The changes in the 3214d01f ("KVM: PPC: Book3S: Provide information
about hardware/firmware CVE workarounds") commit right now will not
produce any change in the tools, but that is because we still need to
improve tools/perf/trace/beauty/kvm_ioctl.sh to build per arch string
tables, so that we avoid assigning multiple times to the same command
string entry, i.e. multiple defines, for different arches, have the same
value, causing this:

  In file included from trace/beauty/ioctl.c:82:0:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c: In function ‘ioctl__scnprintf_kvm_cmd’:
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:76:11: error: initialized field overwritten [-Werror=override-init]
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:88:11: note: (near initialization for ‘kvm_ioctl_cmds[165]’)
  /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c:90:11: error: initialized field overwritten [-Werror=override-init]
    [0xa6] = "PPC_GET_SMMU_INFO",
             ^~~~~~~~~~~~~~~~~~~

So the onlye effect of updating the tools/ copy of ppc's kvm.h header
is to silence these perf build warnings:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  Warning: Kernel ABI header at 'tools/arch/powerpc/include/uapi/asm/kvm.h' differs from latest version at 'arch/powerpc/include/uapi/asm/kvm.h'

At some point we should do what we did for the errno tables and create
per-arch string translation tables for the KVM ioctl commands for the
architectures supporting KVM, such as s/390, PowerPC, x86_64 and ARM.
