14d0e1a09f soc: driver updates for 6.12 
Nothing particular important in the SoC driver updates, just the usual
 improvements to for drivers/soc and a couple of subsystems that don't
 fit anywhere else:
 
  - The largest set of updates is for Qualcomm SoC drivers, extending the
    set of supported features for additional SoCs in the QSEECOM, LLCC
    and socinfo drivers.a
 
  - The ti_sci firmware driver gains support for power managment
 
  - The drivers/reset subsystem sees a rework of the microchip
    sparx5 and amlogic reset drivers to support additional chips,
    plus a few minor updates on other platforms
 
  - The SCMI firmware interface driver gains support for two protocol
    extensions, allowing more flexible use of the shared memory area
    and new DT binding properties for configurability.
 
  - Mediatek SoC drivers gain support for power managment on the MT8188
    SoC and a new driver for DVFS.
 
  - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
    and a few bugfixes
 
  - The Hisilicon Kunpeng HCCS driver gains support for configuring
    lanes through sysfs
 
 Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
 and drivers/memory, including changing back the .remove_new callback
 to .remove, as well as a few other updates for freescale (powerpc)
 soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
 controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

79caa6c88a asm-generic updates for 6.13 
These are a number of unrelated cleanups, generally simplifying the
 architecture specific header files:
 
  - A series from Al Viro simplifies asm/vga.h, after it turns out that
    most of it can be generalized.
 
  - A series from Julian Vetter adds a common version of
    memcpy_{to,from}io() and memset_io() and changes most architectures
    to use that instead of their own implementation
 
  - A series from Niklas Schnelle concludes his work to make PC
    style inb()/outb() optional
 
  - Nicolas Pitre contributes improvements for the generic do_div()
    helper
 
  - Christoph Hellwig adds a generic version of page_to_phys()
    and phys_to_page(), replacing the slightly different architecture
    specific definitions.

bf9aa14fc5 A rather large update for timekeeping and timers: 
- The final step to get rid of auto-rearming posix-timers
 
     posix-timers are currently auto-rearmed by the kernel when the signal
     of the timer is ignored so that the timer signal can be delivered once
     the corresponding signal is unignored.
 
     This requires to throttle the timer to prevent a DoS by small intervals
     and keeps the system pointlessly out of low power states for no value.
     This is a long standing non-trivial problem due to the lock order of
     posix-timer lock and the sighand lock along with life time issues as
     the timer and the sigqueue have different life time rules.
 
     Cure this by:
 
      * Embedding the sigqueue into the timer struct to have the same life
        time rules. Aside of that this also avoids the lookup of the timer
        in the signal delivery and rearm path as it's just a always valid
        container_of() now.
 
      * Queuing ignored timer signals onto a seperate ignored list.
 
      * Moving queued timer signals onto the ignored list when the signal is
        switched to SIG_IGN before it could be delivered.
 
      * Walking the ignored list when SIG_IGN is lifted and requeue the
        signals to the actual signal lists. This allows the signal delivery
        code to rearm the timer.
 
     This also required to consolidate the signal delivery rules so they are
     consistent across all situations. With that all self test scenarios
     finally succeed.
 
   - Core infrastructure for VFS multigrain timestamping
 
     This is required to allow the kernel to use coarse grained time stamps
     by default and switch to fine grained time stamps when inode attributes
     are actively observed via getattr().
 
     These changes have been provided to the VFS tree as well, so that the
     VFS specific infrastructure could be built on top.
 
   - Cleanup and consolidation of the sleep() infrastructure
 
     * Move all sleep and timeout functions into one file
 
     * Rework udelay() and ndelay() into proper documented inline functions
       and replace the hardcoded magic numbers by proper defines.
 
     * Rework the fsleep() implementation to take the reality of the timer
       wheel granularity on different HZ values into account. Right now the
       boundaries are hard coded time ranges which fail to provide the
       requested accuracy on different HZ settings.
 
     * Update documentation for all sleep/timeout related functions and fix
       up stale documentation links all over the place
 
     * Fixup a few usage sites
 
   - Rework of timekeeping and adjtimex(2) to prepare for multiple PTP clocks
 
     A system can have multiple PTP clocks which are participating in
     seperate and independent PTP clock domains. So far the kernel only
     considers the PTP clock which is based on CLOCK TAI relevant as that's
     the clock which drives the timekeeping adjustments via the various user
     space daemons through adjtimex(2).
 
