After the commit in the Fixes: line below, HPD polling stopped working
on i915, since after that change calling drm_kms_helper_poll_enable()
doesn't restart drm_mode_config::output_poll_work if the work was
stopped (no connectors needing polling) and enabling polling for a
connector (during runtime suspend or detecting an HPD IRQ storm).

After the above change calling drm_kms_helper_poll_enable() is a nop
after it's been called already and polling for some connectors was
disabled/re-enabled.

Fix this by calling drm_kms_helper_poll_reschedule() added in the
previous patch instead, which reschedules the work whenever expected.

Add a helper to reschedule drm_mode_config::output_poll_work after
polling has been enabled for a connector (and needing a reschedule,
since previously polling was disabled for all connectors and hence
output_poll_work was not running).

This is needed by the next patch fixing HPD polling on i915.

vmw_bo_unreference sets the input buffer to null on exit, resulting in
null ptr deref's on the subsequent drm gem put calls.

This went unnoticed because only very old userspace would be exercising
those paths but it wouldn't be hard to hit on old distros with brand
new kernels.

Introduce a new function that abstracts unrefing of user bo's to make
the code cleaner and more explicit.

If a signal callback releases the sw_sync fence, that will trigger a
deadlock as the timeline_fence_release recurses onto the fence->lock
(used both for signaling and the the timeline tree).

To avoid that, temporarily hold an extra reference to the signalled
fences until after we drop the lock.

(This is an alternative implementation of https://patchwork.kernel.org/patch/11664717/
which avoids some potential UAF issues with the original patch.)

  blk-mq: release scheduler resource when request completes
  blk-crypto: dynamically allocate fallback profile
  blk-cgroup: hold queue_lock when removing blkg->q_node
  drivers/rnbd: restore sysfs interface to rnbd-client

Chuck reported [1] an IO hang problem on NFS exports that reside on SATA
devices and bisected to commit 615939a2 ("blk-mq: defer to the normal
submission path for post-flush requests").

We analysed the IO hang problem, found there are two postflush requests
waiting for each other.

The first postflush request completed the REQ_FSEQ_DATA sequence, so go to
the REQ_FSEQ_POSTFLUSH sequence and added in the flush pending list, but
failed to blk_kick_flush() because of the second postflush request which
is inflight waiting in scheduler queue.

The second postflush waiting in scheduler queue can't be dispatched because
the first postflush hasn't released scheduler resource even though it has
completed by itself.

Fix it by releasing scheduler resource when the first postflush request
completed, so the second postflush can be dispatched and completed, then
make blk_kick_flush() succeed.

While at it, remove the check for e->ops.finish_request, as all
schedulers set that. Reaffirm this requirement by adding a WARN_ON_ONCE()
at scheduler registration time, just like we do for insert_requests and
dispatch_request.

 "Extraordinary embargoed times call for extraordinary measures. That's

  the known fallout fixes after the SRSO mitigation got merged.

  I know, it is a bit late in the game but everyone who has reported a
  bug stemming from the SRSO pile, has tested that branch and has
  confirmed that it fixes their bug.

  Also, I've run it on every possible hardware I have and it is looking
  good. It is running on this very machine while I'm typing, for 2 days
  now without an issue. Famous last words...

   - Use LEA ...%rsp instead of ADD %rsp in the Zen1/2 SRSO return
     sequence as latter clobbers flags which interferes with fastop
     emulation in KVM, leading to guests freezing during boot

   - A fix for the DIV(0) quotient data leak on Zen1 to clear the
     divider buffers at the right time

   - Disable the SRSO mitigation on unaffected configurations as it got
     enabled there unnecessarily

   - Change .text section name to fix CONFIG_LTO_CLANG builds

   - Improve the optprobe indirect jmp check so that certain
     configurations can still be able to use optprobes at all

   - A serious and good scrubbing of the untraining routines by PeterZ:
      - Add proper speculation stopping traps so that objtool is happy
      - Adjust objtool to handle the new thunks
      - Make the thunk pointer assignable to the different untraining
        sequences at runtime, thus avoiding the alternative at the
        return thunk. It simplifies the code a bit too.
      - Add a entry_untrain_ret() main entry point which selects the
        respective untraining sequence
      - Rename things so that they're more clear
      - Fix stack validation with FRAME_POINTER=y builds

   - Fix static call patching to handle when a JMP to the return thunk
     is the last insn on the very last module memory page

   - Add more documentation about what each untraining routine does and

Pull ARM SoC fixes from Arnd Bergmann:
 "As usual, mostly DT fixes for the major Arm platforms from Qualcomm

  The qualcomm fixes mainly deal with their higher-end arm64 devices

  regression for the DSI phy.

  NXP i.MX has two correctness fixes for the 64-bit chips, dealing with
  the imx93 "anatop" module and the CSI interface. On the 32-bit side,
  there are functional fixes for RTC, display and SD card intefaces.

  Rockchip fixes are for wifi support on certain boards, a eMMC
  stability and DT build warnings.

  On TI OMAP, a regulator is described in DT to avoid problems with the
  ethernet phy initialization.

  The code changes include a missing MMIO serialization on OMAP, plus a
  few minor fixes on ASpeed and AMD/Zynq chips"

In production we were seeing a variety of WARN_ON()'s in the extent_map
code, specifically in btrfs_drop_extent_map_range() when we have to call
add_extent_mapping() for our second split.

Consider the following extent map layout

	PINNED
	[0 16K)  [32K, 48K)

and then we call btrfs_drop_extent_map_range for [0, 36K), with
skip_pinned == true.  The initial loop will have

	start = 0
	end = 36K
	len = 36K

we will find the [0, 16k) extent, but since we are pinned we will skip
it, which has this code

	start = em_end;
	if (end != (u64)-1)
		len = start + len - em_end;

em_end here is 16K, so now the values are

	start = 16K
	len = 16K + 36K - 16K = 36K

len should instead be 20K.  This is a problem when we find the next
extent at [32K, 48K), we need to split this extent to leave [36K, 48k),
however the code for the split looks like this

	split->start = start + len;
	split->len = em_end - (start + len);

In this case we have

	em_end = 48K
	split->start = 16K + 36K       // this should be 16K + 20K
	split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K

and now we have an invalid extent_map in the tree that potentially
overlaps other entries in the extent map.  Even in the non-overlapping
case we will have split->start set improperly, which will cause problems
with any block related calculations.

We don't actually need len in this loop, we can simply use end as our
end point, and only adjust start up when we find a pinned extent we need
to skip.

Adjust the logic to do this, which keeps us from inserting an invalid
extent map.

We only skip_pinned in the relocation case, so this is relatively rare,
except in the case where you are running relocation a lot, which can
happen with auto relocation on.

In case the downstream bridge or panel uses DSI transfers before the
DSI host was actually initialized through samsung_dsim_atomic_enable()
which clears the stop state (LP11) mode, all transfers will fail.

This happens with downstream bridges that are controlled by DSI
commands such as the tc358762.

As documented in [1] DSI hosts are expected to allow transfers
outside the normal bridge enable/disable flow.

To fix this make sure that stop state is cleared in
samsung_dsim_host_transfer() which restores the previous
behavior.

We also factor out the common code to enable/disable stop state
to samsung_dsim_set_stop_state().
