Wei Yang	f6c6010a07	mm/resource: Use resource_overlaps() to simplify region_intersects() ... The three checks in region_intersects() are basically an open-coded version of resource_overlaps() - so use the real thing. Also fix typos in comments while at it.

Dan Williams	5981690ddb	memremap: split devm_memremap_pages() and memremap() infrastructure ... Currently, kernel/memremap.c contains generic code for supporting memremap() (CONFIG_HAS_IOMEM) and devm_memremap_pages() (CONFIG_ZONE_DEVICE). This causes ongoing build maintenance problems as additions to memremap.c, especially for the ZONE_DEVICE case, need to be careful about being placed in ifdef guards. Remove the need for these ifdef guards by moving the ZONE_DEVICE support functions to their own compilation unit.
