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.