     The non TAI based clock domains are accessible via the file descriptor
     based posix clocks, but their usability is very limited. They can't be
     accessed fast as they always go all the way out to the hardware and
     they cannot be utilized in the kernel itself.
 
     As Time Sensitive Networking (TSN) gains traction it is required to
     provide fast user and kernel space access to these clocks.
 
     The approach taken is to utilize the timekeeping and adjtimex(2)
     infrastructure to provide this access in a similar way how the kernel
     provides access to clock MONOTONIC, REALTIME etc.
 
     Instead of creating a duplicated infrastructure this rework converts
     timekeeping and adjtimex(2) into generic functionality which operates
     on pointers to data structures instead of using static variables.
 
     This allows to provide time accessors and adjtimex(2) functionality for
     the independent PTP clocks in a subsequent step.
 
   - Consolidate hrtimer initialization
 
     hrtimers are set up by initializing the data structure and then
     seperately setting the callback function for historical reasons.
 
     That's an extra unnecessary step and makes Rust support less straight
     forward than it should be.
 
     Provide a new set of hrtimer_setup*() functions and convert the core
     code and a few usage sites of the less frequently used interfaces over.
 
     The bulk of the htimer_init() to hrtimer_setup() conversion is already
     prepared and scheduled for the next merge window.
 
   - Drivers:
 
     * Ensure that the global timekeeping clocksource is utilizing the
       cluster 0 timer on MIPS multi-cluster systems.
 
       Otherwise CPUs on different clusters use their cluster specific
       clocksource which is not guaranteed to be synchronized with other
       clusters.
 
     * Mostly boring cleanups, fixes, improvements and code movement

0352387523 First step of consolidating the VDSO data page handling: 
The VDSO data page handling is architecture specific for historical
   reasons, but there is no real technical reason to do so.
 
   Aside of that VDSO data has become a dump ground for various mechanisms
   and fail to provide a clear separation of the functionalities.
 
   Clean this up by:
 
     * consolidating the VDSO page data by getting rid of architecture
       specific warts especially in x86 and PowerPC.
 
     * removing the last includes of header files which are pulling in other
       headers outside of the VDSO namespace.
 
     * seperating timekeeping and other VDSO data accordingly.
 
   Further consolidation of the VDSO page handling is done in subsequent
   changes scheduled for the next merge window.
 
   This also lays the ground for expanding the VDSO time getters for
   independent PTP clocks in a generic way without making every architecture
   add support seperately.

Pull vdso data page handling updates from Thomas Gleixner:
 "First steps of consolidating the VDSO data page handling.

  The VDSO data page handling is architecture specific for historical
  reasons, but there is no real technical reason to do so.

  Aside of that VDSO data has become a dump ground for various
  mechanisms and fail to provide a clear separation of the
  functionalities.

  Clean this up by:

   - consolidating the VDSO page data by getting rid of architecture
     specific warts especially in x86 and PowerPC.

   - removing the last includes of header files which are pulling in
     other headers outside of the VDSO namespace.

   - seperating timekeeping and other VDSO data accordingly.

  Further consolidation of the VDSO page handling is done in subsequent
  changes scheduled for the next merge window.

  This also lays the ground for expanding the VDSO time getters for
  independent PTP clocks in a generic way without making every
  architecture add support seperately"

Merge tag 'vfs-6.13.file' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs file updates from Christian Brauner:
 "This contains changes the changes for files for this cycle:

   - Introduce a new reference counting mechanism for files.

     As atomic_inc_not_zero() is implemented with a try_cmpxchg() loop
     it has O(N^2) behaviour under contention with N concurrent
     operations and it is in a hot path in __fget_files_rcu().

     The rcuref infrastructures remedies this problem by using an
     unconditional increment relying on safe- and dead zones to make
     this work and requiring rcu protection for the data structure in
     question. This not just scales better it also introduces overflow
     protection.

     However, in contrast to generic rcuref, files require a memory
     barrier and thus cannot rely on *_relaxed() atomic operations and
     also require to be built on atomic_long_t as having massive amounts
     of reference isn't unheard of even if it is just an attack.

     This adds a file specific variant instead of making this a generic
     library.

     This has been tested by various people and it gives consistent
     improvement up to 3-5% on workloads with loads of threads.

   - Add a fastpath for find_next_zero_bit(). Skip 2-levels searching
     via find_next_zero_bit() when there is a free slot in the word that
     contains the next fd. This improves pts/blogbench-1.1.0 read by 8%
     and write by 4% on Intel ICX 160.

