[PATCH v3 0/4] Devmap cleanups + arm64 support

[Robin Murphy]

Hi all,

Here's a refresh of my devmap stuff, now including the end goal as
well. Patches #1 to #3 are just a rebase of v2, and I hope are ready to
be picked up in the mm tree (#1 is currently doing double-duty in Dan's
subsection series as well). Patch #4 could either go via mm if Will and
Catalin agree, or could go via arm64 with a small tweak to let it build
(but otherwise do nothing) until it meets up with #3 again.

Robin.


Robin Murphy (4):
  mm/memremap: Rename and consolidate SECTION_SIZE
  mm: clean up is_device_*_page() definitions
  mm: introduce ARCH_HAS_PTE_DEVMAP
  arm64: mm: Implement pte_devmap support
