Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic asm/io.h rewrite from Arnd Bergmann:
"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"
