Pull drm updates from Dave Airlie:
 "As part of building up nova-core/nova-drm pieces we've brought in some
  rust abstractions through this tree, aux bus being the main one, with
  devres changes also in the driver-core tree. Along with the drm core
  abstractions and enough nova-core/nova-drm to use them. This is still
  all stub work under construction, to build the nova driver upstream.

  The other big NVIDIA related one is nouveau adds support for
  Hopper/Blackwell GPUs, this required a new GSP firmware update to
  570.144, and a bunch of rework in order to support multiple fw
  interfaces.

  There is also the introduction of an asahi uapi header file as a
  precursor to getting the real driver in later, but to unblock
  userspace mesa packages while the driver is trapped behind rust
  enablement.

  Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
  and msm being the main ones, and some changes to vsprintf.

bfef148f36 drm/i915: Increase I915_PARAM_MMAP_GTT_VERSION version to indicate support for partial mmaps 
Commit 255fc1703e ("drm/i915/gem: Calculate object page offset for partial memory mapping")
was the last patch of several patches fixing multiple partial mmaps.
But without a bump in I915_PARAM_MMAP_GTT_VERSION there is no clean
way for UMD to know if it can do multiple partial mmaps.

d0efbe85e1 drm/i915: implement vmap/vunmap GEM object functions 
Implement i915_gem_vmap_object() and i915_gem_vunmap_object(),
based on i915_gem_dmabuf_vmap() and i915_gem_dmabuf_vunmap().

This enables a drm_client to use drm_client_buffer_vmap() and
drm_client_buffer_vunmap() on hardware using the i915 driver.

Tested with a currently out of tree pixelflut drm_client[1] on:
- Lenovo ThinkCentre M720q (CoffeeLake-S GT2 / Intel UHD Graphics 630)
- Dell Wyse N06D - 3030 LT (ValleyView on Intel Celeron N2807 SOC)

fe7fad476e drm/i915/pxp & drm/xe/pxp: Figure out pxp instance from the gem object 
It's undesirable to have to figure out the pxp pointer in display

Since we can figure the pxp pointer out in the pxp code from the gem
object, offload it there.

44a34dec43 drm/i915: Calculate the VT-d guard size in the display code 
Currently i915_gem_object_pin_to_display_plane() uses
i915_gem_object_get_tile_row_size() to calculate the tile row
size for the VT-d guard w/a. That's not really proper since
i915_gem_object_get_tile_row_size() only works for fenced BOs,
nor does it take rotation into account.

Remedy the situation by calculating the VT-d guard size in the
display code where we have more information readily available.
Although the default guard size (168 PTEs now) should cover
the more typical fb size use cases anyway, and only very large
Y/Yf-tiled framebuffers might have tile row size that exceeds it.

drm/i915: Fix page cleanup on DMA remap failure 
When converting to folios the cleanup path of shmem_get_pages() was
missed. When a DMA remap fails and the max segment size is greater than
PAGE_SIZE it will attempt to retry the remap with a PAGE_SIZEd segment
size. The cleanup code isn't properly using the folio apis and as a
result isn't handling compound pages correctly.

v2 -> v3:
(Ville) Just use shmem_sg_free_table() as-is in the failure path of
shmem_get_pages(). shmem_sg_free_table() will clear mapping unevictable
but it will be reset when it retries in shmem_sg_alloc_table().

1d6d399223 Kthreads affinity follow either of 4 existing different patterns: 
1) Per-CPU kthreads must stay affine to a single CPU and never execute
    relevant code on any other CPU. This is currently handled by smpboot
    code which takes care of CPU-hotplug operations. Affinity here is
    a correctness constraint.
 
 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't
    run anywhere else. The affinity is set through kthread_bind_mask()
    and the subsystem takes care by itself to handle CPU-hotplug
    operations. Affinity here is assumed to be a correctness constraint.
 
 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This
    is not a correctness constraint but merely a preference in terms of
    memory locality. kswapd and kcompactd both fall into this category.
    The affinity is set manually like for any other task and CPU-hotplug
    is supposed to be handled by the relevant subsystem so that the task
    is properly reaffined whenever a given CPU from the node comes up.
    Also care should be taken so that the node affinity doesn't cross
    isolated (nohz_full) cpumask boundaries.
 
 4) Similar to the previous point except kthreads have a _preferred_
    affinity different than a node. Both RCU boost kthreads and RCU
    exp kworkers fall into this category as they refer to "RCU nodes"
    from a distinctly distributed tree.
 
 Currently the preferred affinity patterns (3 and 4) have at least 4
 identified users, with more or less success when it comes to handle
 CPU-hotplug operations and CPU isolation. Each of which do it in its own
 ad-hoc way.
 
 This is an infrastructure proposal to handle this with the following API
 changes:
 
 _ kthread_create_on_node() automatically affines the created kthread to
   its target node unless it has been set as per-cpu or bound with
   kthread_bind[_mask]() before the first wake-up.
 
 - kthread_affine_preferred() is a new function that can be called right
   after kthread_create_on_node() to specify a preferred affinity
   different than the specified node.
 
