Changes since v3: [1] 1/ Include devm_memremap() support (Christoph)
2/ Rebase the series to defer the removal of ioremap_cache() and drop any of the ioremap_cache()-to-memremap() conversions that have yet to be acked by the appropriate maintainer. This avoids any potential for bisection breakage during the 4.3 merge and the cleanup can be done for 4.4. (Christoph) [1]: https://lists.01.org/pipermail/linux-nvdimm/2015-July/001649.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.
