Merge branch 'devel' of master.kernel.org:/home/rmk/linux-2.6-arm
* 'devel' of master.kernel.org:/home/rmk/linux-2.6-arm: (257 commits) [ARM] Update mach-types ARM: 5636/1: Move vendor enum to AMBA include ARM: Fix pfn_valid() for sparse memory [ARM] orion5x: Add LaCie NAS 2Big Network support [ARM] pxa/sharpsl_pm: zaurus c3000 aka spitz: fix resume ARM: 5686/1: at91: Correct AC97 reset line in at91sam9263ek board ARM: 5640/1: This patch modifies the support of AC97 on the at91sam9263 ek board ARM: 5689/1: Update default config of HP Jornada 700-series machines ARM: 5691/1: fix cache aliasing issues between kmap() and kmap_atomic() with highmem ARM: 5688/1: ks8695_serial: disable_irq() lockup ARM: 5687/1: fix an oops with highmem ARM: 5684/1: Add nuc960 platform to w90x900 ARM: 5683/1: Add nuc950 platform to w90x900 ARM: 5682/1: Add cpu.c and dev.c and modify some files of w90p910 platform ARM: 5626/1: add suspend/resume functions to amba-pl011 serial driver ARM: 5625/1: fix hard coded 4K resource size in amba bus detection MMC: MMCI: convert realview MMC to use gpiolib ARM: 5685/1: Make MMCI driver compile without gpiolib ARM: implement highpte ARM: Show FIQ in /proc/interrupts on CONFIG_FIQ ... Fix up trivial conflict in arch/arm/kernel/signal.c. It was due to the TIF_NOTIFY_RESUME addition in commit d0420c83f ("KEYS: Extend TIF_NOTIFY_RESUME to (almost) all architectures") and follow-ups.
