- Fixed a wrong instruction in mutex.S user library - Added support for blocking lock/unlock - Divided waiting into wait_on_prepare and wait_on_prepared_wait so that mutex_control lock is released after getting in the waitqueue. - Declaring waitqueue on the stack should be done outside wait_on_prepare Issues: - Tests can be simplified for atomic data access instead of producer/consumer. - kmalloc variable sized memory caches are not freed properly. Currently only the last slot can be freed, occupied correctly. it should be done in any slot, i.e. 1, 2, 3, 4 instead of just 5. - Need to add a mutex to kmalloc.
