2013-06-19ARM: dts: fork out common EXYNOS5 nodesChander Kashyap
In preparation of adding support for EXYNOS5420, which has many peripherals similar to EXYNOS5250, a new common EXYNOS5 device tree source file is created out of the exising EXYNOS5250 device tree source file. Only the common nodes required for basic boot up on EXYNOS5420 based boards are moved into this new file and the rest of the common nodes would be moved subsequently. EXYNOS5440 SoC is quite different from EXYNOS5250 and EXYNOS5420. Hence it is not possible to reuse "exynos5.dtsi" for EXYNOS5440.

This finally fixes the kernel panic when running cat /proc/kpageflags /proc/kpagecount.

2013-06-18cgroup: clean up cgroup_serial_nr_cursorTejun Heo
cgroup_serial_nr_cursor was created atomic64_t because I thought it was never gonna used for anything other than assigning unique numbers to cgroups and didn't want to worry about synchronization; however, now we're using it as an event-stamp to distinguish cgroups created before and after certain point which assumes that it's protected by cgroup_mutex. Let's make it clear by making it a u64. Also, rename it to cgroup_serial_nr_next and make it point to the next nr to allocate so that where it's pointing to is clear and more conventional.
