tools arch x86: Sync the msr-index.h copy with the kernel sources
To pick up the changes from these csets:
1b5277c0ea0b2473 ("x86/srso: Add SRSO_NO support")
8974eb588283b7d4 ("x86/speculation: Add Gather Data Sampling mitigation")
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 differences:
