Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King:
"Another round of ARM fixes. Largest one is the second half of the
PJ4B fix which was pushed in the previous -rc - this one was delayed
because its original caused a build regression while trying to fix a
regression!
As ever, noMMU gets forgotten when fixing problems on MMU, so we have
a noMMU fix for a previous fix included in this set.
A couple of fixes from Lorenzo for problems with the ARM DT CPU code,
and a one liner to remove the buggy 'wait for interrupt' with FA526
cores"
