KVM: s390: KVM page table management functions: lifecycle management

Browse source

Add page table management functions to be used for KVM guest (gmap)
page tables.

This patch adds functions to handle memslot creation and destruction,
additional per-pagetable data stored in the PGSTEs, mapping physical
addresses into the gmap, and marking address ranges as prefix.
