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

Pull OpenRISC updates from Stafford Horne:
 "Highlights include:

   - optimized memset and memcpy routines, ~20% boot time saving

   - support for cpu idling

   - adding support for l.swa and l.lwa atomic operations (in spec from
     2014)

   - use atomics to implement: bitops, cmpxchg, futex

   - the atomics are in preparation for SMP support"
