None entails changes in tooling, the closest to that were some new arch
specific ioctls, that are still not handled by the tools/perf/trace/beauty/
library, that needs to create per-arch tables to convert ioctl cmd->string (and
back).
>From a quick look the arch specific kvm-stat.c files at:
$ ls -1 tools/perf/arch/*/util/kvm-stat.c
tools/perf/arch/powerpc/util/kvm-stat.c
tools/perf/arch/s390/util/kvm-stat.c
tools/perf/arch/x86/util/kvm-stat.c
$
Are not affected.
