 * async_xor_val - attempt a xor parity check with a dma engine.

 * @dest: destination page used if the xor is performed synchronously

 * @src_list: array of source pages

 * @offset: offset in pages to start transaction

 * @src_cnt: number of source pages

 * @len: length in bytes

 * @result: 0 if sum == 0 else non-zero

 * @submit: submission / completion modifiers

 *

 * honored flags: ASYNC_TX_ACK

 *

 * src_list note: if the dest is also a source it must be at index zero.

 * The contents of this array will be overwritten if a scribble region

 * is not specified.
