
the kernel panics very early in boot before the regular console is
initialized.  Unless you have earlyprintk enabled, there is no
indication of what the problem is on the console.

Convert the panic() calls to pr_err(), and leave auditing enabled if an
invalid parameter value was passed in.

Modify the parameter to also accept "on" or "off" as valid values, and
update the documentation accordingly.

This patch introduces kvm_para_has_hint() to query for hints about
the configuration of the guests.  The first hint KVM_HINTS_DEDICATED,
is set if the guest has dedicated physical CPUs for each vCPU (i.e.
pinning and no over-commitment).  This allows optimizing spinlocks
and tells the guest to avoid PV TLB flush.

Ken Hofsass 01643c51bf KVM: x86: KVM_CAP_SYNC_REGS
This commit implements an enhanced x86 version of S390
KVM_CAP_SYNC_REGS functionality. KVM_CAP_SYNC_REGS "allow[s]
userspace to access certain guest registers without having
to call SET/GET_*REGS”. This reduces ioctl overhead which
is particularly important when userspace is making synchronous
guest state modifications (e.g. when emulating and/or intercepting
instructions).

Originally implemented upstream for the S390, the x86 differences
follow:
- userspace can select the register sets to be synchronized with kvm_run
using bit-flags in the kvm_valid_registers and kvm_dirty_registers
fields.
- vcpu_events is available in addition to the regs and sregs register
sets.

Roman Kagan faeb7833ee kvm: x86: hyperv: guest->host event signaling via eventfd
In Hyper-V, the fast guest->host notification mechanism is the
SIGNAL_EVENT hypercall, with a single parameter of the connection ID to
signal.

Currently this hypercall incurs a user exit and requires the userspace
to decode the parameters and trigger the notification of the potentially
different I/O context.

To avoid the costly user exit, process this hypercall and signal the
corresponding eventfd in KVM, similar to ioeventfd.  The association
between the connection id and the eventfd is established via the newly
introduced KVM_HYPERV_EVENTFD ioctl, and maintained in an
(srcu-protected) IDR.

Add support for r8a7743. The Renesas RZ/G1M(R8A7743)PCIe controller
is identical to the R-Car Gen2 family.

No driver change is needed due to the fallback compatible value
"renesas,pcie-rcar-gen2".
Adding the SoC-specific compatible values here has three purposes:
1. Document which SoCs have this hardware module,
2. Allow checkpatch to validate compatible values.
3. Allow the driver to support SoC specific implementations in future

Masahiro Yamada 788778b0d2 mmc: tmio: deprecate "toshiba, mmc-wrprotect-disable" DT property
This property is equivalent to "disable-wp" defined in
Documentation/devicetree/bindings/mmc/mmc.txt

The TMIO MMC core calls mmc_of_parse(), and it sets
MMC_CAP2_NO_WRITE_PROTECT if "disable-wp" property is present.

We do not need a vendor-specific property to do the same thing.

Let's remove the description from the dt-binding to prevent new boards
from using it.

I am keeping the driver code for existing DT files, but added
comments that this is deprecated.

hash rather than just an L3 hash with the flow the label. To that end
add support to IPv6 for multipath hash policy similar to bf4e0a3db9
("net: ipv4: add support for ECMP hash policy choice"). The default
is still L3 which covers source and destination addresses along with
flow label and IPv6 protocol.

Daniel Axtens d02f51cbcf bpf: fix bpf_skb_adjust_net/bpf_skb_proto_xlat to deal with gso sctp skbs
SCTP GSO skbs have a gso_size of GSO_BY_FRAGS, so any sort of
unconditionally mangling of that will result in nonsense value
and would corrupt the skb later on.

Therefore, i) add two helpers skb_increase_gso_size() and
skb_decrease_gso_size() that would throw a one time warning and
bail out for such skbs and ii) refuse and return early with an
error in those BPF helpers that are affected. We do need to bail
out as early as possible from there before any changes on the
skb have been performed.

Niklas Cassel 928af22477 pinctrl: artpec6: dt: add smaller groups for uarts
Add group configuration for uarts that are cut down
variants, the standard being full, i.e. all signals,
flow control, i.e. rx/tx and cts/rts, and rx/tx only.

This allows us to be more precise in which pins we're
actually using.

Unfortunately the existing naming scheme leaves things
to be desired, e.g. uart3grp0 means RX/TX and CTS/RTS,
yet uart0grp0 means all pins.
Since the exising suffixes have different meaning for
different uarts, and the fact that we cannot change
the name of existing groups, makes it hard to use a
descriptive name for the newly added groups.

Alexandre Belloni ac75779b72 rtc: nvmem: allow registering the nvmem device before the rtc
Switch the parent of the nvmem device to the parent of the rtc device so it
can be registered before the RTC.

This is a small change in the ABI as the nvmem moves out of the
/sys/class/rtc/rtcX folder to be under the parent device folder (that is
where the previous nvram files where registered).

However, it is still available under its correct location,
/sys/bus/nvmem/devices which is the one that should be used by userspace
applications.

The other benefit is that the nvmem device can stay registered even if the
rtc registration fails. Or it is possible to not register the rtc if the
nvmem registration failed.

