04d29e3609 - Untangle the Retbleed from the ITS mitigation on Intel. Allow for ITS 
to enable stuffing independently from Retbleed, do some cleanups to
   simplify and streamline the code
 
 - Simplify SRSO and make mitigation types selection more versatile
   depending on the Retbleed mitigation selection. Simplify code some
 
 - Add the second part of the attack vector controls which provide a lot
   friendlier user interface to the speculation mitigations than
   selecting each one by one as it is now.
 
   Instead, the selection of whole attack vectors which are relevant to
   the system in use can be done and protection against only those
   vectors is enabled, thus giving back some performance to the users

78bb43e51b Updates for the generic entry code: 
- Split the code into syscall and exception/interrupt parts to ease the
     conversion of ARM[64] to the generic entry infrastructure
 
   - Extend syscall user dispatching to support a single intercepted range
     instead of the default single non-intercepted range. That allows
     monitoring/analysis of a specific executable range, e.g. a library, and

02dc9d15d7 Updates for the timekeeping and VDSO code: 
- Introduce support for auxiliary timekeepers
 
       PTP clocks can be disconnected from the universal CLOCK_TAI reality
       for various reasons including regularatory requirements for
       functional safety redundancy.
 
       The kernel so far only supports a single notion of time, which means
       that all clocks are correlated in frequency and only differ by
       offset to each other.
 
       Access to non-correlated PTP clocks has been available so far only
       through the file descriptor based "POSIX clock IDs", which are
       subject to locking and have to go all the way out to the hardware.
 
       The access is not only horribly slow, as it has to go all the way out
       to the NIC/PTP hardware, but that also prevents the kernel to read
       the time of such clocks e.g. from the network stack, where it is
       required for TSN networking both on the transmit and receive side
       unless the hardware provides offloading.
 
       The auxiliary clocks provide a mechanism to support arbitrary clocks
       which are not correlated to the system clock. This is not restricted
       to the PTP use case on purpose as there is no kernel side association
       of these clocks to a particular PTP device because that's a pure user
       space configuration decision. Having them independent allows to
       utilize them for other purposes and also enables them to be tested
       without hardware dependencies.
 
       To avoid pointless overhead these clocks have to be enabled
       individualy via a new sysfs interface to reduce the overhead to a
       single compare in the hotpath if they are enabled at the Kconfig
       level at all.
 
       These clocks utilize the existing timekeeping/NTP infrastructures,
       which has been made possible over the recent releases by incrementaly
       converting these infrastructures over from a single static instance
       to a multi-instance pointer based implementation without any
       performance regression reported.
 
       The auxiliary clocks provide the same "emulation" of a "correct"
       clock as the existing CLOCK_* variants do with an independent
       instance of data and provide the same steering mechanism through the
       existing sys_clock_adjtime() interface, which has been confirmed to
       work by the chronyd(8) maintainer.
 
       That allows to provide lockless kernel internal and VDSO support so
       that applications and kernel internal functionalities can access
       these clocks without restrictions and at the same performance as the
       existing system clocks.
 
   - Avoid double notifications in the adjtimex() syscall. Not a big issue,
     but a trivial to avoid latency source.

0b29600a30 Updates for interrupt chip drivers: 
- Add support of forced affinity setting to yet offline CPUs for the
    MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
    during the early bringup phase of a secondary CPU in the hotplug code
    before the CPU is set online and interrupts are enabled.\
 
  - Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
    interrupt chip
 
  - Make the interrupt routing to RISV-V harts specification compliant so it
    supports arbitrary hart indices
 
  - Add a command line parameter and related handling to disable the generic
    RISCV IMSIC mechanism on platforms which use a trap-emulated IMSIC.
    Unfortunatly this is required because there is no mechanism available to
    discover this programatically.
 
  - Enable wakeup sources on the Renesas RZV2H driver
 
  - Convert interrupt chip drivers, which use a open coded variant of
    msi_create_parent_irq_domain() to use the new functionality
 
  - Convert interrupt chip drivers, which use the old style two level
    implementation of MSI support over to the MSI parent mechanism to
    prepare for removing at least one of the three PCI/MSI backend variants.

