* 'sh/for-2.6.31' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6:
  serial: sh-sci: fix sci interrupt handler
  video: hitfb: Move over to dev_pm_ops.
  video: hitfb: Convert to framebuffer_alloc().
  video: sh_mobile_lcdcfb: Convert to framebuffer_alloc().
  sh: add r8a66597 usb0 host to the se7724 board
  usb: allow sh7724 to enable on-chip r8a66597
  sh-sci: update receive error handling for muxed irqs
  sh: define PERF_COUNTER_INDEX_OFFSET.
