2011-11-11ARM: smp: fix clipping of number of CPUsRussell King
commit a06f916b7a9b57447ceb875eb0a89f1a66b31bca upstream. Rather than clipping the number of CPUs using the compile-time NR_CPUS constant, use the runtime nr_cpu_ids value instead. This allows the nr_cpus command line option to work as expected.

2011-09-27ARM: EXYNOS4: Rename sclk_cam clocks for FIMC driverSylwester Nawrocki
The sclk_cam clocks are now controlled by the top level FIMC media device driver bound to "s5p-fimc-md" platform device. Rename sclk_cam clocks so they accessible by the corresponding driver.

2011-09-15ARM: EXYNOS4: Fix routing timer interrupt to offline CPUKukjin Kim
The commit 5dfc54e087c15f823ee9b6541d2f0f314e69cbed ("ARM: GIC: avoid routing interrupts to offline CPUs") prevents routing interrupts to offline CPUs. But in case of timer on EXYNOS4, the irq_set_affinity() method is called in percpu_timer_setup() before CPU1 becomes online. So this patch fixes routing timer interrupt to offline CPU.
