efi_rs_enter() and efi_rs_leave() look very PV x86 specific. It is
possible that we don't actually need to do anything at all on ARM, aside
from refactoring the code. Jan?
Similarly we don't have an rtc_lock spinlock today and it is not
actually needed, but for the sake of keeping the common code common, I
would just introduce rtc_lock on ARM too.
