288fc86067 gfs2 debugfs improvements
- Improve the way how the state of glocks is reported in debugfs
   for glocks which are not held by processes, but rather by other
   resouces like cached inodes or flocks.

4875d2ffb0 gfs2 fixes
- Make sure to initialize the filesystem work queues before registering
   the filesystem; this prevents them from being used uninitialized.
 
 - On filesystem withdraw: prevent a a double iput() and immediately
   reject pending locking requests that can no longer succeed.
 
 - Use TRY lock in gfs2_inode_lookup() to prevent a rare glock hang
   during evict.
 
 - During filesystem mount, explicitly make sure that the sb_bsize and
   sb_bsize_shift super block fields are consistent with each other.
   This prevents messy error messages during fuzz testing.
 
 - Switch from strlcpy to strscpy.

27bc50fc90 - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any negative
   reports (or any positive ones, come to that).
 
 - Also the Maple Tree from Liam R.  Howlett.  An overlapping range-based
   tree for vmas.  It it apparently slight more efficient in its own right,
   but is mainly targeted at enabling work to reduce mmap_lock contention.
 
   Liam has identified a number of other tree users in the kernel which
   could be beneficially onverted to mapletrees.
 
   Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
   (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com).
   This has yet to be addressed due to Liam's unfortunately timed
   vacation.  He is now back and we'll get this fixed up.
 
 - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer.  It uses
   clang-generated instrumentation to detect used-unintialized bugs down to
   the single bit level.
 
   KMSAN keeps finding bugs.  New ones, as well as the legacy ones.
 
 - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
   memory into THPs.
 
 - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support
   file/shmem-backed pages.
 
 - userfaultfd updates from Axel Rasmussen
 
 - zsmalloc cleanups from Alexey Romanov
 
 - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure
 
 - Huang Ying adds enhancements to NUMA balancing memory tiering mode's

Pull x86 mm updates from Dave Hansen:
 "There are some small things here, plus one big one.

  The big one detected and refused to create W+X kernel mappings. This
  caused a bit of trouble and it is entirely disabled on 32-bit due to
  known unfixable EFI issues. It also oopsed on some systemd eBPF use,
  which kept some users from booting.

  The eBPF issue is fixed, but those troubles were caught relatively
  recently which made me nervous that there are more lurking. The final
  commit in here retains the warnings, but doesn't actually refuse to
  create W+X mappings.

  Summary:

   - Detect insecure W+X mappings and warn about them, including a few
     bug fixes and relaxing the enforcement

   - Do a long-overdue defconfig update and enabling W+X boot-time
     detection

   - Cleanup _PAGE_PSE handling (follow-up on an earlier bug)

   - Rename a change_page_attr function"

faf4d8e07f drm/amd/display: fix array-bounds error in dc_stream_remove_writeback() [take 2]
Commit 5d8c3e836f ("drm/amd/display: fix array-bounds error in
dc_stream_remove_writeback()") tried to fix an array bounds error seen
with gcc 12.0. Unfortunately, that results in another array bounds error,
seen with older versions of gcc.

We could check both i and j for overflow to fix the problem. That would,
however, be not make much sense since it is known and provable that j <= i.
Also, the check introduced with commit 5d8c3e836f does not really add
value since it checks if j < MAX_DWB_PIPES. Since it is known that j <= i,
it would make more sense to check if i < MAX_DWB_PIPES. Unfortunately, that
does not help to solve the problem observed here: gcc still complains.

To solve the problem, replace the subsequent check for 'i != j' with
'j < i'. This is identical to the original check since we know that j <= i,
and it makes all versions of gcc happy. Drop the check introduced with
commit 5d8c3e836f since it is not really useful and does not solve the
problem.

e5da651985 drm/amdgpu: Fix SDMA engine resume issue under SRIOV
- Under SRIOV, SDMA engine is shared between VFs. Therefore,
  we will not stop SDMA during hw_fini. This is not an issue
  with normal dirver loading and unloading.

- However, when we put the SDMA engine to suspend state and resume
  it, the issue starts to show up. Something could attempt to use
  that SDMA engine to clear or move memory before the engine is
  initialized since the DRM entity is still there.

- Therefore, we will call sdma_v5_2_enable(false) during hw_fini,
  and if we are under SRIOV, we will call sdma_v5_2_enable(true)
  afterwards to allow other VFs to use SDMA. This way, the DRM
  entity of SDMA engine is emptied and it will follow the flow
  of resume code path.

