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.

2013-06-19ARM: EXYNOS: Select PINCTRL_EXYNOS for exynos4/5 at chip levelDoug Anderson
Previously if you had MACH_EXYNOS5_DT but not MACH_EXYNOS4_DT you'd be missing the pincontrol definitions. Move PINCTRL selects to the arch level since we should be enabling the code for all exynos variants. Update the PINCTRL descriptions to indicate that PINCTRL_EXYNOS is not for exynos5440. Also add basic dependencies for the PINCTRL_EXYNOS kernel config.

2013-06-18parisc: fix kernel BUG at arch/parisc/include/asm/mmzone.h:50 (part 2)Helge Deller
Make sure that we really return -1 (instead of 0x00ff) as node id for page frame numbers which are not physically available. This finally fixes the kernel panic when running cat /proc/kpageflags /proc/kpagecount. Theoretically this patch now limits the number of physical memory ranges to 127 instead of 254, but currently we have MAX_PHYSMEM_RANGES hardcoded to 8 which is sufficient for all existing parisc machines.
