hda_generic_machine_select() appends -idisp to the tplg filename by
allocating a new string with devm_kasprintf(), then stores the string
right back into the global variable snd_soc_acpi_intel_hda_machines.
When the module is unloaded, this memory is freed, resulting in a global
variable pointing to freed memory.  Reloading the module then triggers
a use-after-free:

…to software cursor"

This reverts commit 272e6aa.

Applying degamma curve to the cursor by default breaks Linux userspace
expectation.

On Linux, AMD display manager enables cursor degamma ROM just for
implict sRGB on HW versions where degamma is split into two blocks:
degamma ROM for pre-defined TFs and `gamma correction` for user/custom
curves, and degamma ROM settings doesn't apply to cursor plane.

Context Timestamp (CTX_TIMESTAMP) in the LRC accumulates the run ticks
of the context, but only gets updated when the context switches out. In
order to check how long a context has been active before it switches
out, two things are required:

(1) Determine if the context is running:

To do so, we program the WA BB to set an initial value for CTX_TIMESTAMP
in the LRC. The value chosen is 1 since 0 is the initial value when the
LRC is initialized. During a query, we just check for this value to
determine if the context is active. If the context switched out, it
would overwrite this location with the actual CTX_TIMESTAMP MMIO value.
Note that WA BB runs as the last part of the context restore, so reusing
this LRC location will not clobber anything.

(2) Calculate the time that the context has been active for:

The CTX_TIMESTAMP ticks only when the context is active. If a context is
active, we just use the CTX_TIMESTAMP MMIO as the new value of
utilization. While doing so, we need to read the CTX_TIMESTAMP MMIO
for the specific engine instance. Since we do not know which instance
the context is running on until it is scheduled, we also read the
ENGINE_ID MMIO in the WA BB and store it in the PPHSWP.

Using the above 2 instructions in a WA BB, capture active context
utilization.

v2: (Matt Brost)
- This breaks TDR, fix it by saving the CTX_TIMESTAMP register
  "drm/xe: Save CTX_TIMESTAMP mmio value instead of LRC value"
- Drop tile from LRC if using gt
  "drm/xe: Save the gt pointer in LRC and drop the tile"

v3:
- Remove helpers for bb_per_ctx_ptr (Matt)
- Add define for context active value (Matt)
- Use 64 bit CTX TIMESTAMP for platforms that support it. For platforms
  that don't, live with the rare race. (Matt, Lucas)
- Convert engine id to hwe and get the MMIO value (Lucas)
- Correct commit message on when WA BB runs (Lucas)

v4:
- s/GRAPHICS_VER(...)/xe->info.has_64bit_timestamp/ (Matt)
- Drop support for active utilization on a VF (CI failure)
- In xe_lrc_init ensure the lrc value is 0 to begin with (CI regression)

v5:
- Minor checkpatch fix
- Squash into previous commit and make TDR use 32-bit time
- Update code comment to match commit msg

When using the stacktrace trigger command to trace syscalls, the
preemption count was consistently reported as 1 when the system call
event itself had 0 (".").

For example:

root@ubuntu22-vm:/sys/kernel/tracing/events/syscalls/sys_enter_read
$ echo stacktrace > trigger
$ echo 1 > enable

    sshd-416     [002] .....   232.864910: sys_read(fd: a, buf: 556b1f3221d0, count: 8000)
    sshd-416     [002] ...1.   232.864913: <stack trace>
 => ftrace_syscall_enter
 => syscall_trace_enter
 => do_syscall_64
 => entry_SYSCALL_64_after_hwframe

The root cause is that the trace framework disables preemption in __DO_TRACE before
invoking the trigger callback.

