This updates the GPU headers to latest from mesa, using gen_header.py
(which is used to generate headers at bulid time for mesa), rather than
headergen2 (which doesn't have proper support for A6XX vs A7XX register

Mostly just uninteresting churn, but there are a couple spots in a7xx

("cpu_atom", "cpu_core") needs to be used as a prefix to be

'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

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.
