Implementation of mutexes

-------------------------



'struct mutex' is the new mutex type, defined in include/linux/mutex.h

and implemented in kernel/mutex.c. It is a counter-based mutex with a

spinlock and a wait-list. The counter has 3 states: 1 for "unlocked",

0 for "locked" and negative numbers (usually -1) for "locked, potential

waiters queued".
