Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"First ARM push of this merge window, post me coming back from holiday.
This is what has been in linux-next for the last few weeks. Not much
to say which isn't described by the commit summaries."
