Arnaldo Carvalho de Melo 32b734e09e tools arch x86: Sync the msr-index.h copy with the kernel sources 
To pick up the changes in:

  29dcc60f6a ("x86/boot/compressed/64: Add stage1 #VC handler")
  36e1be8ada ("perf/x86/amd/ibs: Fix raw sample data accumulation")
  59a854e2f3 ("perf/x86/intel: Support TopDown metrics on Ice Lake")
  7b2c05a15d ("perf/x86/intel: Generic support for hardware TopDown metrics")
  99e40204e0 ("x86/msr: Move the F15h MSRs where they belong")
  b57de6cd16 ("x86/sev-es: Add SEV-ES Feature Detection")
  ed7bde7a6d ("cpufreq: intel_pstate: Allow enable/disable energy efficiency")
  f0f2f9feb4 ("x86/msr-index: Define an IA32_PASID MSR")

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
  DESCEND  plugins
  GEN      /tmp/build/perf/python/perf.so
  INSTALL  trace_plugins

  LD       /tmp/build/perf/trace/beauty/perf-in.o
  LD       /tmp/build/perf/perf-in.o
  LINK     /tmp/build/perf/per

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

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.
