1. A method, on a mirrored lock cache, for propagating data to other mirrored lock caches, the method comprising: coupling a first mirrored lock cache associated with a first processing node to a bus communicatively coupled to at least a second mirrored lock cache associated with a second processing node in a multi-processing system, wherein the first mirrored lock cache and the at least second mirrored lock cache are communicatively coupled to a non-cache memory within the multi-processing system, wherein the first mirrored lock cache and the at least second mirrored lock cache are physical memories that are separate and distinct from each other and from the non-cache memory, wherein a width of the first mirrored lock cache and the at least second mirrored lock cache is smaller than a non-mirrored lock cache within the multi-processing system, wherein the first mirrored lock cache and the at least second mirrored lock cache each comprise less cache entries than the non-mirrored lock cache, and wherein a number of the cache entries in the first mirrored lock cache and the at least second mirrored lock cache is a function of a number of processors in the multi-processing system; analyzing a page table in a memory management unit comprising mapping bits associated with the first mirrored lock cache to identify a particular set of entries that are to be kept within the first mirrored lock cache; preventing the data residing in the first mirrored lock cache and the at least second mirrored lock cache from being mapped into the non-mirrored lock cache; setting an availability flag for indicating the availability of a lock residing in the first mirrored lock cache that is associated with the availability flag; receiving a request from a processor to acquire a lock residing in the first mirrored lock cache, the request including at least a time stamp and a processor ID associated with the processor; determining whether the time stamp precedes other time stamps associated with other requests from other processors; writing the processor ID into the lock in response to the time stamp preceding the other time stamps associated with the other requests from the other processors; granting the processor access to the lock only if the processor ID associated with the processor matches the processor ID written into the lock; atomically updating by the first mirrored lock cache, in response to the processor being granted access to the lock, a lock word associated with the lock; automatically mirroring, by the first mirrored lock cache, the lock word to the at least second mirrored lock cache independent of a processor of the multi-processing system so that the lock word which has been updated is reflected within the at least second mirrored lock cache; receiving, by the first mirrored lock cache, data from a processing node; mirroring, by the first mirrored lock cache, the data automatically, in response to receiving the data, to the at least second mirrored lock cache independent of a processor of the multi-processing system so that identical data is available locally at the at least second mirrored lock cache for use by the second processing node; receiving a new allocation request associated with at least the first mirrored lock cache; determining, in response to receiving the new allocation request, that the first mirrored lock cache comprises insufficient space for a new allocation of data associated with the new allocation request; moving at least one lock currently residing within the first mirrored lock cache to the non-mirrored lock cache; and granting the new allocation request in response to moving the at least one lock to the non- mirrored lock cache.
