[v2,0/3] Device-memory-related cleanups

Message

Hi all,

This is essentially just a repost, with the trivial typo fix plus all
the acks/reviews collected. There's no direct dependency between the
patches here, so hopefully at least #1 and #3 might sneak into 5.2 if
there's still time, as that would save some bother for follow-up arm64
work next cycle which will depend on both.

Robin.

  mm/memremap: Rename and consolidate SECTION_SIZE
  mm: clean up is_device_*_page() definitions
