Paolo,

This is the second batch of KVM/arm fixes for 5.7. A compilation fix,
a GICv4.1 fix, plus a couple of sanity checks (SP_EL0 save/restore,
and the sanitising of AArch32 registers).

Note that the pull request I sent a week ago[1] is still valid, and
that this new series is built on top of the previous one.

Please pull,

	M.
