[POWERPC] spufs: runqueue simplification
This is the biggest patch in this series, and it reworks the guts of
the spu scheduler runqueue mechanism:
- instead of embedding a waitqueue in the runqueue there is now a
simple doubly-linked list, the actual wakeups happen by reusing
the stop_wq in the spu context (maybe we should rename it one day)
- spu_free and spu_prio_wakeup are merged into a single spu_reschedule
function
- various functionality is split out into small helpers, and kerneldoc
comments are added in various places to document what's going on.
- spu_activate is rewritten into a tight loop by removing test for
various impossible conditions and using the infrastructure in this
patch.
