6cdebf62a1 spi: Updates for v6.9
This release sees some exciting changes from David Lechner which
 implements some optimisations that have been talked about for a long
 time which allows client drivers to pre-prepare SPI messages for
 repeated or low latency use.  This lets us move work out of latency
 sensitive paths and avoid repeating work for frequently performed
 operations.  As well as being useful in itself this will also be used in
 future to allow controllers to directly trigger SPI operations (eg, from
 interrupts).
 
 Otherwise this release has mostly been focused on cleanups, plus a
 couple of new devices:
 
  - Support for pre-optimising messages.
  - A big set of updates from Uwe Kleine-König moving drivers to use APIs
    with more modern terminology for controllers.
  - Major overhaul of the s3c64xx driver.
  - Support for Google GS101 and Samsung Exynos850.

ca7e917769 Rework of APIC enumeration and topology evaluation:
The current implementation has a couple of shortcomings:
 
   - It fails to handle hybrid systems correctly.
 
   - The APIC registration code which handles CPU number assignents is in
     the middle of the APIC code and detached from the topology evaluation.
 
   - The various mechanisms which enumerate APICs, ACPI, MPPARSE and guest
     specific ones, tweak global variables as they see fit or in case of
     XENPV just hack around the generic mechanisms completely.
 
   - The CPUID topology evaluation code is sprinkled all over the vendor
     code and reevaluates global variables on every hotplug operation.
 
   - There is no way to analyze topology on the boot CPU before bringing up
     the APs. This causes problems for infrastructure like PERF which needs
     to size certain aspects upfront or could be simplified if that would be
     possible.
 
   - The APIC admission and CPU number association logic is incomprehensible
     and overly complex and needs to be kept around after boot instead of
     completing this right after the APIC enumeration.
 
 This update addresses these shortcomings with the following changes:
 
   - Rework the CPUID evaluation code so it is common for all vendors and
     provides information about the APIC ID segments in a uniform way
     independent of the number of segments (Thread, Core, Module, ..., Die,
     Package) so that this information can be computed instead of rewriting
     global variables of dubious value over and over.
 
   - A few cleanups and simplifcations of the APIC, IO/APIC and related
     interfaces to prepare for the topology evaluation changes.
 
   - Seperation of the parser stages so the early evaluation which tries to
     find the APIC address can be seperately overridden from the late
     evaluation which enumerates and registers the local APIC as further
     preparation for sanitizing the topology evaluation.
 
   - A new registration and admission logic which
 
      - encapsulates the inner workings so that parsers and guest logic
        cannot longer fiddle in it
 
      - uses the APIC ID segments to build topology bitmaps at registration
        time
 
      - provides a sane admission logic
 
      - allows to detect the crash kernel case, where CPU0 does not run on
        the real BSP, automatically. This is required to prevent sending
        INIT/SIPI sequences to the real BSP which would reset the whole
        machine. This was so far handled by a tedious command line
        parameter, which does not even work in nested crash scenarios.
 
      - Associates CPU number after the enumeration completed and prevents
        the late registration of APICs, which was somehow tolerated before.
 
   - Converting all parsers and guest enumeration mechanisms over to the
     new interfaces.
 
     This allows to get rid of all global variable tweaking from the parsers
     and enumeration mechanisms and sanitizes the XEN[PV] handling so it can
     use CPUID evaluation for the first time.
 
   - Mopping up existing sins by taking the information from the APIC ID
     segment bitmaps.
 
     This evaluates hybrid systems correctly on the boot CPU and allows for
     cleanups and fixes in the related drivers, e.g. PERF.
 
 The series has been extensively tested and the minimal late fallout due to
 a broken ACPI/MADT table has been addressed by tightening the admission
 logic further.

aec7d25b49 platform/x86: p2sb: On Goldmont only cache P2SB and SPI devfn BAR
On Goldmont p2sb_bar() only ever gets called for 2 devices, the actual P2SB
devfn 13,0 and the SPI controller which is part of the P2SB, devfn 13,2.

But the current p2sb code tries to cache BAR0 info for all of
devfn 13,0 to 13,7 . This involves calling pci_scan_single_device()
for device 13 functions 0-7 and the hw does not seem to like
pci_scan_single_device() getting called for some of the other hidden
devices. E.g. on an ASUS VivoBook D540NV-GQ065T this leads to continuous
ACPI errors leading to high CPU usage.

Fix this by only caching BAR0 info and thus only calling
pci_scan_single_device() for the P2SB and the SPI controller.