Pull interrupt chip driver updates from Thomas Gleixner:

 - Add support of forced affinity setting to yet offline CPUs for the
   MIPS-GIC to ensure that the affinity of per CPU interrupts can be set
   during the early bringup phase of a secondary CPU in the hotplug code
   before the CPU is set online and interrupts are enabled

 - Add support for the MIPS (RISC-V !?!?) P8700 SoC in the ACLINT_SSWI
   interrupt chip

 - Make the interrupt routing to RISV-V harts specification compliant so
   it supports arbitrary hart indices

 - Add a command line parameter and related handling to disable the
   generic RISCV IMSIC mechanism on platforms which use a trap-emulated
   IMSIC. Unfortunatly this is required because there is no mechanism
   available to discover this programatically.

 - Enable wakeup sources on the Renesas RZV2H driver

 - Convert interrupt chip drivers, which use a open coded variant of
   msi_create_parent_irq_domain() to use the new functionality

 - Convert interrupt chip drivers, which use the old style two level
   implementation of MSI support over to the MSI parent mechanism to
   prepare for removing at least one of the three PCI/MSI backend
   variants.

 - The usual cleanups and improvements all over the place

dba3ec9f2a Updates for the interrupt core subsystem: 
- Prevent a interrupt migration related live lock in handle_edge_irq()
 
     If the interrupt affinity is moved to a new target CPU and the
     interrupt is currently handled on the previous target CPU for edge type
     interrupts the handler might get stuck on the previous target for a
     long time, which causes both involved CPUs to waste cycles and
     eventually run into a soft-lockup situation.
 
     Solve this by checking whether the interrupt is redirected to a new
     target CPU and if the interrupt is handled on that new target CPU, busy
     wait for completion instead of masking it and sending the pending but
     which would cause the old CPU to re-run the handler and in the worst
     case repeating this excercise for a long time.
 
     This only works on architectures which use single CPU interrupt
     targets, but that's so far the only ones where this behaviour has been
     observed.
 
   - Add a kunit test for interrupt disable depth counts
 
     The nested interrupt disable depth has been an issue in the past
     especially vs. free_irq(), interrupt shutdown and CPU hotplug and their
     interactions. The test exercises the combinations of these scenarios
     and checks for correctness.

4df9c0a246 soc: new SoC support for 6.17 
These five newly supported chips come with both devicetree descriptions
 and the changes to wire them up to the build system for easier bisection.
 
 The chips in question are:
 
  - Marvell PXA1908 was the first 64-bit mobile phone chip from Marvell
    in the product line that started with the Digital StrongARM SA1100
    based PDAs and continued with the Intel PXA2xx that dominated early
    smartphones. This one only made it only into a few products before the
    entire product line was cut in 2015.
 
  - The QiLai SoC is made by RISC-V core designer Andes Technologies
    and is in the 'Voyager' reference board in MicroATX form factor.
    It uses four in-order AX45MP cores, which is the midrange product
    from Andes.
 
  - CIX P1 is one of the few Arm chips designed for small workstations,
    and this one uses 12 Cortex-A720/A520 cores, making it also one
    of the only ARMv9.2 machines that one can but at the moment.
 
  - Axiado AX3000 is an embedded chip with relative small Cortex-A53
    CPU cores described as a "Trusted Control/Compute Unit" that can
    be used as a BMC in servers. In addition to the usual I/O, this one
    comes with 10GBit ethernet and and a 4TOPS NPU.
 
  - Sophgo SG2000 is an embedded chip that comes with both RISC-V
    and Arm cores that can run Linux. This was already supported for
    RISC-V but now it also works on Arm
 
 One more chip, the Black Sesame C1200 did not make it in tirm for the
 merge window.

0f46f50845 soc: driver updates for 6.17 
Changes are all over the place, but very little sticks out as
 noteworthy.
 
 There is a new misc driver for the Raspberry Pi 5's RP1 multifunction
 I/O chip, along with hooking it up to the pinctrl and clk frameworks.
 
 The reset controller and memory subsystems have mainly small updates,
 but there are two new reset drivers for the K230 and VC1800B SoCs,
 and new memory driver support for Tegra264.
 
 The ARM SMCCC and SCMI firmware drivers gain a few more features that
 should help them be supported across more environments. Similarly,
 the SoC specific firmware on Tegra and Qualcomm get minor enhancements
 and chip support.
 
