Subject: What's in async_tx.git/next for 2.6.32?

Provided Neil and Peter provide their acks for the raid6 acceleration 
work, here is what is pending in async_tx.git/next for 2.6.32:

1/ Ira's DMA_SLAVE support for the fsldma driver that just missed the 
2.6.31 window
2/ raid6 extensions to the async_tx api
3/ percpu conversion of the md-raid456 stripe processing resources 
(address buffers / raid6-spare-page)
4/ conversion of md-raid6 to the asynchronous raid6 api
5/ experimental support for offloading stripe processing to the async 
thread pool (multicore raid)
6/ raid offload support for the ioatdma driver (v3.2 of Intel(R) 
QuickData Technology)
