Most of this series only repaints things so that VHE and nVHE look as
similar as possible, the ZCR_EL2 management being the most visible
exception. This results in a bunch of preparatory patches that aim at
making the code slightly more readable.

That readability stuff is definitely helping from my PoV.

(FWIW, from the SVE side)

This has been tested on a FVP model with both VHE/nVHE configurations
using the string tests included with the "optimized-routines"
library[2].

There's also some tests Dave wrote which got upstreamed in kselftest
now, some normal kselftests and also a stress test that sits and
writes/reads bit patterns into the registers and is pretty good at
picking up any context switch issues.
