Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS update from Ralf Baechle:
"Cleanups and fixes for breakage that occured earlier during this merge
phase. Also a few patches that didn't make the first pull request.
Of those is the Alchemy work that merges code for many of the SOCs and
evaluation boards thus among other code shrinkage, reduces the number
of MIPS defconfigs by 5."
