[Qemu-ppc] [PATCHv2 for-2.13 0/2] Helpers to obtain host page sizes for guest RAM

[David Gibson]

This series makes some small changes to make it easier to obtain the
host page size backing given portions of guest RAM.  We use this in a
couple of places currently, and I have one or two more to add in some
upcoming code.

Changes since v1:
  * Reworked design based on Eduardo's feedback
  * Split into two patches

David Gibson (2):
  Make qemu_mempath_getpagesize() accept NULL
  Add host_memory_backend_pagesize() helper
