Arnaldo Carvalho de Melo e9bde94f1e tools arch x86: Sync the msr-index.h copy with the kernel sources 
To pick up the changes in:

  d205e0f142 ("x86/{cpufeatures,msr}: Add Intel SGX Launch Control hardware bits")
  e7b6385b01 ("x86/cpufeatures: Add Intel SGX hardware bits")
  43756a2989 ("powercap: Add AMD Fam17h RAPL support")
  298ed2b31f ("x86/msr-index: sort AMD RAPL MSRs by address")
  68299a42f8 ("x86/mce: Enable additional error logging on certain Intel CPUs")

That cause these changes in tooling:

  $ cp arch/x86/include/asm/msr-index.h tools/arch/x86/include/asm/msr-index.h

Which causes these parts of tools/perf/ to be rebuilt:

  CC       /tmp/build/perf/trace/beauty/tracepoints/x86_msr.o
  LD       /tmp/build/perf/trace/beauty/tracepoints/perf-in.o
  LD       /tmp/build/perf/trace/beauty/perf-in.o
  LD       /tmp/build/perf/perf-in.o
  LINK     /tmp/build/perf/perf

At some point these should just be tables read by perf on demand.

This allows 'perf trace' users to use those strings to translate from
the msr ids provided by the msr: tracepoints.

This addresses this perf tools build warning:

  diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
  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'

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