Use the tracing_gen_ctx_dec() that will accommodate for the increase of
the preemption count in __DO_TRACE when calling the callback. The result
is the accurate reporting of:

    sshd-410     [004] .....   210.117660: sys_read(fd: 4, buf: 559b725ba130, count: 40000)

The ring buffer is made up of sub buffers (sometimes called pages as they
are by default PAGE_SIZE). It has the following "pages":

  "tail page" - this is the page that the next write will write to
  "head page" - this is the page that the reader will swap the reader page with.
  "reader page" - This belongs to the reader, where it will swap the head
                  page from the ring buffer so that the reader does not
                  race with the writer.

The writer may end up on the "reader page" if the ring buffer hasn't
written more than one page, where the "tail page" and the "head page" are
the same.

The persistent ring buffer has meta data that points to where these pages
exist so on reboot it can re-create the pointers to the cpu_buffer
descriptor. But when the commit page is on the reader page, the logic is
incorrect.

The check to see if the commit page is on the reader page checked if the
head page was the reader page, which would never happen, as the head page
is always in the ring buffer. The correct check would be to test if the
commit page is on the reader page. If that's the case, then it can exit
out early as the commit page is only on the reader page when there's only
one page of data in the buffer. There's no reason to iterate the ring
buffer pages to find the "commit page" as it is already found.

To trigger this bug:

  # echo 1 > /sys/kernel/tracing/instances/boot_mapped/events/syscalls/sys_enter_fchownat/enable
  # touch /tmp/x
  # chown sshd /tmp/x
  # reboot

On boot up, the dmesg will have:
 Ring buffer meta [0] is from previous boot!
 Ring buffer meta [1] is from previous boot!
 Ring buffer meta [2] is from previous boot!
 Ring buffer meta [3] is from previous boot!
 Ring buffer meta [4] commit page not found
 Ring buffer meta [5] is from previous boot!
 Ring buffer meta [6] is from previous boot!
 Ring buffer meta [7] is from previous boot!

Where the buffer on CPU 4 had a "commit page not found" error and that
buffer is cleared and reset causing the output to be empty and the data lost.

When it works correctly, it has:

  # cat /sys/kernel/tracing/instances/boot_mapped/trace_pipe
        <...>-1137    [004] .....   998.205323: sys_enter_fchownat: __syscall_nr=0x104 (260) dfd=0xffffff9c (4294967196) filename=(0xffffc90000a0002c) user=0x3e8 (1000) group=0xffffffff (4294967295) flag=0x0 (0

Pull tracing fixes from Steven Rostedt:

 - Fix sample code that uses trace_array_printk()

   The sample code for in kernel use of trace_array (that creates an
   instance for use within the kernel) and shows how to use
   trace_array_printk() that writes into the created instance, used
   trace_printk_init_buffers(). But that function is used to initialize
   normal trace_printk() and produces the NOTICE banner which is not
   needed for use of trace_array_printk(). The function to initialize
   that is trace_array_init_printk() that takes the created trace array
   instance as a parameter.

   Update the sample code to reflect the proper usage.

 - Fix preemption count output for stacktrace event

   The tracing buffer shows the preempt count level when an event
   executes. Because writing the event itself disables preemption, this
   needs to be accounted for when recording. The stacktrace event did
   not account for this so the output of the stacktrace event showed
   preemption was disabled while the event that triggered the stacktrace

   The same happened for stack traces triggered by function tracer.

 - Fix persistent ring buffer when trace_pipe is used

   The ring buffer swaps the reader page with the next page to read from
   the write buffer when trace_pipe is used. If there's only a page of
   data in the ring buffer, this swap will cause the "commit" pointer
   (last data written) to be on the reader page. If more data is written
   to the buffer, it is added to the reader page until it falls off back
   into the write buffer.

   If the system reboots and the commit pointer is still on the reader
   page, even if new data was written, the persistent buffer validator
   will miss finding the commit pointer because it only checks the write
   buffer and does not check the reader page. This causes the validator
   to fail the validation and clear the buffer, where the new data is
   lost.

   There was a check for this, but it checked the "head pointer", which
   was incorrect, because the "head pointer" always stays on the write
   buffer and is the next page to swap out for the reader page. Fix the
   logic to catch this case and allow the user to still read the data
   after reboot.

