Message

Small batch of improvements for the 'Opt-in always-on nVHE hypervisor'
series, now merged in kvmarm/next.

Patch #1 fixes potential use of invalid v0.1 functions IDs reported
by Mark Rutland, patch #2 fixes a warning reported by Qian Cai.
Patch #3 avoids a code path not used in VHE, can be dropped if any
concerns arise. The remaining patches are minor cleanups from review.