Finally, it makes a lot of sense for devices that actually have different
i2c or spi addresses for the RTC and the EEPROM. That is basically how it
would end up when using MFD or even completely separate devices.

SCP offers control and management of the core/cluster power states,
various power domain DVFS including the core/cluster, certain system
clocks configuration, thermal sensors and many others.

SCMI protocol is developed as better replacement to the existing SCPI
which is not flexible and easily extensible.

Dave Gerlach afe761f8d3 soc: ti: Add pm33xx driver for basic suspend support
AM335x and AM437x support various low power modes as documented
in section 8.1.4.3 of the AM335x Technical Reference Manual and
section 6.4.3 of the AM437x Technical Reference Manual.

DeepSleep0 mode offers the lowest power mode with limited
wakeup sources without a system reboot and is mapped as
the suspend state in the kernel. In this state, MPU and
PER domains are turned off with the internal RAM held in
retention to facilitate the resume process. As part of
the boot process, the assembly code is copied over to OCMCRAM
so it can be executed to turn of the EMIF and put DDR into self
refresh.

Both platforms have a Cortex-M3 (WKUP_M3) which assists the MPU
in DeepSleep0 entry and exit. WKUP_M3 takes care
of the clockdomain and powerdomain transitions based on the
intended low power state. MPU needs to load the appropriate
WKUP_M3 binary onto the WKUP_M3 memory space before it can
leverage any of the PM features like DeepSleep. This loading
is handled by the remoteproc driver wkup_m3_rproc.

Communication with the WKUP_M3 is handled by a wkup_m3_ipc
driver that exposes the specific PM functionality to be used
the PM code.

In the current implementation when the suspend process
is initiated, MPU interrupts the WKUP_M3 to let it know about
the intent of entering DeepSleep0 and waits for an ACK. When
the ACK is received MPU continues with its suspend process
to suspend all the drivers and then jumps to assembly in
OCMC RAM. The assembly code puts the external RAM in self-refresh
mode, gates the MPU clock, and then finally executes the WFI
instruction. Execution of the WFI instruction with MPU clock gated
triggers another interrupt to the WKUP_M3 which then continues
with the power down sequence wherein the clockdomain and
powerdomain transition takes place. As part of the sleep sequence,
WKUP_M3 unmasks the interrupt lines for the wakeup sources. WFI
execution on WKUP_M3 causes the hardware to disable the main
oscillator of the SoC and from here system remains in sleep state
until a wake source brings the system into resume path.

When a wakeup event occurs, WKUP_M3 starts the power-up
sequence by switching on the power domains and finally
enabling the clock to MPU. Since the MPU gets powered down
as part of the sleep sequence in the resume path ROM code
starts executing. The ROM code detects a wakeup from sleep
and then jumps to the resume location in OCMC which was
populated in one of the IPC registers as part of the suspend
sequence.

Code is based on work by Vaibhav Bedia.

Jan H. Schönherr ef61f8a340 x86/boot/e820: Implement a range manipulation operator
Add a more versatile memmap= operator, which -- in addition to all the
things that were possible before -- allows you to:

- redeclare existing ranges -- before, you were limited to adding ranges;
- drop any range -- like a mem= for any location;
- use any e820 memory type -- not just some predefined ones.

The syntax is:

  memmap=<size>%<offset>-<oldtype>+<newtype>

Size and offset work as usual. The "-<oldtype>" and "+<newtype>" are
optional and their existence determine the behavior: The command
works on the specified range of memory limited to type <oldtype>
(if specified). This memory is then configured to show up as <newtype>.
If <newtype> is not specified, the memory is removed from the e820 map.

 "A small set of fixes:

   - UAPI data type correction for hyperv

   - correct the cpu cores field in /proc/cpuinfo on CPU hotplug

   - return proper error code in the resctrl file system failure path to
     avoid silent subsequent failures

   - correct a subtle accounting issue in the new vector allocation code
     which went unnoticed for a while and caused suspend/resume
     failures"

Radim Krčmář fe2a3027e7 KVM: x86: fix backward migration with async_PF
Guests on new hypersiors might set KVM_ASYNC_PF_DELIVERY_AS_PF_VMEXIT
bit when enabling async_PF, but this bit is reserved on old hypervisors,
which results in a failure upon migration.

To avoid breaking different cases, we are checking for CPUID feature bit
before enabling the feature and nothing else.

Merge tag 'drm-fixes-for-v4.16-rc3' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "A bunch of fixes for rc3:

  Exynos:
   - fixes for using monotonic timestamps
   - register definitions
   - removal of unused file

  ipu-v3L
   - minor changes
   - make some register arrays const+static
   - fix some leaks

  meson:
   - fix for vsync

  atomic:
   - fix for memory leak

  EDID parser:
   - add quirks for some more non-desktop devices
   - 6-bit panel fix.

  drm_mm:
   - fix a bug in the core drm mm hole handling

  cirrus:
   - fix lut loading regression

  Lastly there is a deadlock fix around runtime suspend for secondary
  GPUs.

  There was a deadlock between one thread trying to wait for a workqueue
  job to finish in the runtime suspend path, and the workqueue job it
  was waiting for in turn waiting for a runtime_get_sync to return.

  The fixes avoids it by not doing the runtime sync in the workqueue as
  then we always wait for all those tasks to complete before we runtime
  suspend"
