Hi Catalin, Will,

Since James is on vacation, just want to ping if you could pick up
this two patches?  Mark.B has given review tags for this patch set.

I did this is because there has another patch set in perf tool to
enable SVE registsers [1], which is dependent on this patch set's
merging.

Thanks,
Leo
