Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "Here's my usual Sunday push, just for one revert which PeterZ hollered about after last weeks push. Other than that, all seems strangely quiet as far as fixes go in non-platform ARM land at the moment." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: Revert "ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus"