Randomly a Lenovo Z13 will trigger a kernel warning traceback from this
condition:

```
if (WARN_ON((profile < 0) || (profile >= ARRAY_SIZE(profile_names))))
```

This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.

Catch this situation and avoid updating the profile. Also log this into
dynamic debugging in case any other modes should be added in the future.

Commit 14c200b7ca ("platform/x86: intel-vbtn: Fix missing

1. The ThinkPad will wake up immediately from suspend
2. When put in tablet mode SW_TABLET_MODE reverts to 0 after about 1 second

Both these issues are caused by the "VBDL" ACPI method call added
at the end of the notify_handler.

And it never became entirely clear if this call is even necessary to fix
the issue of missing tablet-mode-switch events on the Dell Inspiron 7352.

Drop the "VBDL" ACPI method call again to fix the 2 issues this is
causing on the ThinkPad X1 Tablet Gen2.

dc5afd720f platform/x86: Add new get_serdev_controller() helper
In some cases UART attached devices which require an in kernel driver,
e.g. UART attached Bluetooth HCIs are described in the ACPI tables
by an ACPI device with a broken or missing UartSerialBusV2() resource.

This causes the kernel to create a /dev/ttyS# char-device for the UART
instead of creating an in kernel serdev-controller + serdev-device pair
for the in kernel driver.

The quirk handling in acpi_quirk_skip_serdev_enumeration() makes the kernel
create a serdev-controller device for these UARTs instead of a /dev/ttyS#.

Instantiating the actual serdev-device to bind to is up to pdx86 code,
so far this was handled by the x86-android-tablets code. But since
commit b286f4e87e ("serial: core: Move tty and serdev to be children of
serial core port device") the serdev-controller device has moved in the
device hierarchy from (e.g.) /sys/devices/pci0000:00/8086228A:00/serial0 to
/sys/devices/pci0000:00/8086228A:00/8086228A:00:0/8086228A:00:0.0/serial0 .

This makes this a bit trickier to do and another driver is in the works
which will also need this functionality.

Add a new helper to get the serdev-controller device, so that the new
code for this can be shared.

After commit 4014ae236b ("platform/x86: x86-android-tablets: Stop using
gpiolib private APIs") the touchscreen in the keyboard half of
the Lenovo Yogabook1 X90 stopped working with the following error:

 Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO

The problem is that when getting the IRQ for instantiated i2c_client-s
from a GPIO (rather then using an IRQ directly from the IOAPIC),
x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows
other drivers from requesting it. Normally this is a good thing, but
the goodix touchscreen also uses the IRQ as an output during reset
to select which of its 2 possible I2C addresses should be used.

Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this
and release the GPIO after getting the IRQ in this special case.

dbcbfd662a platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI names
On some devices the ACPI name of the touchscreen is e.g. either
MSSL1680:00 or MSSL1680:01 depending on the BIOS version.

This happens for example on the "Chuwi Hi8 Air" tablet where the initial
commit's ts_data uses "MSSL1680:00" but the tablets from the github issue
and linux-hardware.org probe linked below both use "MSSL1680:01".

Replace the strcmp() match on ts_data->acpi_name with a strstarts()
check to allow using a partial match on just the ACPI HID of "MSSL1680"
and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly
to fix the touchscreen not working on models where it is "MSSL1680:01".

Note this drops the length check for I2C_NAME_SIZE. This never was
necessary since the ACPI names used are never more then 11 chars and
I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long
before reaching I2C_NAME_SIZE.

8cbc756b80 platform/mellanox: mlxbf-tmfifo: Drop Tx network packet when Tx TmFIFO is full
Starting from Linux 5.16 kernel, Tx timeout mechanism was added
in the virtio_net driver which prints the "Tx timeout" warning
message when a packet stays in Tx queue for too long. Below is an
example of the reported message:

"[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on
queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since
last trans: 3079892256".

This issue could happen when external host driver which drains the
FIFO is restared, stopped or upgraded. To avoid such confusing
"Tx timeout" messages, this commit adds logic to drop the outstanding
Tx packet if it's not able to transmit in two seconds due to Tx FIFO
full, which can be considered as congestion or out-of-resource drop.

This commit also handles the special case that the packet is half-
transmitted into the Tx FIFO. In such case, the packet is discarded
with remaining length stored in vring->rem_padding. So paddings with
zeros can be sent out when Tx space is available to maintain the
integrity of the packet format. The padded packet will be dropped on
the receiving side.

5913320eb0 platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe
p2sb_bar() unhides P2SB device to get resources from the device. It
guards the operation by locking pci_rescan_remove_lock so that parallel
rescans do not find the P2SB device. However, this lock causes deadlock
when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan
locks pci_rescan_remove_lock and probes PCI devices. When PCI devices
call p2sb_bar() during probe, it locks pci_rescan_remove_lock again.
Hence the deadlock.

