ASoC: Quirk for v6.5

One additional fix for v6.5, an additional quirk.  As with the other
fixes this could wait for the merge window.

Pull tracing fixes from Steven Rostedt:

 - Fix ring buffer being permanently disabled due to missed
   record_disabled()

   Changing the trace cpu mask will disable the ring buffers for the
   CPUs no longer in the mask. But it fails to update the snapshot
   buffer. If a snapshot takes place, the accounting for the ring buffer
   being disabled is corrupted and this can lead to the ring buffer
   being permanently disabled.

 - Add test case for snapshot and cpu mask working together

 - Fix memleak by the function graph tracer not getting closed properly.

   The iterator is used to read the ring buffer. When it opens, it calls
   the open function of a tracer, and when it is closed, it calls the
   close iteration. While a trace is being read, it is still possible to
   change the tracer.

   If this happens between the function graph tracer and the wakeup
   tracer (which uses function graph tracing), the tracers are not
   closed properly during when the iterator sees the switch, and the
   wakeup function did not initialize its private pointer to NULL, which
   is used to know if the function graph tracer was the last tracer. It
   could be fooled in thinking it is, but then on exit it does not call
   the close function of the function graph tracer to clean up its data.

 - Fix synthetic events on big endian machines, by introducing a union
   that does the conversions properly.

 - Fix synthetic events from printing out the number of elements in the
   stacktrace when it shouldn't.

 - Fix synthetic events stacktrace to not print a bogus value at the
   end.

 - Introduce a pipe_cpumask that prevents the trace_pipe files from
   being opened by more than one task (file descriptor).

   There was a race found where if splice is called, the iter->ent could
   become stale and events could be missed. There's no point reading a
   producer/consumer file by more than one task as they will corrupt
   each other anyway. Add a cpumask that keeps track of the per_cpu
   trace_pipe files as well as the global trace_pipe file that prevents
   more than one open of a trace_pipe file that represents the same ring
   buffer. This prevents the race from happening.

 - Fix ftrace samples for arm64 to work with older compilers.

This PR contains nf_tables updates for your *net* tree.

validation state per table, reported by Pablo, fixup from myself.

Second patch makes sure objects waiting for memory release have been

Patch three is a fix-for-fix from previous PR: In case a transaction
gets aborted, gc sequence counter needs to be incremented so pending
gc requests are invalidated, from Pablo.

Same for patch 4: gc list needs to use gc list lock, not destroy lock,
also from Pablo.

Patch 5 fixes a UaF in a set backend, but this should only occur when
failslab is enabled for GFP_KERNEL allocations, broken since feature
was added in 5.6, from myself.

Patch 6 fixes a double-free bug that was also added via previous PR:

The commit 14af9963 ("bonding: Support macvlans on top of tlb/rlb mode
bonds") aims to enable the use of macvlans on top of rlb bond mode. However,
the current rlb bond mode only handles ARP packets to update remote neighbor
entries. This causes an issue when a macvlan is on top of the bond, and
remote devices send packets to the macvlan using the bond's MAC address
as the destination. After delivering the packets to the macvlan, the macvlan
will rejects them as the MAC address is incorrect. Consequently, this commit
makes macvlan over bond non-functional.

To address this problem, one potential solution is to check for the presence
of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev)
and return NULL in the rlb_arp_xmit() function. However, this approach
doesn't fully resolve the situation when a VLAN exists between the bond and
macvlan.

So let's just do a partial revert for commit 14af9963 in rlb_arp_xmit().
As the comment said, Don't modify or load balance ARPs that do not originate
locally.

ASoC: Fixes for v6.5

A relatively large but generally not super urgent set of fixes for ASoC,
including some quirks and a MAINTAINERS update.  There's also an update
to cs35l56 to change the firmware ABI, there are no current shipping
systems which use the current interface and the sooner we get the new
interface in the less likely it is that something will start.

It'd be nice if these landed for v6.5 but not the end of the world if
they wait till v6.6.

Pull ACPI fix from Rafael Wysocki:
 "Make an existing ACPI IRQ override quirk for PCSpecialist Elimina Pro
  16 M work as intended (Hans de Goede)"

  ACPI: resource: Fix IRQ override quirk for PCSpecialist Elimina Pro 16 M

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.

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.

For multiple commands the driver was not correctly validating the shader
stages resulting in possible kernel oopses. The validation code was only.
if ever, checking the upper bound on the shader stages but never a lower
bound (valid shader stages start at 1 not 0).

Don't queue more gc work, else we may queue the same elements multiple
times.

If an element is flagged as dead, this can mean that either the previous
gc request was invalidated/discarded by a transaction or that the previous
request is still pending in the system work queue.

The latter will happen if the gc interval is set to a very low value,
e.g. 1ms, and system work queue is backlogged.

The sets refcount is 1 if no previous gc requeusts are queued, so add
a helper for this and skip gc run if old requests are pending.

Add a helper for this and skip the gc run in this case.

Destroy work waits for the RCU grace period then it releases the objects
with no mutex held. All releases objects follow this path for
transactions, therefore, order is guaranteed and references to top-level
objects in the hierarchy remain valid.

However, netlink notifier might interfer with pending destroy work.
rcu_barrier() is not correct because objects are not release via RCU
callback. Flush destroy work before releasing objects from netlink
notifier path.

We have to validate all tables in the transaction that are in
VALIDATE_DO state, the blamed commit below did not move the break
statement to its right location so we only validate one table.

Moreover, we can't init table->validate to _SKIP when a table object
is allocated.

If we do, then if a transcaction creates a new table and then
fails the transaction, nfnetlink will loop and nft will hang until
user cancels the command.

Add back the pernet state as a place to stash the last state encountered.
This is either _DO (we hit an error during commit validation) or _SKIP
(transaction passed all checks).

When replacing an existing root qdisc, with one that is of the same kind, the
request boils down to essentially a parameterization change  i.e not one that
requires allocation and grafting of a new qdisc. syzbot was able to create a
scenario which resulted in a taprio qdisc replacing an existing taprio qdisc
with a combination of NLM_F_CREATE, NLM_F_REPLACE and NLM_F_EXCL leading to
create and graft scenario.
The fix ensures that only when the qdisc kinds are different that we should
allow a create and graft, otherwise it goes into the "change" codepath.

While at it, fix the code and comments to improve readability.

While syzbot was able to create the issue, it did not zone on the root cause.
Analysis from Vladimir Oltean <vladimir.oltean@nxp.com> helped narrow it down.

v1->V2 changes:
- remove "inline" function definition (Vladmir)
- remove extrenous braces in branches (Vladmir)
- change inline function names (Pedro)
- Run tdc tests (Victor)
v2->v3 changes:
- dont break else/if (Simon)

deadlock as the timeline_fence_release recurses onto the fence->lock

To avoid that, temporarily hold an extra reference to the signalled
