Log Message:
New kernel mutex implementation, modeled after those found in Solaris
and described in:

	Solaris Internals: Core Kernel Architecture, Jim Mauro and
	    Richard McDougall, section 3.5.

Both adaptive (spin/sleep) and spin (spin + block interrupts) mutexes
are implemented.  See <sys/mutex.h> for the support that machine-dependent
code must supply.
