Pull OpenRISC updates from Jonas Bonn:
 "A couple of cleanups for the OpenRISC architecture:

   - Implement IRQ domains
   - Use DMA mapping framework completely and catch up with recent
     changes to dma_map_ops
   - One bug fix to the "or1k_atomic" syscall to not clobber call-saved
     registers
   - OOM killer patches to the pagefault handler ported from the X86
     arch
   - ...and a couple of header file cleanups"
