mm: Call update_mmu_cache_range() in more page fault handling paths

filemap: Batch PTE mappings

Call set_pte_range() once per contiguous range of the folio instead
of once per page.  This batches the updates to mm counters and the
rmap.

With a will-it-scale.page_fault3 like app (change file write
fault testing to read fault testing. Trying to upstream it to
will-it-scale at [1]) got 15% performance gain on a 48C/96T
Cascade Lake test box with 96 processes running against xfs.

Perf data collected before/after the change:
  18.73%--page_add_file_rmap
