Replace the now deprecated kmap_atomic() with kmap_local_page(). Optimizing nvdimm/pmem for highmem makes no sense as this is always 64bit, and the mapped regions for both btt and pmem do not require disabling preemption and pagefaults. Specifically, kmap does not care about the caller's atomic context (such as reads holding the btt arena spinlock) or NVDIMM_IO_ATOMIC semantics to avoid error handling when accessing the btt arena in general. Same for the memcpy cases. kmap local temporary mappings will hold valid across any context switches.
