Merge branch 'for-linus' of master.kernel.org:/home/rmk/linux-2.6-arm
* 'for-linus' of master.kernel.org:/home/rmk/linux-2.6-arm: (236 commits) [ARM] 5300/1: fixup spitz reset during boot [ARM] 5295/1: make ZONE_DMA optional [ARM] 5239/1: Palm Zire 72 power management support [ARM] 5298/1: Drop desc_handle_irq() [ARM] 5297/1: [KS8695] Fix two compile-time warnings [ARM] 5296/1: [KS8695] Replace macro's with trailing underscores. [ARM] pxa: allow multi-machine PCMCIA builds [ARM] pxa: add preliminary CPUFREQ support for PXA3xx [ARM] pxa: add missing ACCR bit definitions to pxa3xx-regs.h [ARM] pxa: rename cpu-pxa.c to cpufreq-pxa2xx.c [ARM] pxa/zylonite: add support for USB OHCI [ARM] ohci-pxa27x: use ioremap() and offset for register access [ARM] ohci-pxa27x: introduce pxa27x_clear_otgph() [ARM] ohci-pxa27x: use platform_get_{irq,resource} for the resource [ARM] ohci-pxa27x: move OHCI controller specific registers into the driver [ARM] ohci-pxa27x: introduce flags to avoid direct access to OHCI registers [ARM] pxa: move I2S register and bit definitions into pxa2xx-i2s.c [ARM] pxa: simplify DMA register definitions [ARM] pxa: make additional DCSR bits valid for PXA3xx [ARM] pxa: move i2c register and bit definitions into i2c-pxa.c ... Fixed up conflicts in arch/arm/mach-versatile/core.c sound/soc/pxa/pxa2xx-ac97.c sound/soc/pxa/pxa2xx-i2s.c manually.
