drm/amd/display: Implement bounds check for stream encoder creation in DCN301
'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.
The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior
Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.
Thus fixing Buffer overflow error in dcn301_stream_encoder_create

Previously we would call apply_ctx_to_hw to enable and disable
phantom pipes. However, apply_ctx_to_hw can potentially update
non-phantom pipes as well which is undesired. Instead of calling
apply_ctx_to_hw as a whole, call the relevant helpers for each
phantom pipe when enabling / disabling which will avoid us modifying
hardware state for non-phantom pipes unknowingly.
The use case is for an FRL display where FRL_Update is requested
by the display. In this case link_state_valid flag is cleared in
a passive callback thread and should be handled in the next stream /
link update. However, due to the call to apply_ctx_to_hw for the
phantom pipes during a flip, the main pipes were modified outside
of the desired sequence (driver does not handle link_state_valid = 0
on flips).

When populating dml pipes, odm combine policy should be assigned based
on the pipe topology of the context passed in. DML pipes could be
repopulated multiple times during single validate bandwidth attempt. We
need to make sure that whenever we repopulate the dml pipes it is always
aligned with the updated context. There is a case where DML pipes get
repopulated during FPO optimization after ODM combine policy is changed.
Since in the current code we reinitlaize ODM combine policy, even though
the current context has ODM combine enabled, we overwrite it despite the
pipes are already split. This causes DML to think that MPC combine is
used so we mistakenly enable MPC combine because we apply pipe split
with ODM combine policy reset. This issue doesn't impact non windowed
MPO with ODM case because the legacy policy has restricted use cases. We
don't encounter the case where both ODM and FPO optimizations are
enabled together. So we decide to leave it as is because it is about to
be replaced anyway.

("cpu_atom", "cpu_core") needs to be used as a prefix to be
considered on a metric formula, detected via one of the 'perf test'
entries.
'perf test' fixes:
- Fix the creation of event selector lists on 'perf test' entries, by
initializing the sample ID flag, which is done by 'perf record', so
this fix affects only the tests, the common case isn't affected
- Make 'perf list' respect debug settings (-v) to fix its 'perf test'
entry
- Fix 'perf script' test when python support isn't enabled
- Special case 'perf script' tests on s390, where only DWARF call
graphs are supported and only on software events
- Make 'perf daemon' signal test less racy
Compiler warnings/errors:
- Remove needless malloc(0) call in 'perf top' that triggers
-Walloc-size
- Fix calloc() argument order to address error introduced in gcc-14
Build:
- Make minimal shellcheck version to v0.6.0, avoiding the build to
fail with older versions
Sync kernel header copies:
- stat.h to pick STATX_MNT_ID_UNIQUE
- msr-index.h to pick IA32_MKTME_KEYID_PARTITIONING

Merge tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing and eventfs fixes from Steven Rostedt:
- Fix the return code for ring_buffer_poll_wait()
It was returing a -EINVAL instead of EPOLLERR.
- Zero out the tracefs_inode so that all fields are initialized.
The ti->private could have had stale data, but instead of just
initializing it to NULL, clear out the entire structure when it is
allocated.
- Fix a crash in timerlat
The hrtimer was initialized at read and not open, but is canceled at
close. If the file was opened and never read the close will pass a
NULL pointer to hrtime_cancel().
- Rewrite of eventfs.
Linus wrote a patch series to remove the dentry references in the
eventfs_inode and to use ref counting and more of proper VFS
interfaces to make it work.
- Add warning to put_ei() if ei is not set to free. That means
something is about to free it when it shouldn't.
- Restructure the eventfs_inode to make it more compact, and remove the
unused llist field.
- Remove the fsnotify*() funtions for when the inodes were being
created in the lookup code. It doesn't make sense to notify about
creation just because something is being looked up.
- The inode hard link count was not accurate.
It was being updated when a file was looked up. The inodes of
directories were updating their parent inode hard link count every
time the inode was created. That means if memory reclaim cleaned a
stale directory inode and the inode was lookup up again, it would
increment the parent inode again as well. Al Viro said to just have
all eventfs directories have a hard link count of 1. That tells user
space not to trust it.
