2019-05-19test/test_sref_noref: fix naming, reduce number of loopsRichard Braun
2019-05-19kern/sref: reworkRichard Braun
Remove CPU registration, optimize manager weak-ups, replace the global review queue with local review queues. CPU registration and the global review queue were motivated by low power consumption, but considering how the kernel is evolving, this was likely overengineering.

2019-01-10kern/semaphore: reworkRichard Braun
The previous implementation, which uses a combination of fast and slow paths around accessing an atomic integer, suffers from a bug triggered when two or more posts are performed back-to-back, without a waiter decrementing the semaphore value in between. The first post would be the only one signalling a waiter. In addition, having a fast path that expects the absence of waiters probably doesn't make sense, as semaphores are expected to be used for signalling threads. As a result, it was decided to remove the fast path altogether, and protect the semaphore value with sleep queues. Finally, as part of the rework, semaphores now have a user-defined maximum value, in order to make the implementation of, e.g. wrappers for binary semaphores, convenient. Thanks to Simon Venken for reporting the bug.