 In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an
 overhaul for code robustness, the Tegra and Qualcomm and NXP drivers
 grow to support more chips, while the Hisilicon, Mediatek and Renesas
 drivers see mostly janitorial fixes.

115e74a29b soc: dt changes for 6.17 
There are a few new variants of existing chips:
 
  - mt6572 is an older mobile phone chip from mediatek that was
    extremely popular a decade ago but never got upstreamed until now.
 
  - exynos2200 is a recent high-end mobile phone chip used in a
    few Samsung phones like the Galaxy S22
 
  - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
    (R8A779H0) and used in automotive applications
 
  - Tegra264 is a new chip from NVIDIA, but support is fairly minimal
    for now, and not much information is public about it.
 
 There are five more chips in a separate branch, as those are new
 chip families that I merged along with the necessary infrastructure.
 
 New board support is not that exciting, with a total of 33 newly
 added machines here:
 
  - Evaluation platforms for the chips above, plus TI am62d2 and
    Sophgo sg2042.
 
  - Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
    plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
    imx95.
 
  - Two newly added ASPEED BMC based motherboards, and one that got
    removed
 
  - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
    msm8976 SoCs
 
  - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
 
  - A set-top box based on Amlogic meson-gxm.
 
 Updates for existing machines are spread over all the above families.
 One notable change here is support for the RP1 I/O chip used in
 Raspberry Pi 5.

4eee1520ea USB / Thunderbolt changes for 6.17-rc1 
Here is the big set of USB and Thunderbolt driver changes for 6.17-rc1.
 
 Lots of little things in here, mostly all small cleanups and updates, no
 major new features this development cycle.  Stuff included in here is:
   - xhci minor tweaks for error handling
   - typec minor updates and a driver update
   - gadget driver api cleanups
   - unused function removals
   - unbind memory leak fixes
   - a few new device ids added
   - a few new devices supported for some drivers
   - other minor cleanups and changes
 
 All of these have been in linux-next with no reported issues, with the
 leak fixes being in the shortest amount of time, but they are "obviously
 correct" :)

1641684528 Staging changes for 6.17-rc1 
Here is the "big" set of staging driver changes for 6.17-rc1.  That's in
 quotes as it really isn't all that big of a set of changes this
 development cycle at all.
 
 Major things that stand out are:
   - gpib cleanups and tweaks with the majority of the big issues now
     taken care of.  Odds are it will move out of staging/ in the next
     merge window if all goes well.
   - more constant cleanups and layer removals from the rtl8723bs driver.
     It's amazing how many layers deep they really are, all cleanups here
     are great to see
   - axis-fifo sysfs api removed and debugfs api added.  The sysfs api
     didn't work at all so obviously no one was using it.  Add the same
     information into debugfs as that's the proper place for it, and make
     it actually work.
   - Remaining changes is lots of small checkpatch cleanups, most of
     which seem to have come from a Debconf session where people were
     encouraged to submit their first kernel patch, a nice thing to see
     happen again.
 
 All of these have been in linux-next with no reported issues.

f38b751290 pwm: Changes for v6.17-rc1 
Apart from the usual mix of new drivers (pwm-argon-fan-hat), adding
 support for variants to existing drivers, minor improvements to both
 drivers and docs, device tree documenation updates, the noteworthy
 changes are:
 
  - A pull of pm-runtime-6.17-rc1 to make it possible to apply
    a582469541 ("pwm: img: Remove redundant pm_runtime_mark_last_busy()
    calls"). Note this updates the base for my tree to 6.16-rc2.
 
  - A hwmon companion driver to pwm-mc33xs2410 living in drivers/hwmon
    and acked by Guenter Roeck
 
  - chardev support for PWM devices
    This leverages atomic PWM updates to userspace and at the same time
    simplifies and accelerates PWM configuration changes.

bf977a9ad3 regulator: Updates for v6.17 
The big change in this release is the addition of Rust bindings from
 Daniel Almeida, allowing fairly basic consumer use with support for
 enable and voltage setting operations.  This should be good for the vast
 majority of consumers.  Otherwise it's been quite quiet, a few new
 devices supported, plus some cleanups and fixes.
 