   - Conditionally clear full_fds_bits since it's very likely that a bit
     in full_fds_bits has been cleared during __clear_open_fds(). This
     improves pts/blogbench-1.1.0 read up to 13%, and write up to 5% on
     Intel ICX 160.

   - Get rid of all lookup_*_fdget_rcu() variants. They were used to
     lookup files without taking a reference count. That became invalid
     once files were switched to SLAB_TYPESAFE_BY_RCU and now we're
     always taking a reference count. Switch to an already existing
     helper and remove the legacy variants.

   - Remove pointless includes of <linux/fdtable.h>.

   - Avoid cmpxchg() in close_files() as nobody else has a reference to
     the files_struct at that point.

   - Move close_range() into fs/file.c and fold __close_range() into it.

   - Cleanup calling conventions of alloc_fdtable() and expand_files().

   - Merge __{set,clear}_close_on_exec() into one.

   - Make __set_open_fd() set cloexec as well instead of doing it in two
     separate steps"

* tag 'vfs-6.13.file' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  selftests: add file SLAB_TYPESAFE_BY_RCU recycling stressor
  fs: port files to file_ref

  fs: protect backing files with rcu

6d9f9115c0 drm/xe/guc: Fix dereference before NULL check 
The pointer list->list is dereferenced before the NULL check.
Fix this by moving the NULL check outside the for loop, so that
the check is performed before the dereferencing.
The list->list pointer cannot be NULL so this has no effect on runtime.
It's just a correctness issue.

be7eeaba2a drm/xe: handle flat ccs during hibernation on igpu 
Starting from LNL, CCS has moved over to flat CCS model where there is
now dedicated memory reserved for storing compression state. On
platforms like LNL this reserved memory lives inside graphics stolen
memory, which is not treated like normal RAM and is therefore skipped by
the core kernel when creating the hibernation image. Currently if
something was compressed and we enter hibernation all the corresponding
CCS state is lost on such HW, resulting in corrupted memory. To fix this
evict user buffers from TT -> SYSTEM to ensure we take a snapshot of the
raw CCS state when entering hibernation, where upon resuming we can
restore the raw CCS state back when next validating the buffer. This has
been confirmed to fix display corruption on LNL when coming back from
hibernation.

46f1f4b0f3 drm/xe: improve hibernation on igpu 
The GGTT looks to be stored inside stolen memory on igpu which is not
treated as normal RAM.  The core kernel skips this memory range when
creating the hibernation image, therefore when coming back from
hibernation the GGTT programming is lost. This seems to cause issues
with broken resume where GuC FW fails to load:

[drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1
[drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01
[drm] *ERROR* GT0: firmware signature verification failed
[drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged.

Current GGTT users are kernel internal and tracked as pinned, so it
should be possible to hook into the existing save/restore logic that we
use for dgpu, where the actual evict is skipped but on restore we
importantly restore the GGTT programming.  This has been confirmed to
fix hibernation on at least ADL and MTL, though likely all igpu
platforms are affected.

This also means we have a hole in our testing, where the existing s4
tests only really test the driver hooks, and don't go as far as actually
rebooting and restoring from the hibernation image and in turn powering
down RAM (and therefore losing the contents of stolen).

Panthor didn't correctly handle the case where the partial mapping
spanned multiple scatterlists and the mapping offset didn't point
to the 1st page of starting scatterlist. The offset variable was
not cleared after reaching the starting scatterlist.

Following warning messages were seen.

db0fc586ed drm/i915/gsc: ARL-H and ARL-U need a newer GSC FW. 
All MTL and ARL SKUs share the same GSC FW, but the newer platforms are
only supported in newer blobs. In particular, ARL-S is supported
starting from 102.0.10.1878 (which is already the minimum required
version for ARL in the code), while ARL-H and ARL-U are supported from
102.1.15.1926. Therefore, the driver needs to check which specific ARL
subplatform its running on when verifying that the GSC FW is new enough
for it.

6825cb07b7 drm/amd/display: Handle dml allocation failure to avoid crash 
[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.

[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer

In certain use case such as KDE login screen, there will be no atomic
commit while do the frame update.
If the Panel Replay enabled, it will cause the screen not updated and
looks like system hang.

[How]
Delay few atomic commits before enabled the Panel Replay just like PSR.