To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar().
Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources()
for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(),
refer the cache and return to the caller.

Before operating the device at P2SB DEVFN for resource cache, check
that its device class is PCI_CLASS_MEMORY_OTHER 0x0580 that PCH
specifications define. This avoids unexpected operation to other devices
at the same DEVFN.

416de0246f platform/x86: intel-uncore-freq: Fix types in sysfs callbacks
When booting a kernel with CONFIG_CFI_CLANG, there is a CFI failure when
accessing any of the values under
/sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00:

  $ cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/max_freq_khz
  fish: Job 1, 'cat /sys/devices/system/cpu/int…' terminated by signal SIGSEGV (Address boundary error)

  $ sudo dmesg &| grep 'CFI failure'
  [  170.953925] CFI failure at kobj_attr_show+0x19/0x30 (target: show_max_freq_khz+0x0/0xc0 [intel_uncore_frequency_common]; expected type: 0xd34078c5

The sysfs callback functions such as show_domain_id() are written as if
they are going to be called by dev_attr_show() but as the above message
shows, they are instead called by kobj_attr_show(). kCFI checks that the
destination of an indirect jump has the exact same type as the prototype
of the function pointer it is called through and fails when they do not.

These callbacks are called through kobj_attr_show() because
uncore_root_kobj was initialized with kobject_create_and_add(), which
means uncore_root_kobj has a ->sysfs_ops of kobj_sysfs_ops from
kobject_create(), which uses kobj_attr_show() as its ->show() value.

The only reason there has not been a more noticeable problem until this
point is that 'struct kobj_attribute' and 'struct device_attribute' have
the same layout, so getting the callback from container_of() works the
same with either value.

Change all the callbacks and their uses to be compatible with
kobj_attr_show() and kobj_attr_store(), which resolves the kCFI failure
and allows the sysfs files to work properly.

29e473f4b5 platform/x86: wmi: Fix notify callback locking
When an legacy WMI event handler is removed, an WMI event could
have called the handler just before it was removed, meaning the
handler could still be running after wmi_remove_notify_handler()
returns.
Something similar could also happens when using the WMI bus, as
the WMI core might still call the notify() callback from an WMI
driver even if its remove() callback was just called.

Fix this by introducing a rw semaphore which ensures that the
event state of a WMI device does not change while the WMI core
is handling an event for it.

Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

3ea7f59af8 platform/x86: wmi: Decouple legacy WMI notify handlers from wmi_block_list
Until now, legacy WMI notify handler functions where using the
wmi_block_list, which did no refcounting on the returned WMI device.
This meant that the WMI device could disappear at any moment,
potentially leading to various errors.
Fix this by using bus_find_device() which returns an actual
reference to the found WMI device.

Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

3d8a29fec2 platform/x86: wmi: Return immediately if an suitable WMI event is found
Commit 58f6425eb9 ("WMI: Cater for multiple events with same GUID")
allowed legacy WMI notify handlers to be installed for multiple WMI
devices with the same GUID.
However this is useless since the legacy GUID-based interface is
blacklisted from seeing WMI devices with duplicated GUIDs.

Return immediately if a suitable WMI event is found in
wmi_install/remove_notify_handler() since searching for other suitable
events is pointless.

Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

6ba7843b59 platform/x86: wmi: Fix error handling in legacy WMI notify handler functions
When wmi_install_notify_handler()/wmi_remove_notify_handler() are
unable to enable/disable the WMI device, they unconditionally return
an error to the caller.
When registering legacy WMI notify handlers, this means that the
callback remains registered despite wmi_install_notify_handler()
having returned an error.
When removing legacy WMI notify handlers, this means that the
callback is removed despite wmi_remove_notify_handler() having
returned an error.

Fix this by only warning when the WMI device could not be enabled.
This behaviour matches the bus-based WMI interface.

Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

42bff4d0f9 pwm: Changes for v6.8-rc1
This contains a bunch of cleanups and simplifications across the board,
 as well as a number of small fixes.
 
 Perhaps the most notable change here is the addition of an API that
 allows PWMs to be used in atomic contexts, which is useful when time-
 critical operations are involved, such as using a PWM to generate IR
 signals.
 
 Finally, I have decided to step down as PWM subsystem maintainer. Due to
 other responsibilities I have lately not been able to find the time that
 the subsystem deserves and Uwe, who has been helping out a lot for the
 past few years and has many things planned for the future, has kindly
 volunteered to take over. I have no doubt that he will be a suitable
 replacement.