  - Basic Rust bindings.
  - A fix for making large voltage changes on regulators where we limit
    the size of voltage change we will do in one step, previously we just
    got as close as we could in one step.
  - Cleanups of our usage of the PM autosuspend functions, this pulls in
    some PM core changes on a shared tag.
  - Mode setting support for PCA9450.
  - Support for Mediatek MT6893 and MT8196 DVFSRC, Qualcomm PM7550 and
    PMR735B, Raspberry Pi displays and TI TPS652G1.
 
 The TI driver pulls in the MFD portion of the support for the device and
 the pinctrl driver which was in the same tag.

fcb117e075 gpio updates for v6.17-rc1 
GPIOLIB core:
 - introduce a parallel, limited sysfs user ABI that doesn't expose the
   global GPIO numbers to user-space while maintaining backward
   compatibility with the end goal of it completely replacing the existing
   interface, allowing us to remove it
 - remove the legacy devm_gpio_request() routine which has no more users
 - start the process of allowing to compile-out the legacy parts of the
   GPIO core for users who don't need it by introducing a new Kconfig
   option: GPIOLIB_LEGACY
 - don't use global GPIO numbers in debugfs output from the core code
   (drivers still do it, the work is ongoing)
 - start the process of moving the fields specific to the gpio-mmio helper
   out of the core struct gpio_chip into their own structure that wraps
   it: create a new header with modern interfaces and convert several
   drivers to using it
 - remove the platform data structure associated with the gpio-mmio helper
   from the kernel after having converted all remaining users to generic
   device properties
 - remove legacy struct gpio definition as it has no more users
 
 New drivers:
 - add the GPIO driver for the Apple System Management Controller
 
 Driver improvements:
 - add support for new models to gpio-adp5585, gpio-tps65219 and
   gpio-pca953x
 - extend the interrupt support in gpio-loongson-64bit
 - allow to mark the simulated GPIO lines as invalid in gpio-sim
 - convert all remaining GPIO drivers to using the new GPIO value setter
   callbacks
 - convert gpio-rcar to using simple device power management ops callbacks
 - don't check if current direction of a line is output before setting
   the value in gpio-pisosr and ti-fpc202: the GPIO core already handles
   that
 - also drop unneeded GPIO range checks in drivers, the core already makes
   sure we're within bounds when calling driver callbacks
 - use dev_fwnode() where applicable across GPIO drivers
 - set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user
   wants to change direction of the pin to output even though these
   drivers don't need to do anything else to actually set the direction,
   otherwise a call like gpiod_direction_output(d, 1) will not result in
   the line driver high
 - remove the reduntant call to pm_runtime_mark_last_busy() from
   gpio-arizona
 - use lock guards in gpio-cadence and gpio-mxc
 - check the return values of regmap functions in gpio-wcd934x and
   gpio-tps65912
 - use better regmap interfaces in gpio-wcove and gpio-pca953x
 - remove dummy GPIO chip callbacks from several drivers in cases where
   the GPIO core can already handle their absence
 - allow building gpio-palmas as a module
 
 Fixes:
 - use correct bit widths (according to the documentation) in gpio-virtio
 
 Device-tree bindings:
 - convert several of the legacy .txt documents for many different devices
   to YAML, improving automatic validation
 - create a "trivial" GPIO DT schema that covers a wide range of simple
   hardware that share a set of basic GPIO properties
 - document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
 - document a new model for pca95xx
 - add and/or remove properties in YAML documents for gpio-rockchip,
   fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
 
 Misc:
 - some minor refactoring in several places, adding/removing forward
   declarations, moving defines to better places, constify the arguments
   in some functions, remove duplicate includes, etc.
 - documentation updates

Pull gpio updates from Bartosz Golaszewski:
 "There's one new driver (Apple SMC) and extensions to existing drivers
  for supporting new HW models. A lot of different impovements across
  drivers and in core GPIO code. Details on that are in the signed tag
  as usual.

  We managed to remove some of the legacy APIs. Arnd Bergmann started to
  work on making the legacy bits optional so that we may compile them
  only for older platforms that still really need them.

  Rob Herring has done a lot of work to convert legacy .txt dt-bindings
  for GPIO controllers to YAML. There are only a few left now in the
  GPIO tree.

