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"
