414d3b0749 s390/kvm: page table invalidation notifier 
Pass an address range to the page table invalidation notifier
for KVM. This allows to notify changes that affect a larger
virtual memory area, e.g. for 1MB pages.

9c650d09a9 s390/mm/kvm: fix mis-merge in gmap handling 
commit 1e133ab296 ("s390/mm: split arch/s390/mm/pgtable.c") dropped
some changes from commit a3a92c31bf ("KVM: s390: fix mismatch
between user and in-kernel guest limit") - this breaks KVM for some
memory sizes (kvm-s390: failed to commit memory region) like
exactly 2GB.

1e133ab296 s390/mm: split arch/s390/mm/pgtable.c 
The pgtable.c file is quite big, before it grows any larger split it
into pgtable.c, pgalloc.c and gmap.c. In addition move the gmap related
header definitions into the new gmap.h header and all of the pgste
helpers from pgtable.h to pgtable.c.
