  ARM: memremap: implement arch_memremap_wb() (2016-04-04 10:26:42 +0200)

----------------------------------------------------------------
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)

----------------------------------------------------------------
Ard Biesheuvel (4):
      ARM: reintroduce ioremap_cached() for creating cached I/O mappings
      mtd: pxa2xx-flash: switch back from memremap to ioremap_cached
      memremap: add arch specific hook for MEMREMAP_WB mappings
      ARM: memremap: implement arch_memremap_wb()
