Pulled, thanks a lot Arnaldo!
Note that I've applied the trivial header sync patch below on top of it to reduce
the number of build time warnings.
There's one warning left:
Warning: Kernel ABI header at 'tools/arch/x86/lib/memcpy_64.S' differs from latest version at 'arch/x86/lib/memcpy_64.S'
Which is a bit more involved as it requires the introduction of x86/asm/mcsafe_test.h
on the tooling side.
Thanks,
Ingo

Subject: [PATCH] tools/headers: Pick up latest kernel ABIs
Sync KVM ABI additions and x86 CPU features additions - neither of which
has any impact on the tooling build.