5b9b41617b Another moderately busy cycle for documentation, including:
- The minimum Sphinx requirement has been raised to 2.4.4, following a
   warning that was added in 6.2.
 
 - Some reworking of the Documentation/process front page to, hopefully,
   make it more useful.
 
 - Various kernel-doc tweaks to, for example, make it deal properly with
   __counted_by annotations.
 
 - We have also restored a warning for documentation of nonexistent
   structure members that disappeared a while back.  That had the delightful
   consequence of adding some 600 warnings to the docs build.  A sustained
   effort by Randy, Vegard, and myself has addressed almost all of those,
   bringing the documentation back into sync with the code.  The fixes are
   going through the appropriate maintainer trees.
 
 - Various improvements to the HTML rendered docs, including automatic links
   to Git revisions and a nice new pulldown to make translations easy to
   access.
 
 - Speaking of translations, more of those for Spanish and Chinese.
 
 ...plus the usual stream of documentation updates and typo fixes.

bd012f3a5b ACPI updates for 6.8-rc1
- Add CSI-2 and DisCo for Imaging support to the ACPI device
    enumeration code (Sakari Ailus, Rafael J. Wysocki).
 
  - Adjust the cpufreq thermal reduction algorithm in the ACPI processor
    driver for Tegra241 (Srikar Srimath Tirumala, Arnd Bergmann).
 
  - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki).
 
  - Switch over ACPI to using a threaded interrupt handler for the
    SCI (Rafael J. Wysocki).
 
  - Allow ACPI Notify () handlers to run on all CPUs and clean up the
    ACPI interface for deferred events processing (Rafael J. Wysocki).
 
  - Switch over the ACPI EC driver to using a threaded handler for the
    dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki).
 
  - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock to
    keep local interrupts on (Rafael J. Wysocki).
 
  - Adjust the USB4 _OSC handshake to correctly handle cases in which
    certain types of OS control are denied by the platform (Mika
    Westerberg).
 
  - Correct and clean up the generic function for parsing ACPI data-only
    tables with array structure (Yuntao Wang).
 
  - Modify acpi_dev_uid_match() to support different types of its second
    argument and adjust its users accordingly (Raag Jadav).
 
  - Clean up code related to acpi_evaluate_reference() and ACPI device
    lists (Rafael J. Wysocki).
 
  - Use generic ACPI helpers for evaluating trip point temperature
    objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
    Bergmann).
 
  - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
    zone driver (Jeff Brasen).
 
  - Modify the ACPI LPIT table handling code to avoid u32 multiplication
    overflows in state residency computations (Nikita Kiryushin).
 
  - Drop an unused helper function from the ACPI backlight (video) driver
    and add a clarifying comment to it (Hans de Goede).
 
  - Update the ACPI backlight driver to avoid using uninitialized memory
    in some cases (Nikita Kiryushin).
 
  - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
    Qiu).
 
  - Add support for vendor-defined error types to the ACPI APEI error
    injection code (Avadhut Naik).
 
  - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous memory
    failure events, so they are handled differently from the asynchronous
    ones (Shuai Xue).
 
  - Fix NULL pointer dereference check in the ACPI extlog driver (Prarit
    Bhargava).
 
  - Adjust the ACPI extlog driver to clear the Extended Error Log status
    when RAS_CEC handled the error (Tony Luck).
 
  - Add IRQ override quirks for some Infinity laptops and for TongFang
    GMxXGxx (David McFarland, Hans de Goede).
 
  - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not
    the same as one of the real pxm values (Yuntao Wang).
 
  - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
    driver so as to prevent miscalculation of the values in the clock
    divider (Andy Shevchenko).
 
  - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
    from complaining during documentation builds (Randy Dunlap).
 
  - Make the ACPI button driver send wakeup key events to user space in
    addition to power button events on systems that can be woken up by
    the power button (Ken Xue).
 
  - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
    structure field (Dmitry Antipov).

  former is not used) which essentially allows all ACPI code to run with
  local interrupts enabled. That should improve responsiveness
  significantly on systems where multiple GPEs are enabled and the
  handling of one SCI involves many I/O address space accesses which
  previously had to be carried out in one go with disabled interrupts on
  the local CPU.

  Apart from the above, the ACPI thermal zone driver will use the
  Thermal fast Sampling Period (_TFP) object if available, which should
  allow temperature changes to be followed more accurately on some
  systems, the ACPI Notify () handlers can run on all CPUs (not just on
  CPU0), which should generally speed up the processing of events
  signaled through the ACPI SCI, and the ACPI power button driver will
  trigger wakeup key events via the input subsystem (on systems where it
  is a system wakeup device)

  In addition to that, there are the usual bunch of fixes and cleanups.

