Merge tag 'samsung-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes
Merge "Samsung fixes-2 for v3.16" from Kukjin Kim: - fix the check for SMP configuration with using CONFIG_SMP not just SMP - fix the number of pwm-cells for exynos4 pwm - fix ftrace for exynos_mct - register exynos_mct for stable udely - fix secondary boot addr for secure mode for exynos SoCs * tag 'samsung-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: EXYNOS: Update secondary boot addr for secure mode clocksource: exynos_mct: Register the timer for stable udelay clocksource: exynos_mct: Fix ftrace ARM: dts: fix pwm-cells in pwm node for exynos4 ARM: EXYNOS: Fix the check for non-smp configuration Signed-off-by: Olof Johansson <olof@lixom.net>
