2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Tejun Heo <[email protected]> commit 77c5fd19075d299fe820bb59bb21b0b113676e20 upstream. pata_mpc52xx supports BMDMA but inherits ata_sff_port_ops which triggers BUG_ON() when a DMA command is issued. Fix it.
