Attached is an updated patch that addresses Michael Ellerman's comments.
One comment made by Michael has not yet been addressed:
The comment was in regard to the for-loop in
spufs/sched.c:notify_spus_active(). He wondered if the scheduler can
swap a context from one node to another. If so, there's a small window
in this loop (where we switch the lock from one node's active list to
the next) where it may be possible we might miss waking up a context and
send a spurious wakeup to another.
Arnd . . . can you comment on this question?
Thanks.
