* Simplification, queue pointers don't wrap (except at INT_MAX, but the ↵Jens Arnold2007-04-14

* Fix a hole in the scheduler where collisions between waking blocked threads ↵Michael Sevakis2007-03-26
| | | | | | in mutexes with interrupts waking blocked threads in message queues can occur. Queue posts will put the threads on a separate list that is then added to the running list with IRQs disabled on the next task switch or CPU wakeup. Basically no overhead for other operations. Seems a likely cause of my occasional observation of the backlight fade causing playback threads to stop running and a recently reported blocking violation upon USB plugging. Time will tell but banging the backlight on and off frequently hasn't hiccuped again for me on H120. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12915 a1c6a512-1295-4272-9138-f99709370657

A couple spots needed interrupt stopage where there could be confict if an IRQ post wakes a waiting thread because the queue is overflowing. There does appear to be an issue with wakeup_thread, interrupts and running list modification in general. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12895 a1c6a512-1295-4272-9138-f99709370657
