to receive:

Dan Williams (5):
      async_tx: fix compile breakage, mark do_async_xor __always_inline
      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

Denis Cheng (2):
      async_tx: use LIST_HEAD instead of LIST_HEAD_INIT

The series is a general cleanup to the async_tx-api for 2.6.25.  The
most significant change 'async_tx: kill tx_set_src and tx_set_dest
methods' removes the need to perform extra indirect calls when preparing
a descriptor.  However, in order to keep the same stack footprint,
async_xor now polls for engine resources rather than simply punting to
cpu-xor.

The code was sent out for review in December [1], and has received an
Acked-by from Shannon@...el for the parts that touch ioat_dma.
Haavard@...el has supplied a Reviewed-by for the pieces he felt
comfortable judging the correctness.

Regards,
Dan
