Add PKEY support to signals, by saving and restoring POR_EL0 from the stackframe.
It'd be nice to have at least a basic test that validates that we generate a POE signal frame when expected, though that should be a very minor thing which is unlikely to ever actually spot anything.
I'd also expect to see matching support added to ptrace.
The selftests/mm/protection_keys.c looks for the POE signal frame, do you think we need a separate test?
I will look into ptrace.
Thanks, Joey
