df14b7f9ef sched/core: Fix a missed update of user_cpus_ptr
Since commit 8f9ea86fdf ("sched: Always preserve the user requested
cpumask"), a successful call to sched_setaffinity() should always save
the user requested cpu affinity mask in a task's user_cpus_ptr. However,
when the given cpu mask is the same as the current one, user_cpus_ptr
is not updated. Fix this by saving the user mask in this case too.

eedeb787eb freezer,umh: Fix call_usermode_helper_exec() vs SIGKILL
Tetsuo-San noted that commit f5d39b0208 ("freezer,sched: Rewrite
core freezer logic") broke call_usermodehelper_exec() for the KILLABLE
case.

Specifically it was missed that the second, unconditional,
wait_for_completion() was not optional and ensures the on-stack
completion is unused before going out-of-scope.

5e98e916f9 tracing: Fix showing of TASK_COMM_LEN instead of its value
The TASK_COMM_LEN was converted from a macro into an enum so that BTF
 would have access to it. But this unfortunately caused TASK_COMM_LEN to
 display in the format fields of trace events, as they are created by the
 TRACE_EVENT() macro and such, macros convert to their values, where as
 enums do not.
 
 To handle this, instead of using the field itself to be display, save the
 value of the array size as another field in the trace_event_fields
 structure, and use that instead. Not only does this fix the issue, but
 also converts the other trace events that have this same problem (but were
 not breaking tooling). With this change, the original work around
 b3bc8547d3 ("tracing: Have TRACE_DEFINE_ENUM affect trace event types
 as well") could be reverted (but that should be done in the merge window).

462a8e08e0 Fix page corruption caused by racy check in __free_pages
When we upgraded our kernel, we started seeing some page corruption like
the following consistently:

  BUG: Bad page state in process ganesha.nfsd  pfn:1304ca
  page:0000000022261c55 refcount:0 mapcount:-128 mapping:0000000000000000 index:0x0 pfn:0x1304ca

  Call Trace:

   alloc_pages_current+0x87/0xf0
   skb_page_frag_refill+0x84/0x110
   ...

Sometimes, it would also show up as corruption in the free list pointer
and cause crashes.

After bisecting the issue, we found the issue started from commit
e320d3012d ("mm/page_alloc.c: fix freeing non-compound pages"):

	if (put_page_testzero(page))
		free_the_page(page, order);
	else if (!PageHead(page))
		while (order-- > 0)
			free_the_page(page + (1 << order), order);

So the problem is the check PageHead is racy because at this point we
already dropped our reference to the page.  So even if we came in with
compound page, the page can already be freed and PageHead can return
false and we will end up freeing all the tail pages causing double free.

b6c7abd1c2 tracing: Fix TASK_COMM_LEN in trace event format file
After commit 3087c61ed2 ("tools/testing/selftests/bpf: replace open-coded 16 with TASK_COMM_LEN"),
the content of the format file under
/sys/kernel/tracing/events/task/task_newtask was changed from
  field:char comm[16];    offset:12;    size:16;    signed:0;
to
  field:char comm[TASK_COMM_LEN];    offset:12;    size:16;    signed:0;

John reported that this change breaks older versions of perfetto.
Then Mathieu pointed out that this behavioral change was caused by the
use of __stringify(_len), which happens to work on macros, but not on enum
labels. And he also gave the suggestion on how to fix it:
  :One possible solution to make this more robust would be to extend
  :struct trace_event_fields with one more field that indicates the length
  :of an array as an actual integer, without storing it in its stringified
  :form in the type, and do the formatting in f_show where it belongs.

The result as follows after this change,
$ cat /sys/kernel/tracing/events/task/task_newtask/format
        field:char comm[16];    offset:12;      size:16;        signed:0;

 The pages being freed by memblock_free_late() have already been

 might access nearby uninitialized pages when trying to coalesce buddies,
 which will cause a crash.

ff209ecc37 Revert "PCI/ASPM: Refactor L1 PM Substates Control Register programming"
This reverts commit 5e85eba6f5.