  Specifics:

   - Add CSI-2 and DisCo for Imaging support to the ACPI device
     enumeration code (Sakari Ailus, Rafael J. Wysocki)

   - Adjust the cpufreq thermal reduction algorithm in the ACPI
     processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
     Bergmann)

   - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)

   - Switch over ACPI to using a threaded interrupt handler for the SCI
     (Rafael J. Wysocki)

   - Allow ACPI Notify () handlers to run on all CPUs and clean up the
     ACPI interface for deferred events processing (Rafael J. Wysocki)

   - Switch over the ACPI EC driver to using a threaded handler for the
     dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)

   - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
     to keep local interrupts on (Rafael J. Wysocki)

   - Adjust the USB4 _OSC handshake to correctly handle cases in which
     certain types of OS control are denied by the platform (Mika
     Westerberg)

   - Correct and clean up the generic function for parsing ACPI
     data-only tables with array structure (Yuntao Wang)

   - Modify acpi_dev_uid_match() to support different types of its
     second argument and adjust its users accordingly (Raag Jadav)

   - Clean up code related to acpi_evaluate_reference() and ACPI device
     lists (Rafael J. Wysocki)

   - Use generic ACPI helpers for evaluating trip point temperature
     objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
     Bergmann)

   - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
     zone driver (Jeff Brasen)

   - Modify the ACPI LPIT table handling code to avoid u32
     multiplication overflows in state residency computations (Nikita
     Kiryushin)

   - Drop an unused helper function from the ACPI backlight (video)
     driver and add a clarifying comment to it (Hans de Goede)

   - Update the ACPI backlight driver to avoid using uninitialized
     memory in some cases (Nikita Kiryushin)

   - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
     Qiu)

   - Add support for vendor-defined error types to the ACPI APEI error
     injection code (Avadhut Naik)

   - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
     memory failure events, so they are handled differently from the
     asynchronous ones (Shuai Xue)

   - Fix NULL pointer dereference check in the ACPI extlog driver
     (Prarit Bhargava)

   - Adjust the ACPI extlog driver to clear the Extended Error Log
     status when RAS_CEC handled the error (Tony Luck)

   - Add IRQ override quirks for some Infinity laptops and for TongFang
     GMxXGxx (David McFarland, Hans de Goede)

   - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
     not the same as one of the real pxm values (Yuntao Wang)

   - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
     driver so as to prevent miscalculation of the values in the clock
     divider (Andy Shevchenko)

   - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
     from complaining during documentation builds (Randy Dunlap)

   - Make the ACPI button driver send wakeup key events to user space in
     addition to power button events on systems that can be woken up by
     the power button (Ken Xue)

   - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
     structure field (Dmitry Antipov)"

9f2a635235 Quite a lot of kexec work this time around. Many singleton patches in
many places.  The notable patch series are:
 
 - nilfs2 folio conversion from Matthew Wilcox in "nilfs2: Folio
   conversions for file paths".
 
 - Additional nilfs2 folio conversion from Ryusuke Konishi in "nilfs2:
   Folio conversions for directory paths".
 
 - IA64 remnant removal in Heiko Carstens's "Remove unused code after
   IA-64 removal".
 
 - Arnd Bergmann has enabled the -Wmissing-prototypes warning everywhere
   in "Treewide: enable -Wmissing-prototypes".  This had some followup
   fixes:
 
   - Nathan Chancellor has cleaned up the hexagon build in the series
     "hexagon: Fix up instances of -Wmissing-prototypes".
 
   - Nathan also addressed some s390 warnings in "s390: A couple of
     fixes for -Wmissing-prototypes".
 
   - Arnd Bergmann addresses the same warnings for MIPS in his series
     "mips: address -Wmissing-prototypes warnings".
 
 - Baoquan He has made kexec_file operate in a top-down-fitting manner
   similar to kexec_load in the series "kexec_file: Load kernel at top of
   system RAM if required"
 
 - Baoquan He has also added the self-explanatory "kexec_file: print out
   debugging message if required".
 
 - Some checkstack maintenance work from Tiezhu Yang in the series
   "Modify some code about checkstack".
 
 - Douglas Anderson has disentangled the watchdog code's logging when
   multiple reports are occurring simultaneously.  The series is "watchdog:
   Better handling of concurrent lockups".
 
 - Yuntao Wang has contributed some maintenance work on the crash code in
   "crash: Some cleanups and fixes".
