Prompted by Yuri's RAID6 acceleration implementation [1], and Haavard's DMA-slave interface [2], this series cleans up the async_tx api and prepares it for these new features. The most invasive change is the removal of the tx_set_src and tx_set_dest methods in patch 2/4, drivers now receive all necessary operation information at 'prep' time.
Still on the to do list: * Pull the mpc85xx driver from -mm and integrate these api changes * Apply Haavard's dma-test-client [3]. Look into extending it for other operations and async_tx channel switching testing * Teach async_tx about drivers that do not support channel switching
This series is based on 2.6.24-rc6.
Dan Williams (4): async_tx: kill ASYNC_TX_ASSUME_COHERENT async_tx: kill tx_set_src and tx_set_dest methods async_tx: replace 'int_en' with operation preparation flags async_tx: allow architecture specific async_tx_find_channel implementations
