Hi Greg,
Could you please revert
7212e37cbdf9 x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls
from 4.4-stable?
In 4.4-stable efi_runtime_lock as defined in drivers/firmware/efi/runtime-wrappers.c is a spinlock (given it predates commit dce48e351c0d) and commit
f331e766c4be x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls
which 7212e37cbdf9 is a backport of, needs it to be a semaphore.
Cheers, Hedi.

I've queued up the revert. I'm not sure how it ended up on 4.4 to begin with; sorry about that and thank you.
