[PATCH v2 0/6] arm64/signal: Signal handling cleanups

[Mark Brown]

This series collects a number of small cleanups to the signal handling
code which removes redundant validation of size information and avoids
reading the same data from userspace twice.

There are some overlaps with both the TPIDR2 signal handling and SME2
serieses which are also in flight, applying this will require
adjustments in those serieses and vice versa.

v2:
 - Rebase onto v6.2-rc1
