Modified files:
sys/kern kern_intr.c
sys/sys interrupt.h
Log:
- Remove the global ithread_list_lock spin lock in favor of per-ithread
sleep locks.
- Delay returning from ithread_remove_handler() until we are certain that
the interrupt handler being removed has in fact been removed from the
ithread.
- XXX: There is still a problem in that nothing protects the kernel from
adding a new handler while the ithread is running, though with our
current architectures this is not a problem.
