Pull highmem initialization fix from Mike Rapoport:
"Fix highmem initialization on arm and xtensa
Recent refactoring of memblock iterators has broken initialization of
highmem on arm and xtensa because it changed the way beginning and end
of memory regions are rounded to PFNs. This fix restores the original
behaviour"

ARM, xtensa: highmem: avoid clobbering non-page aligned memory reservations
