Merge master.kernel.org:/home/rmk/linux-2.6-arm
* master.kernel.org:/home/rmk/linux-2.6-arm: [ARM] AACI: timeout will reach -1 [ARM] Storage class should be before const qualifier [ARM] pxa: stop and disable IRQ for each DMA channels at startup [ARM] pxa: make more SSCR0 bit definitions visible on multiple processors [ARM] pxa: fix missing of __REG() definition for ac97 registers access [ARM] pxa: fix NAND and MMC clock initialization for pxa3xx
