This patch moves the bakery locks out of coherent memory to normal memory. This implies that the lock information needs to be placed on a separate cache line for each cpu. Hence the bakery_lock_info_t structure is allocated in the per-cpu data so as to minimize memory wastage. A similar platform per-cpu data is introduced for the platform locks. As a result of the above changes, the bakery lock api is completely changed. Earlier, a reference to the lock structure was passed to the lock implementation. Now a unique-id (essentially an index into the per-cpu data array) and an offset into the per-cpu data for bakery_info_t needs to be passed to the lock implementation.
