tools arch x86: Sync the msr-index.h copy with the kernel sources
To pick up the changes in:
5cde265384ca ("perf/x86/rapl: Add AMD Fam17h RAPL support")
Addressing this tools/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
With this one will be able to use these new AMD MSRs in filters, by
name, e.g.:
# perf trace -e msr:* --filter="msr==AMD_PKG_ENERGY_STATUS || msr==AMD_RAPL_POWER_UNIT"
Just like it is now possible with other MSRs:
[root@five ~]# uname -a

Longer explanation with what happens in the perf build process,
automatically after this is made in synch with the kernel sources:
