// N.B. The lock field of the spin lock queue structure contains the address
// of the associated kernel spin lock, an owner bit, and a lock bit. Bit
// 0 of the spin lock address is the wait bit and bit 1 is the owner bit.
// The use of this field is such that the bits can be set and cleared
// noninterlocked, however, the back pointer must be preserved.
//
// The lock wait bit is set when a processor enqueues itself on the lock
// queue and it is not the only entry in the queue. The processor will
// spin on this bit waiting for the lock to be granted.
//
// The owner bit is set when the processor owns the respective lock.
//
// The next field of the spin lock queue structure is used to line the
// queued lock structures together in fifo order. It also can set set and
// cleared noninterlocked.
