The kmap infrastructure has been copied almost verbatim to every architecture.
This series consolidates obvious duplicated code by defining core functions
which call into the architectures only when needed.

Some of the k[un]map_atomic() implementations have some similarities but the
similarities were not sufficient to warrant further changes.

In addition we remove a duplicate implementation of kmap() in DRM.

Testing was done by 0day to cover all the architectures I can't readily
build/test.

I threw some powerpc builds at it and they all passed, so LGTM.

cheers
