Merge tag 'sh-for-linus' of git://github.com/pmundt/linux-sh

Pull SuperH updates from Paul Mundt:
 - New CPUs: SH7734 (SH-4A), SH7264 and SH7269 (SH-2A)
 - New boards: RSK2+SH7264, RSK2+SH7269
 - Unbreaking kgdb for SMP
 - Consolidation of _32/_64 page fault handling.
 - watchdog and legacy DMA chainsawing, part 1
 - Conversion to evt2irq() hwirq lookup, to support relocation of
   vectored IRQs for irqdomains.
