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.
