Hi all,

these two patches simplify the xfs/iomap page fault path.  They came up in
the context of MAP_SYNC support, but are useful on their own, and might be
good to get into 4.14 before the real MAP_SYNC work starts hitting the
tree in some form.

Changes since V1:
 - drop the incorrect pfn consolidation