Thomas Witt reported that 5e85eba6f5 ("PCI/ASPM: Refactor L1 PM Substates
Control Register programming") broke suspend/resume on a Tuxedo
Infinitybook S 14 v5, which seems to use a Clevo L140CU Mainboard.

The main symptom is:

  iwlwifi 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible
  nvme 0000:03:00.0: Unable to change power state from D3hot to D0, device inaccessible

and the machine is only partially usable after resume.  It can't run dmesg
and can't do a clean reboot.  This happens on every suspend/resume cycle.

Revert 5e85eba6f5 until we can figure out the root cause.

a7152be79b Revert "PCI/ASPM: Save L1 PM Substates Capability for suspend/resume"
This reverts commit 4ff116d0d5.

Tasev Nikola and Mark Enriquez reported that resume from suspend was broken
in v6.1-rc1.  Tasev bisected to a47126ec29 ("PCI/PTM: Cache PTM
Capability offset"), but we can't figure out how that could be related.

Mark saw the same symptoms and bisected to 4ff116d0d5 ("PCI/ASPM: Save L1
PM Substates Capability for suspend/resume"), which does have a connection:
it restores L1 Substates configuration while ASPM L1 may be enabled:

  pci_restore_state
    pci_restore_aspm_l1ss_state
      aspm_program_l1ss
        pci_write_config_dword(PCI_L1SS_CTL1, ctl1)         # L1SS restore
    pci_restore_pcie_state
      pcie_capability_write_word(PCI_EXP_LNKCTL, cap[i++])  # L1 restore

which is a problem because PCIe r6.0, sec 5.5.4, requires that:

  If setting either or both of the enable bits for ASPM L1 PM
  Substates, both ports must be configured as described in this
  section while ASPM L1 is disabled.

Separately, Thomas Witt reported that 5e85eba6f5 ("PCI/ASPM: Refactor L1
PM Substates Control Register programming") broke suspend/resume, and it
depends on 4ff116d0d5.

Revert 4ff116d0d5 ("PCI/ASPM: Save L1 PM Substates Capability for
suspend/resume") to fix the resume issue and enable revert of 5e85eba6f5
to fix the issue Thomas reported.

Note that reverting 4ff116d0d5 means L1 Substates config may be lost on
suspend/resume.  As far as we know the system will use more power but will
still *work* correctly.

4f72a263e1 ARM: SoC fixes for 6.2, part 4
All the changes this time are minor devicetree corrections, the majority
 being for 64-bit Rockchip SoC support. These are a couple of corrections
 for properties that are in violation of the binding, some that put the
 machine into safer operating points for the eMMC and thermal settings,
 and missing properties that prevented rk356x PCIe and ethernet from
 working correctly.
 
 The changes for amlogic and mediatek address incorrect properties that
 were preventing the display support on MT8195 and the MMC support
 on various Meson SoCs from working correctly.
 
 The stihxxx-b2120 change fixes the GPIO polarity for the DVB tuner
 to allow this to be used correctly after a futre driver change,
 though it has no effect on older kernels.

Merge tag 'riscv-for-linus-6.2-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:
 "This is a little bigger that I'd hope for this late in the cycle, but
  they're all pretty concrete fixes and the only one that's bigger than
  a few lines is pmdp_collapse_flush() (which is almost all
  boilerplate/comment). It's also all bug fixes for issues that have
  been around for a while.

  So I think it's not all that scary, just bad timing.

   - avoid partial TLB fences for huge pages, which are disallowed by
     the ISA

   - avoid missing a frame when dumping stacks

   - avoid misaligned accesses (and possibly overflows) in kprobes

   - fix a race condition in tracking page dirtiness"

 "Weekly fixes.