 When the preferred affinity can't be applied because the possible
 targets are offline or isolated (nohz_full), the kthread is affine
 to the housekeeping CPUs (which means to all online CPUs most of the
 time or only the non-nohz_full CPUs when nohz_full= is set).
 
 kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been
 converted, along with a few old drivers.
 
 Summary of the changes:
 
 * Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu()
 
 * Introduce task_cpu_fallback_mask() that defines the default last
   resort affinity of a task to become nohz_full aware
 
 * Add some correctness check to ensure kthread_bind() is always called
   before the first kthread wake up.
 
 * Default affine kthread to its preferred node.
 
 * Convert kswapd / kcompactd and remove their halfway working ad-hoc
   affinity implementation
 
 * Implement kthreads preferred affinity
 
 * Unify kthread worker and kthread API's style
 
 * Convert RCU kthreads to the new API and remove the ad-hoc affinity
   implementation.

b04e317b52 treewide: Introduce kthread_run_worker[_on_cpu]() 
kthread_create() creates a kthread without running it yet. kthread_run()
creates a kthread and runs it.

On the other hand, kthread_create_worker() creates a kthread worker and
runs it.

This difference in behaviours is confusing. Also there is no way to
create a kthread worker and affine it using kthread_bind_mask() or
kthread_affine_preferred() before starting it.

Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]()
that behaves just like kthread_run(). kthread_create_worker[_on_cpu]()
will now only create a kthread worker without starting it.

bc6b027e6d drm/i915: Remove deadcode 
i915_active_acquire_for_context() was added in 2020 by
commit 5d9341370f ("drm/i915: Export a preallocate variant of
i915_active_acquire()") but has never been used.

The last use of __i915_gem_object_is_lmem() was removed in 2021 by
commit ff20afc4ce ("drm/i915: Update error capture code to avoid using
the current vma state")

Remove them.

Clean up the existing export namespace code along the same lines of

Now that we forcefully evict all DPT VMAs during suspend

fc5d96670e drm/ttm: Move swapped objects off the manager's LRU list 
Resources of swapped objects remains on the TTM_PL_SYSTEM manager's
LRU list, which is bad for the LRU walk efficiency.

Rename the device-wide "pinned" list to "unevictable" and move
also resources of swapped-out objects to that list.

An alternative would be to create an "UNEVICTABLE" priority to
be able to keep the pinned- and swapped objects on their
respective manager's LRU without affecting the LRU walk efficiency.

v2:
- Remove a bogus WARN_ON (Christian König)
- Update ttm_resource_[add|del] bulk move (Christian König)
- Fix TTM KUNIT tests (Intel CI)
v3:
- Check for non-NULL bo->resource in ttm_bo_populate().
v4:
- Don't move to LRU tail during swapout until the resource
  is properly swapped or there was a swapout failure.
  (Intel Ci)
- Add a newline after checkpatch check.
v5:
- Introduce ttm_resource_is_swapped() to avoid a corner-case where
  a newly created resource was considered swapped. (Intel CI)
v6:
- Move an assert.

8231ac7e72 drm/i915: use NULL for zero wakeref_t instead of plain integer 0 
As of commit 2edc6a75f2 ("drm/i915: switch intel_wakeref_t underlying
type to struct ref_tracker *") we gained quite a few sparse warnings
about "Using plain integer as NULL pointer" for using 0 to initialize
wakeref_t. Switch to NULL everywhere.

06f4d32843 drm/i915: remove IS_LP() 
The .is_lp member of struct intel_device_info and its wrapper IS_LP()
are used to identify just four platforms, VLV/CHV/BXT/GLK. It didn't
become as important as it was perhaps originally planned. Just remove
it, and replace with exact platform identification. In a few places this
becomes slightly verbose, but in many places it improves clarity to
immediately see the exact platforms.

Additionally, this lets us remove the xe compat macro.

394b524620 drm/i915/gem: fix bitwise and logical AND mixup 
CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND is an int, defaulting to 250. When
the wakeref is non-zero, it's either -1 or a dynamically allocated
pointer, depending on CONFIG_DRM_I915_DEBUG_RUNTIME_PM. It's likely that
the code works by coincidence with the bitwise AND, but with
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
condition evaluates to false, and intel_wakeref_auto() doesn't get
called. Switch to the intended logical AND.

9ea925c806 Updates for timers and timekeeping: 
- Core:
 
 	- Overhaul of posix-timers in preparation of removing the
 	  workaround for periodic timers which have signal delivery
 	  ignored.
 
         - Remove the historical extra jiffie in msleep()
 
 	  msleep() adds an extra jiffie to the timeout value to ensure
 	  minimal sleep time. The timer wheel ensures minimal sleep
 	  time since the large rewrite to a non-cascading wheel, but the
 	  extra jiffie in msleep() remained unnoticed. Remove it.
 
         - Make the timer slack handling correct for realtime tasks.
 
 	  The procfs interface is inconsistent and does neither reflect
 	  reality nor conforms to the man page. Show the correct 0 slack
 	  for real time tasks and enforce it at the core level instead of
 	  having inconsistent individual checks in various timer setup
 	  functions.
 
         - The usual set of updates and enhancements all over the place.
 
   - Drivers:
 
         - Allow the ACPI PM timer to be turned off during suspend
 
 	- No new drivers
