[PATCH 5.15 85/89] tools arch x86: Sync the msr-index.h copy with the kernel sources

[Greg Kroah-Hartman]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

commit 91d248c3b903b46a58cbc7e8d38d684d3e4007c2 upstream.

To pick up the changes from these csets:

  4ad3278df6fe2b08 ("x86/speculation: Disable RRSBA behavior")
  d7caac991feeef1b ("x86/cpu/amd: Add Spectral Chicken")

That cause no changes to tooling:

  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > before
  $ cp arch/x86/include/asm/msr-index.h tools/arch/x86/include/asm/msr-index.h
  $ tools/perf/trace/beauty/tracepoints/x86_msr.sh > after
  $ diff -u before after
  $

Just silences this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/msr-index.h' differs from latest version at 'arch/x86/include/asm/msr-index.h'
  diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
