[v2,6/6] cpu/idle.c: move to sched/idle.c

Commit Message

Nicolas Pitre Jan. 29, 2014, 5:45 p.m. UTC

Integration of cpuidle with the scheduler requires that the idle loop be
closely integrated with the scheduler proper. Moving cpu/idle.c into the
sched directory will allow for a smoother integration, and eliminate a
subdirectory which contained only one source file.
