Linus Torvalds a0e4467726 asm-generic: asm/io.h rewrite
While there normally is no reason to have a pull request for asm-generic
 but have all changes get merged through whichever tree needs them, I do
 have a series for 3.19. There are two sets of patches that change
 significant portions of asm/io.h, and this branch contains both in order
 to resolve the conflicts:
 
 - Will Deacon has done a set of patches to ensure that all architectures
   define {read,write}{b,w,l,q}_relaxed() functions or get them by
   including asm-generic/io.h. These functions are commonly used on ARM
   specific drivers to avoid expensive L2 cache synchronization implied by
   the normal {read,write}{b,w,l,q}, but we need to define them on all
   architectures in order to share the drivers across architectures and
   to enable CONFIG_COMPILE_TEST configurations for them
 
 - Thierry Reding has done an unrelated set of patches that extends
   the asm-generic/io.h file to the degree necessary to make it useful
   on ARM64 and potentially other architectures.
