[PATCH 1/1 fyi] tools headers x86 svm: Sync svm headers with the kernel sources

[Arnaldo Carvalho de Melo]

tldr; Just FYI, I'm carrying this on the perf tools tree.

Full explanation:

There used to be no copies, with tools/ code using kernel headers
directly. From time to time tools/perf/ broke due to legitimate kernel
hacking. At some point Linus complained about such direct usage. Then we
adopted the current model.

See further details at:

 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/include/uapi/README

To pick the changes in:

  827547bc3a2a2af6 ("KVM: SVM: Add architectural definitions/assets for Bus Lock Threshold")

That triggers:

  CC      /tmp/build/perf-tools/arch/x86/util/kvm-stat.o
  LD      /tmp/build/perf-tools/arch/x86/util/perf-util-in.o
  LD      /tmp/build/perf-tools/arch/x86/perf-util-in.o
  LD      /tmp/build/perf-tools/arch/perf-util-in.o
  LD      /tmp/build/perf-tools/perf-util-in.o
  AR      /tmp/build/perf-tools/libperf-util.a
  LINK    /tmp/build/perf-tools/perf

The SVM_EXIT_BUS_LOCK exit reason was added to SVM_EXIT_REASONS, used in
kvm-stat.c.

This addresses this perf build warning:
