Please avoid queuing these patches -- the first is already in the arm64
queue for 4.5 and the second was found to introduce a substantial
performance regression on the syscall entry/exit path. I think Mark had
an updated version to address that, so it would be easier not to have
an old version sitting in some other queue!

Cheers,

Will
