This series is a follow-up to Joey's Permission Overlay Extension (POE)
series [1] that recently landed on mainline. The goal is to improve the
way we handle the register that governs which pkeys/POIndex are
accessible (POR_EL0) during signal delivery. As things stand, we may
unexpectedly fail to write the signal frame on the stack because POR_EL0
is not reset before the uaccess operations. See patch 1 for more details
and the main changes this series brings.

Applied first patch to arm64 (for-next/fixes), thanks!
