To pick up the changes introduced in:

  6fbbde9a ("KVM: x86: Control guest reads of MSR_PLATFORM_INFO")

That is not yet used in tools such as 'perf trace'.

The type of the change in this file, a simple integer parameter to the
KVM_CHECK_EXTENSION ioctl should be easier to implement tho, adding to
the libbeauty TODO list.

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h
