Subject: [PATCH 08/73] tools x86 uapi asm: Sync the pt_regs.h copy with the kernel sources

From: Arnaldo Carvalho de Melo <acme@...hat.com>

To get the changes in:

  878068ea270e ("perf/x86: Support outputting XMM registers")

That will be used in a followup patch to allow users to ask for some or
all of those registers to be collected in certain contatexts.

This silences the following perf build warning:

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