  The amdgpu had a few small fixes to display flicker on certain
  configurations, however it was found the the flicker was lessened but
  there were other unintended consequences, so for now they've been
  reverted and replaced with an option for users to test with so future
  fixes can be developed.

riscv: Fixup race condition on PG_dcache_clean in flush_icache_pte
In commit 588a513d34 ("arm64: Fix race condition on PG_dcache_clean
in __sync_icache_dcache()"), we found RISC-V has the same issue as the
previous arm64. The previous implementation didn't guarantee the correct
sequence of operations, which means flush_icache_all() hasn't been
called when the PG_dcache_clean was set. That would cause a risk of page
synchronization.

5f58d783fd btrfs: free device in btrfs_close_devices for a single device filesystem
We have this check to make sure we don't accidentally add older devices
that may have disappeared and re-appeared with an older generation from
being added to an fs_devices (such as a replace source device). This
makes sense, we don't want stale disks in our file system. However for
single disks this doesn't really make sense.

I've seen this in testing, but I was provided a reproducer from a
project that builds btrfs images on loopback devices. The loopback
device gets cached with the new generation, and then if it is re-used to
generate a new file system we'll fail to mount it because the new fs is
"older" than what we have in cache.

Fix this by freeing the cache when closing the device for a single device
filesystem. This will ensure that the mount command passed device path is
scanned successfully during the next mount.

519b7e13b5 btrfs: lock the inode in shared mode before starting fiemap
Currently fiemap does not take the inode's lock (VFS lock), it only locks
a file range in the inode's io tree. This however can lead to a deadlock
if we have a concurrent fsync on the file and fiemap code triggers a fault
when accessing the user space buffer with fiemap_fill_next_extent(). The
deadlock happens on the inode's i_mmap_lock semaphore, which is taken both
by fsync and btrfs_page_mkwrite(). This deadlock was recently reported by
syzbot and triggers a trace like the following:

What happens is the following:

1) Task A is doing an fsync, enters btrfs_sync_file() and flushes delalloc
   before locking the inode and the i_mmap_lock semaphore, that is, before
   calling btrfs_inode_lock();

2) After task A flushes delalloc and before it calls btrfs_inode_lock(),
   another task dirties a page;

3) Task B starts a fiemap without FIEMAP_FLAG_SYNC, so the page dirtied
   at step 2 remains dirty and unflushed. Then when it enters
   extent_fiemap() and it locks a file range that includes the range of
   the page dirtied in step 2;

4) Task A calls btrfs_inode_lock() and locks the inode (VFS lock) and the
   inode's i_mmap_lock semaphore in write mode. Then it tries to flush
   delalloc by calling start_ordered_ops(), which will block, at
   find_lock_delalloc_range(), when trying to lock the range of the page
   dirtied at step 2, since this range was locked by the fiemap task (at
   step 3);

5) Task B generates a page fault when accessing the user space fiemap
   buffer with a call to fiemap_fill_next_extent().

   The fault handler needs to call btrfs_page_mkwrite() for some other
   page of our inode, and there we deadlock when trying to lock the
   inode's i_mmap_lock semaphore in read mode, since the fsync task locked
   it in write mode (step 4) and the fsync task can not progress because
   it's waiting to lock a file range that is currently locked by us (the
   fiemap task, step 3).

Fix this by taking the inode's lock (VFS lock) in shared mode when
entering fiemap. This effectively serializes fiemap with fsync (except the
most expensive part of fsync, the log sync), preventing this deadlock.

e7d636476b Revert "drm/amd/display: disable S/G display on DCN 3.1.5"
This reverts commit 3cc67fe1b3.

Some users have reported flickerng with S/G display.  We've
tried extensively to reproduce and debug the issue on a wide
variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to.  We
disabled S/G display on a number of platforms to address this
but that leads to failure to pin framebuffers errors and
blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).
We have a parameter to disable this as a debugging option as a
way for users to disable this, depending on their use case,
and for us to help debug this further.  Having this enabled
seems like the lesser of to evils.