  A big part of the commits in this PR concern the conversion of GPIO
  drivers to using the new line value setter callbacks. This conversion
  is now complete treewide (unless I've missed something) and once all
  the changes from different trees land in mainline, I'll send you
  another PR containing a commit dropping the legacy callbacks from the
  tree.

  As the quest to pay back technical dept never really ends, we're
  starting another set of interface conversions, this time it's about
  moving fields specific to only a handful of drivers using the
  gpio-mmio helper out of the core gpio_chip structure that every
  controller implements and uses. This cycle we introduce a new set of
  APIs and convert a few drivers under drivers/gpio/, next cycle we'll
  convert remaining modules treewide (in gpio, pinctrl and mfd trees)
  and finally remove the old interfaces and move the gpio-mmio fields
  into their own structure wrapping gpio_chip.

  One last change I should mention here is the rework of the sysfs
  interface. In 2016, we introduced the GPIO character device as the
  preferred alternative to the sysfs class under /sys/class/gpio. While
  it has seen a wide adoption with the help of its user-space
  counterpart - libgpiod - there are still users who prefer the
  simplicity of sysfs.

  As far as the GPIO subsystem is concerned, the problem is not the
  existince of the GPIO class as such but rather the fact that it
  exposes the global GPIO numbers to the user-space, stopping us from
  ever being able to remove the numberspace from the kernel. To that
  end, this release we introduced a parallel, limited sysfs interface
  that doesn't expose these numbers and only implements a subset of
  features that are relevant to the existing users. This is a result of
  several discussions over the course of last year and should allow us
  to remove the legacy part some time in the future.

  Summary:

  GPIOLIB core:
   - introduce a parallel, limited sysfs user ABI that doesn't expose
     the global GPIO numbers to user-space while maintaining backward
     compatibility with the end goal of it completely replacing the
     existing interface, allowing us to remove it
   - remove the legacy devm_gpio_request() routine which has no more
     users
   - start the process of allowing to compile-out the legacy parts of
     the GPIO core for users who don't need it by introducing a new
     Kconfig option: GPIOLIB_LEGACY
   - don't use global GPIO numbers in debugfs output from the core code
     (drivers still do it, the work is ongoing)
   - start the process of moving the fields specific to the gpio-mmio
     helper out of the core struct gpio_chip into their own structure
     that wraps it: create a new header with modern interfaces and
     convert several drivers to using it
   - remove the platform data structure associated with the gpio-mmio
     helper from the kernel after having converted all remaining users
     to generic device properties
   - remove legacy struct gpio definition as it has no more users

  New drivers:
   - add the GPIO driver for the Apple System Management Controller

  Driver improvements:
   - add support for new models to gpio-adp5585, gpio-tps65219 and
     gpio-pca953x
   - extend the interrupt support in gpio-loongson-64bit
   - allow to mark the simulated GPIO lines as invalid in gpio-sim
   - convert all remaining GPIO drivers to using the new GPIO value
     setter callbacks
   - convert gpio-rcar to using simple device power management ops
     callbacks
   - don't check if current direction of a line is output before setting
     the value in gpio-pisosr and ti-fpc202: the GPIO core already
     handles that
   - also drop unneeded GPIO range checks in drivers, the core already
     makes sure we're within bounds when calling driver callbacks
   - use dev_fwnode() where applicable across GPIO drivers
   - set line value in gpio-zynqmp-modepin and gpio-twl6040 when the
     user wants to change direction of the pin to output even though
     these drivers don't need to do anything else to actually set the
     direction, otherwise a call like gpiod_direction_output(d, 1) will
     not result in the line driver high
   - remove the reduntant call to pm_runtime_mark_last_busy() from
     gpio-arizona
   - use lock guards in gpio-cadence and gpio-mxc
   - check the return values of regmap functions in gpio-wcd934x and
     gpio-tps65912
   - use better regmap interfaces in gpio-wcove and gpio-pca953x
   - remove dummy GPIO chip callbacks from several drivers in cases
     where the GPIO core can already handle their absence
   - allow building gpio-palmas as a module

  Fixes:
   - use correct bit widths (according to the documentation) in
     gpio-virtio

  Device-tree bindings:
   - convert several of the legacy .txt documents for many different
     devices to YAML, improving automatic validation
   - create a "trivial" GPIO DT schema that covers a wide range of
     simple hardware that share a set of basic GPIO properties
   - document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
   - document a new model for pca95xx
   - add and/or remove properties in YAML documents for gpio-rockchip,
     fsl,qoriq-gpio, arm,pl061 and gpio-xilinx

