7c175aa1cc drm/msm/dpu: Only create debugfs for PRIMARY minor
dpu_kms_debugfs_init() is invoked for each minor being registered. Most
of the files created are unrelated to the minor, so there's no reason to
present them per minor.
The exception to this is the DisplayPort code, which ends up invoking
dp_debug_get() for each minor, each time associate the allocated object
with dp->debug.

As such dp_debug will create debugfs files in both the PRIMARY and the
RENDER minor's debugfs directory, but only the last reference will be
remembered.

The only use of this reference today is in the cleanup path in
dp_display_deinit_sub_modules() and the dp_debug_private object does
outlive the debugfs entries in either case, so there doesn't seem to be
any adverse effects of this, but per the code the current behavior is
unexpected, so change it to only create debugfs files for the PRIMARY
minor.

f3af2d6ee9 drm/msm/dpu: Add SC8180x to hw catalog
Add SC8180x to the hardware catalog, for initial support for the
platform. Due to limitations in the DP driver only one of the four DP
interfaces is left enabled.

The SC8180x platform supports the newly added DPU_INTF_WIDEBUS flag and
the Windows-on-Snapdragon bootloader leaves the widebus bit set, so this
is flagged appropriately to ensure widebus is disabled - for now.

740828c73a drm/msm/dpu: fix error handling in dpu_rm_init
Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover none of dpu_hw_*_init() functions can return NULL.
So, replace all dpu_rm_init()'s IS_ERR_OR_NULL() calls with IS_ERR().

ef58e0ad34 drm/msm/dpu: get INTF blocks directly rather than through RM
INTF blocks are not really handled by resource manager, they are
assigned at dpu_encoder_setup_display using dpu_encoder_get_intf().
Then this allocation is passed to RM and then returned to then
dpu_encoder.
So allocate them outside of RM and use them directly.

ddf4b773aa ocfs2: fix a deadlock when commit trans
commit 6f1b228529 introduces a regression which can deadlock as
follows:

  Task1:                              Task2:
  jbd2_journal_commit_transaction     ocfs2_test_bg_bit_allocatable
  spin_lock(&jh->b_state_lock)        jbd_lock_bh_journal_head
  __jbd2_journal_remove_checkpoint    spin_lock(&jh->b_state_lock)
  jbd2_journal_put_journal_head
  jbd_lock_bh_journal_head

Task1 and Task2 lock bh->b_state and jh->b_state_lock in different
order, which finally result in a deadlock.

So use jbd2_journal_[grab|put]_journal_head instead in
ocfs2_test_bg_bit_allocatable() to fix it.

27fe73394a mm, kasan: use compare-exchange operation to set KASAN page tag
It has been reported that the tag setting operation on newly-allocated
pages can cause the page flags to be corrupted when performed
concurrently with other flag updates as a result of the use of
non-atomic operations.

Fix the problem by using a compare-exchange loop to update the tag.

09c6304e38 kasan: test: fix compatibility with FORTIFY_SOURCE
With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform
dynamic checks using __builtin_object_size(ptr), which when failed will
panic the kernel.

Because the KASAN test deliberately performs out-of-bounds operations,
the kernel panics with FORTIFY_SOURCE, for example:

 | kernel BUG at lib/string_helpers.c:910!
 | invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI
 | CPU: 1 PID: 137 Comm: kunit_try_catch Tainted: G    B             5.16.0-rc3+ #3
 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014
 | RIP: 0010:fortify_panic+0x19/0x1b
 | ...
 | Call Trace:
 |  kmalloc_oob_in_memset.cold+0x16/0x16
 |  ...

Fix it by also hiding `ptr` from the optimizer, which will ensure that
__builtin_object_size() does not return a valid size, preventing
fortified string functions from panicking.

61e28cf054 memory-failure: fetch compound_head after pgmap_pfn_valid()
memory_failure_dev_pagemap() at the moment assumes base pages (e.g.
dax_lock_page()).  For devmap with compound pages fetch the
compound_head in case a tail page memory failure is being handled.

Currently this is a nop, but in the advent of compound pages in
dev_pagemap it allows memory_failure_dev_pagemap() to keep working.

Without this fix memory-failure handling (i.e.  MCEs on pmem) with
device-dax configured namespaces will regress (and crash).

e7f1e8834b binfmt_misc: fix crash when load/unload module
We should unregister the table upon module unload otherwise something
horrible will happen when we load binfmt_misc module again.  Also note
that we should keep value returned by register_sysctl_mount_point() and
release it later, otherwise it will leak.

Also, per Christian's comment, to fully restore the old behavior that
won't break userspace the check(binfmt_misc_header) should be
eliminated.

To reproduce:
  modprobe binfmt_misc
  modprobe -r binfmt_misc
  modprobe binfmt_misc
  modprobe -r binfmt_misc
  modprobe binfmt_misc

resulting in

  modprobe: can't load module binfmt_misc (kernel/fs/binfmt_misc.ko): Cannot allocate memory

and an unhappy kernel:

  binfmt_misc: Failed to create fs/binfmt_misc sysctl mount point

Pull arm64 fixes from Catalin Marinas:

 - Errata workarounds for Cortex-A510: broken hardware dirty bit
   management, detection code for the TRBE (tracing) bugs with the
   actual fixes going in via the CoreSight tree.

 - Cortex-X2 errata handling for TRBE (inheriting the workarounds from
   Cortex-A710).

 - Fix ex_handler_load_unaligned_zeropad() to use the correct struct
   members.

 - A couple of kselftest fixes for FPSIMD.

 - Silence the vdso "no previous prototype" warning.

 - Mark start_backtrace() notrace and NOKPROBE_SYMBOL.
