Changes since v4 [1]: 1/ Squashed the pmem memremap conversion into one patch and dropped the boilerplate for looking a mapping-type by range. The architecture now optionally defines ARCH_MEMREMAP_PMEM flags to override the default. (Christoph)
2/ Fixed memunmap_pmem() to be devm based to match memremap_pmem() [1]: https://lists.01.org/pipermail/linux-nvdimm/2015-August/001728.html --- While developing the pmem driver we noticed that the __iomem annotation on the return value from ioremap_cache() was being mishandled by several callers. We also observed that all of the call sites expected to be able to treat the return value from ioremap_cache() as normal (non-__iomem) pointer to memory.
