Arnaldo Carvalho de Melo 40f1c039c7 tools arch x86: Sync asm/cpufeatures.h with the kernel sources 
To pick up the changes from:

  b4dd4f6e36 ("x86/vmware: Add a header file for hypercall definitions")
  f36cf386e3 ("x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS")
  be261ffce6 ("x86: Remove X86_FEATURE_MFENCE_RDTSC")
  018ebca8bd ("x86/cpufeatures: Enable a new AVX512 CPU feature")

These don't cause any changes in tooling, just silences this perf build
warning:

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

To clarify, updating those files cause these bits of tools/perf to rebuild:

  CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
  CC       /tmp/build/perf/bench/mem-memset-x86-64-asm.o
  INSTALL  GTK UI
  LD       /tmp/build/perf/bench/perf-in.o

Those use just:

  $ grep FEATURE tools/arch/x86/lib/mem*.S
  tools/arch/x86/lib/memcpy_64.S:	ALTERNATIVE_2 "jmp memcpy_orig", "", X86_FEATURE_REP_GOOD, \
  tools/arch/x86/lib/memcpy_64.S:		      "jmp memcpy_erms", X86_FEATURE_ERMS
  tools/arch/x86/lib/memset_64.S:	ALTERNATIVE_2 "jmp memset_orig", "", X86_FEATURE_REP_GOOD, \
  tools/arch/x86/lib/memset_64.S:		      "jmp memset_erms", X86_FEATURE_ERMS
  $

I.e. none of the feature defines added/removed by the patches above.

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.
