Paolo, Radim,

This is the KVM/arm updates for Linux v5.1, much smaller than expected, as
most of the stuff we were hoping to queue missed the merge window. Oh well,
5.2 will be "interesting".

This time, we have a bunch of changes that prepare the landing of the some
of the nested virt code, some optimisations on the timer emulation (direct
assignment of the physical timer on VHE systems), some better type-safety
checks for the HYP code, Set/Way optimisations for silly 32bit guests, and a
bunch of cleanups here and there. Oh, and a MAINTAINERS update to officially
mention that we have a set of dedicated reviewers working with us!

Note that the first patch hits code that is outside of the KVM tree, but
that Daniel has agreed to us taking directly given that it was required for
a lot of other things in this drop.

Please pull,

	M.
