This came out of a comment Russell made while reviewing RODATA test cases http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/480855.html While the final result of that series was the rodata code was refactored into its own header file, the set_memory_* APIs are still out of place. This version refactored the common set_memory_* functions into an asm-generic header. s390x added some features so it can't just use the asm-generic header. I debated how much more to try and shove into the asm-generic version (e.g. stub prototypes for the ARM nommu case, set_kernel_text_*) but decided to stick with just the basics for this version. I split out the cacheflush.h -> set_memory.h conversions into separate patches to hopefully make merging easier. Worst case, the final patch to completely separate the two can be delayed if there are more problems found. I'd like for this to eventually go through the -mm tree so I'd like Acks where appropriate. As always, feedback appreciated.
