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
