These are a few cleanups for asm-generic:

Browse Source 
* 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.