6f4f8ff567 drm/amd/display: Display does not light up after S4 resume
[Why]
Dpia hpd interrupt processing is disabled when entering S4/S0i3 and
would be reenabled after detection completes during resuming. Because,
keeping hpd interrupts enabled during detection leads to multiple
detections for the same hpd transition. There is a S4 case where dpia
hpd interrupt is missed when driver is in transitioning from hpd
interrupt processing disable to enable and the display does not light
up.

[How]
- Added dmub inbox command DMUB_CMD__DPIA_HPD_INT_ENABLE to explicitly
control dmub to issue dpia hpd interrupt or not. If dpia hpd interrupt
is disabled, dmub will keep the hpd pending and post it once driver
reenables dpia hpd interrupt or when querying with
DMUB_CMD__QUERY_HPD_STATE.
- Added dmub boot option dpia_hpd_int_enable_supported to notify dmub
about whether DMUB_CMD__DPIA_HPD_INT_ENABLE command would be used.

876fcc4222 drm/amd/display: Validate DSC After Enable All New CRTCs
Before enabling new crtc, stream_count in dc_state does not sync with
that in drm_atomic_state. Validating dsc in such case would leave newly
added stream not jointly participating in dsc optimization with existing
streams, but simply using default initialized vcpi all the time which
gives wrong dsc determination decision.

Consider the scenaio where one 4k60 connected to the dock under dp-alt mode.
Since dp-alt mode is 2-lane setup, stream 1 consumes 63 slots with dsc needed.
Then hook up a second 4k60 to the dock.
stream 2 connected with 65 slot initialized by default without dsc.  dsc
pre validate will not jointly optimize stream 2 with stream 1 before
crtc 2 added into the dc_state. That leads to stream 2 not getting dsc
optimization, and trigger atomic_check failure all the time, as 65 > 63
limit.

After getting all new crtcs added into the state, stream_count in
dc_state correctly reflect that in drm_atomic_state which comes up with
correct dsc decision.

eae2331899 drm/amd/display: properly configure DCFCLK when enable/disable Freesync
[Why]
Bandwidth validation is using Freesync parameters
from previous Freesync state.
Bandwidth validation ignores DCFCLK calculated
after Freesync parameters are configured

[How]
Set Freesync bandwidth parameters to its default
state before running bandwidth validation.
Take DCFCLK calculated after Freesync bandwidth
parameters are assigned and bandwidth is
recalculated.

03db771615 Revert "cgroup: enable cgroup_get_from_file() on cgroup1"
This reverts commit f3a2aebdd6.

The commit enabled looking up v1 cgroups via cgroup_get_from_file().
However, there are multiple users, including CLONE_INTO_CGROUP, which have
been assuming that it would only look up v2 cgroups. Returning v1 cgroups
breaks them.

Let's revert the commit and retry later with a separate lookup interface
which allows both v1 and v2.

46307fd6e2 cgroup: Reorganize css_set_lock and kernfs path processing
The commit 74e4b956eb incorrectly wrapped kernfs_walk_and_get
(might_sleep) under css_set_lock (spinlock). css_set_lock is needed by
__cset_cgroup_from_root to ensure stable cset->cgrp_links but not for
kernfs_walk_and_get.

We only need to make sure that the returned root_cgrp won't be freed
under us. This is given in the case of global root because it is static
(cgrp_dfl_root.cgrp). When the root_cgrp is lower in the hierarchy, it
is pinned by cgroup_ns->root_cset (and `current` task cannot switch
namespace asynchronously so ns_proxy pins cgroup_ns).

Note this reasoning won't hold for root cgroups in v1 hierarchies,

f23cdfcd04 IOMMU Updates for Linux v6.1:
Including:
 
 	- Removal of the bus_set_iommu() interface which became
 	  unnecesary because of IOMMU per-device probing
 
 	- Make the dma-iommu.h header private
 
 	- Intel VT-d changes from Lu Baolu:
 	  - Decouple PASID and PRI from SVA
 	  - Add ESRTPS & ESIRTPS capability check
 	  - Cleanups
 
 	- Apple DART support for the M1 Pro/MAX SOCs
 
 	- Support for AMD IOMMUv2 page-tables for the DMA-API layer. The
 	  v2 page-tables are compatible with the x86 CPU page-tables.
 	  Using them for DMA-API prepares support for hardware-assisted
 	  IOMMU virtualization
 
 	- Support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver
 
 	- Some smaller fixes and cleanups
