Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM: SoC fixes from Olof Johansson:
"I was hoping to be done with fixes for 3.4 but we got two branches
from subarch maintainers the last couple of days. So here is one
last(?) pull request for arm-soc containing 7 patches:
- Five of them are for shmobile dealing with SMP setup and compile
failures
- The remaining two are for regressions on the Samsung platforms"
* tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc:
ARM: EXYNOS: fix ctrlbit for exynos5_clk_pdma1
