    tools headers UAPI: Sync linux/kvm.h with the kernel sources

    To pick the changes in:

      da142f3d373a6dda ("KVM: Remove subtle "struct kvm_stats_desc" pseudo-overlay")

    That just rebuilds perf, as these patches don't add any new KVM ioctl to
    be harvested for the 'perf trace' ioctl syscall argument beautifiers.

    This addresses this perf build warning:

      Warning: Kernel ABI header differences:
        diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h

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