    Abstract: A system and method for flushing a cache line associated with a linear memory address from all caches in the coherency domain. A cache controller receives a memory address, and determines whether the memory address is stored within the closest cache memory in the coherency domain. If a cache line stores the memory address, it is flushed from the cache. The flush instruction is allocated to a write-combining buffer within the cache controller. The write-combining buffer transmits the information to the bus controller. The bus controller locates instances of the memory address stored within external and intel cache memories within the coherency domain; these instances are flushed. The flush instruction can then be evicted from the write-combining buffer. Control bits may be used to indicate whether a write-combining buffer is allocated to the flush instruction, whether the memory address is stored within the closest cache memory, and whether the flush instruction should be evicted from the write-combining buffer.
