Subject: [GIT PULL] dmaengine/async_tx update for 2.6.35
Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git next
...to receive:
1/ Two new dma drivers ste_dma40 and timb_dma.
2/ A rework of the existing channel-status and channel-control api's to
make them more generic/extensible. Hence the touch-ups to existing dma
drivers and the excursions into drivers/video/, drivers/serial/, and
sound/.
3/ An update to the ioat driver to allow descriptor submission to run
unlocked against descriptor cleanup.
4/ Other cleanups and fixes
There is one more driver to submit, but it depended on the merge of the
ARM tree and will be sent separately. As you can see below there were a
few late patches, but they have seen at least one -next release.
Thanks,
Dan

DMA ENGINE: Do not reset 'private' of channel
The member 'private' of 'struct dma_chan' is meant for passing
data between client and the controller driver.
The DMA client driver may point it to platform specific stuff after
acquiring the channel. So, it is the responsiblity of the same code
to reset it, if it must.
The DMA engine doesn't set it and hence, shouldn't reset it either.
This reseting of private by DMA Engine comes in the way of implementing
default channel settings during DMAC probe. That capability is useful
for not having the clients to always provide platform specific data,
like Rx/Tx FIFO addresses, which usually doesn't change across channel
requests.

ioat3: disable cacheline-unaligned transfers for raid operations
There are cases where cacheline-unaligned raid operations can hang the
dma channel. Simply disable these operations by increasing the
alignment constraints published to async_tx. The raid456 driver always
issues page aligned requests, so the only in-kernel user of the ioatdma
driver that is affected by this change is dmatest.
