	This patch removes the write-queue entry tracking previously used for uncacheable writes. The write-queue entry is now deallocated as soon as the packet is sent. As a result we also forego the stats for uncacheable writes. Additionally, there is no longer a need to attach the write-queue entry to the packet.
2016-03-17	mem: Create a separate class for the cache write buffer	Andreas Hansson
	This patch breaks out the cache write buffer into a separate class, without affecting any stats. The goal of the patch is to avoid encumbering the much-simpler write queue with the complex MSHR handling. In a follow on patch this simplification allows us to implement write combining. The WriteQueue gets its own class, but shares a common ancestor, the generic Queue, with the MSHRQueue.
