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.
