Merge tag 'arm-memremap-for-v4.7' of git://git.linaro.org/people/ard.biesheuvel/linux-arm into devel-stable
This series wires up the generic memremap() function for ARM in a way
that allows it to be used as intended, i.e., without regard for whether
the region being mapped is covered by a struct page and/or the linear
mapping (lowmem)
