Merge tag 'asm-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm...

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
