…git/arnd/asm-generic Pull asm-generic cleanup from Arnd Bergmann: "These are a few cleanups for asm-generic: - a set of patches from Lars-Peter Clausen to generalize asm/mmu.h and use it in the architectures that don't need any special handling. - A patch from Will Deacon to remove the {read,write}s{b,w,l} as discussed during the arm64 review - A patch from James Hogan that helps with the meta architecture series." * tag 'asm-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: xtensa: Use generic asm/mmu.h for nommu h8300: Use generic asm/mmu.h c6x: Use generic asm/mmu.h asm-generic/mmu.h: Add support for FDPIC asm-generic/mmu.h: Remove unused vmlist field from mm_context_t asm-generic: io: remove {read,write} string functions asm-generic/io.h: remove asm/cacheflush.h include