  Misc:
   - some minor refactoring in several places, adding/removing forward
     declarations, moving defines to better places, constify the
     arguments in some functions, remove duplicate includes, etc.
   - documentation updates"

177bf8620c sound updates for 6.17-rc1 
This includes lots of file shuffling due to HD-audio code
 reorganization and many trivial changes, but otherwise there shouldn't
 be much surprise from the functionality POV.  The PR includes the PM
 changes as prerequisite, too.  Some highlights below:
 
 Core:
 - Performance optimizations in PCM core code
 - Refactoring of ASoC Kconfig menus to be hopefully more consistant
   and easier to navigate.
 - Refactoring of ASoC DAPM code, mainly hiding functionality that
   doesn't need to be exposed to drivers
 
 HD-audio reorganization:
 - All code are moved under sound/hda with a bit more understandable
   tree structure, as well as file renames
 - The huge Realtek driver code is split to several parts, a common
   helper module with driver modules per probe entry
 - HDMI and Cirrus codec drivers also split
 
 ASoC:
 - Further work on the generic handling for SoundWire SDCA devices
 - Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
   various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI
   TAS5753
 
 HD-audio and USB-audio:
 - TAS2781 driver cleanup and TAS2770 support
 - EQ enablement in CA0132 driver
 - USB audio quirk code cleanups
 
 Others:
 - Cleanups of PM autosuspend call patterns with the update from the PM
   tree
 - Lots of strcpy() -> strscpy() conversions for fixed size arrays

Pull power management updates from Rafael Wysocki:
 "As is tradition, cpufreq is the part with the largest number of
  updates that include core fixes and cleanups as well as updates of
  several assorted drivers, but there are also quite a few updates
  related to system sleep, mostly focused on asynchronous suspend and
  resume of devices and on making the integration of system suspend
  and resume with runtime PM easier.

  Runtime PM is also updated to allow some code duplication in drivers
  to be eliminated going forward and to work more consistently overall
  in some cases.

  Apart from that, there are some driver core updates related to PM
  domains that should help to address ordering issues with devm_ cleanup
  routines relying on PM domains, some assorted devfreq updates
  including core fixes and cleanups, tooling updates, and documentation
  and MAINTAINERS updates.

Pull selinux updates from Paul Moore:

 - Introduce the concept of a SELinux "neveraudit" type which prevents
   all auditing of the given type/domain.

   Taken by itself, the benefit of marking a SELinux domain with the
   "neveraudit" tag is likely not very interesting, especially given the
   significant overlap with the "dontaudit" tag.

   However, given that the "neveraudit" tag applies to *all* auditing of
   the tagged domain, we can do some fairly interesting optimizations
   when a SELinux domain is marked as both "permissive" and "dontaudit"
   (think of the unconfined_t domain).

   While this pull request includes optimized inode permission and
   getattr hooks, these optimizations require SELinux policy changes,
   therefore the improvements may not be visible on standard downstream
   Linux distos for a period of time.

 - Continue the deprecation process of /sys/fs/selinux/user.

   After removing the associated userspace code in 2020, we marked the
   /sys/fs/selinux/user interface as deprecated in Linux v6.13 with
   pr_warn() and the usual documention update.

   This adds a five second sleep after the pr_warn(), following a
   previous deprecation process pattern that has worked well for us in
   the past in helping identify any existing users that we haven't yet
   reached.

 - Add a __GFP_NOWARN flag to our initial hash table allocation.

   Fuzzers such a syzbot often attempt abnormally large SELinux policy
   loads, which the SELinux code gracefully handles by checking for
   allocation failures, but not before the allocator emits a warning
   which causes the automated fuzzing to flag this as an error and
   report it to the list. While we want to continue to support the work
   done by the fuzzing teams, we want to focus on proper issues and not
   an error case that is already handled safely. Add a NOWARN flag to
   quiet the allocator and prevent syzbot from tripping on this again.

 - Remove some unnecessary selinuxfs cleanup code, courtesy of Al.

 - Update the SELinux in-kernel documentation with pointers to
   additional information.
