Merge master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6
* master.kernel.org:/pub/scm/linux/kernel/git/lethal/sh-2.6: sh: SH-4A UBC support sh: interrupt exception handling rework sh: Default enable R7780RP IRQs. sh: Zero-out coherent buffer in consistent_alloc(). sh: Convert IPR-IRQ to IRQ chip. sh: Convert INTC2 IRQ handler to irq_chip. sh: Fix pr_debug statements for sh4 sh: Convert r7780rp IRQ handler to IRQ chip. sh: Updates for IRQ handler changes. sh: Kill off timer_ops get_frequency(). sh: First step at generic timeofday support.
