[PATCH 1/1] tools headers UAPI: Sync KVM's vmx.h with the kernel to pick SEAMCALL exit reason

[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:

  9d7dfb95da2cb5c1 ("KVM: VMX: Inject #UD if guest tries to execute SEAMCALL or TDCALL")

The 'perf kvm-stat' tool uses the exit reasons that are included in the
VMX_EXIT_REASONS define, this new SEAMCALL isn't included there (TDCALL
is), so shouldn't be causing any change in behaviour, this patch ends up
being just addressess the following perf build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/arch/x86/include/uapi/asm/vmx.h arch/x86/include/uapi/asm/vmx.h

Please see tools/include/uapi/README for further details.
