<title>tools headers UAPI: Sync files changed by landlock, quotactl_path and mount_settattr new syscalls</title>

<id>f8bcb061ea013a9b39a071b9dd9f6ea0aa2caf72</id>
<content type='text'>
To pick the changes in these csets:

  a49f4f81cb48925e ("arch: Wire up Landlock syscalls")
  2a1867219c7b27f9 ("fs: add mount_setattr()")
  fa8b90070a80bb1a ("quota: wire up quotactl_path")

That silences these perf build warnings and add support for those new
syscalls in tools such as 'perf trace'.

For instance, this is now possible:

  # ~acme/bin/perf trace -v -e landlock*
  event qualifier tracepoint filter: (common_pid != 129365 &amp;&amp; common_pid != 3502) &amp;&amp; (id == 444 || id == 445 || id == 446)
  ^C#

That is tha filter expression attached to the raw_syscalls:sys_{enter,exit}
tracepoints.

  $ grep landlock tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
  444	common	landlock_create_ruleset	sys_landlock_create_ruleset
  445	common	landlock_add_rule	sys_landlock_add_rule
  446	common	landlock_restrict_self	sys_landlock_restrict_self
  $

This addresses these perf build warnings:

Map perf APIs (perf_reg_name/get_arch_regstr/unwind__arch_reg_id) with
MIPS specific registers.

[ayan@wavecomp.com: repick this patch for unwinding userstack backtrace
by perf and libunwind on MIPS based CPU.]

[yangtiezhu@loongson.cn: Add sample_reg_masks[] to fix build error,
silence some checkpatch errors and warnings, and also separate the
original patches into two parts (MIPS kernel and perf tools) to merge
easily.]

The original patches:

https://lore.kernel.org/patchwork/patch/1126520/

Committer notes:

Do it as __perf_reg_name() to cope with:

Support the MIPS architecture using the ins_ops association method. With
this patch, perf-annotate can work well on MIPS.

<title>perf tools: Add empty Build files for architectures lacking them</title>

perf currently fails to build on MIPS as there is no
tools/perf/arch/mips/Build file.  Adding an empty file fixes this as
there are no MIPS-specific sources to build.

It looks like the same is needed for Alpha and PA-RISC, though I
haven't been able to test those.
