To fix PM_SLEEP=n build itself (with ARM_EXYNOS_CPUIDLE=n) Krzysztof's patch is not enough and patch [1] is also needed (this patch is very simple so I think that it is okay for v3.16). For PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y config more changes are needed and they are contained in patch [2] (please note that this patch depends on patch [3] from Tomasz Figa which was redone recently into [4] so my patch also needs to be refreshed). However if you think that this would result in too much changes for v3.16 kernel we can make ARM_EXYNOS_CPUIDLE select (or depend on) PM_SLEEP for now and fix the issue completely later in v3.17 kernel.
