  perf cap: Add __NR_capget to arch/x86 unistd (2024-10-28 13:04:52 -0300)

----------------------------------------------------------------
perf tools fixes for v6.12: 2nd batch

- Update more header copies with the kernel sources, including const.h,
  msr-index.h, arm64's cputype.h, kvm's, bits.h and unaligned.h

- The return from 'write' isn't a pid, fix cut'n'paste error in 'perf
  trace'.

- Fix up the python binding build on architectures without
  HAVE_KVM_STAT_SUPPORT.

- Add some more bounds checks to augmented_raw_syscalls.bpf.c (used to
  collect syscall pointer arguments in 'perf trace') to make the
  resulting bytecode to pass the kernel BPF verifier, allowing us to go
  back accepting clang 12.0.1 as the minimum version required for
  compiling BPF sources.

- Add __NR_capget for x86 to fix a regression on running perf + intel PT
  (hw tracing) as non-root setting up the capabilities as described in
  https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html.

- Fix missing syscalltbl in non-explicitly listed architectures, noticed
  on ARM 32-bit, that still needs a .tbl generator for the syscall
  id<->name tables, should be added for v6.13.

- Handle 'perf test' failure when handling broken DWARF for ASM files.
