[PATCH v3 0/4] KVM: s390: Fixes for gmap and _PAGE_UNUSED

[Claudio Imbrenda]

Fix handling of _PAGE_UNUSED pte bit. The bit was lingering around
longer than it should have, causing issues. This is yet a different
approach from the previous version.

Also fix a few other small issues in gmap.

v2->v3:
* Fix _PAGE_UNUSED in yet a different way
* Fix a potential overflow in dat_peek_cmma()
* Some minor gmap fixes that are not actual bugs yet

v1->v2:
* Completely different approach, entirely new patch
