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.
