mm/follow_page_mask: split follow_page_mask to smaller functions.

Browse source

Makes code reading easy.  No functional changes in this patch.  In a
followup patch, we will be updating the follow_page_mask to handle
hugetlb hugepd format so that archs like ppc64 can switch to the generic
version.  This split helps in doing that nicely.
