Jeenu Viswambharan 82a0aca053 Rework bakery lock with WFE/SEV sequence ... Current implementation of Bakery Lock does tight-loop waiting upon lock contention. This commit reworks the implementation to use WFE instruction for waiting, and SEV to signal lock availability. It also adds the rationale for choosing Bakery Locks instead of exclusion primitives, and more comments for the lock algorithm.
