Subject: mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h
X-Git-Tag: v4.3-rc1~50^2~6
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-linux.git;a=commitdiff_plain;h=012dcef3f058385268630c0003e9b7f8dcafbeb4

mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h

Three architectures already define these, and we'll need them genericly
soon.
