Message:

Use the semaphore interface instead of waitq in some places

Since we already have an underused semaphore API in the kernel,
it would be worthwhile to use it in places where the baseline
semaphore semantics are needed. It makes the function of the
calls obvious even to people unfamiliar with the details of
waitq API.