Evacuate walks btree nodes with bch2_btree_iter_next_node() and rewrites
them, bch2_btree_update_start() upgrades the path to take intent locks
as far as it needs to.

But next_node() does low level unlock/relock calls on individual nodes,
and didn't handle the case where a path is supposed to be holding
multiple intent locks. If a path has locks_want > 1, it needs to be
either holding locks on all the btree nodes (at each level) requested,
or none of them.

Fix this with a bch2_btree_path_downgrade().

When the journal is low on space, we might do discards from
journal_res_get() -> journal_entry_open().

Make sure we set j->can_discard correctly, so that if we're low on space
but not because discards aren't keeping up we don't livelock.

Prevent jobs that do lots of scanning (i.e. evacuatee, scrub) from
causing OOMs.

The shrinker code seems to be having issues when it doesn't do any
freeing because it's just flipping off the acccessed bit - and the
accessed bit shouldn't be set on first use anyways.

Fsck wants to do transaction commits from an outer context; it may have
other repair to do (i.e. duplicate backpointers).

But when calling backpointer_not_found() from runtime code, i.e. runtime
self healing, we should be doing the commit - the outer context expects
to just be doing lookups.

This fixes bugs where we get stuck spinning, reported as "RCU lock hold
time warnings.

The response buffer for the CREATE request handled by smb311_posix_mkdir()
is leaked on the error path (goto err_free_rsp_buf) because the structure
pointer *rsp passed to free_rsp_buf() is not assigned until *after* the
error condition is checked.

As *rsp is initialised to NULL, free_rsp_buf() becomes a no-op and the leak
is instead reported by __kmem_cache_shutdown() upon subsequent rmmod of
cifs.ko if (and only if) the error path has been hit.

Pass rsp_iov.iov_base to free_rsp_buf() instead, similar to the code in
other functions in smb2pdu.c for which *rsp is assigned late.

cifs_prepare_read() might be called with a disconnected channel, where
TCP_Server_Info::max_read is set to zero due to reconnect, so calling
->negotiate_rize() will set @rsize to default min IO size (64KiB) and
then logging

	CIFS: VFS: SMB: Zero rsize calculated, using minimum value
	65536

If the reconnect happens in cifsd thread, cifs_renegotiate_iosize()
will end up being called and then @rsize set to the expected value.

Since we can't rely on the value of @server->max_read by the time we
call cifs_prepare_read(), try to ->negotiate_rize() only if
@cifs_sb->ctx->rsize is zero.

ASoC: Fixes for v6.15

A couple more small fixes for v6.15, both of which could also easily
wait until the merge window.
In commit d69d804 ("driver core: have match() callback in struct
bus_type take a const *"), the match bus callback was changed to have
the driver be a const pointer.  Unfortunately that const attribute was
thrown away when container_of() is called, which is not correct and was
not caught by the compiler due to how container_of() is implemented.
Fix this up by correctly preserving the const attribute of the driver
passed to the bus match function which requires the hdac_driver match
function to also take a const pointer for the driver structure.

ASoC: Updates for v6.16

The changes in this release are quite large, mainly in drivers rather
than the core.  This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.

 - Support for automatically enumerating DAIs from standards conforming
   SoundWire SDCA devices, further work is required for these to be
   useful in an actual card.
 - Conversion of quite a few drivers to newer GPIO APIs.
 - More helpers and cleanups from Mormimoto-san.
 - Support for a wider range of AVS platforms.
 - Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32,
   Everest Semiconductor ES8389, Longsoon-1 AC'97 controllers, nVidia
   Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers.
Sync with the pending 6.15 fixes.

The dev_pm_ops definition must be SYSTEM_SLEEP_PM_OPS() instead of
SET_SYSTEM_SLEEP_PM_OPS(); otherwise it leads compile warnings without
CONFIG_PM_SLEEP.  The latest patch version I took was back to an old
macro (likely mistakenly), and I overlooked it at applying.  Fix it
now.
