Modified files:
lib/libc_r/uthread uthread_sem.c
Log:
Condition variable waiters are queued in descending priority order, so
there is no need to wake all waiters to assure that the highest priority
thread is run. As the semaphore code is written, there was no correctness
problem, but the change improves sem_post() performance.
