Hello Linus,
Here is the pull request for dmaengine.
One note though, we have dependency between dmaengine tree and tty tree, as
one series was merged thru Greg's tree. To resolve we had merged
'tty-for-dma' tag from greg's tree into dmaengine next.
This merge will show up conflict in drivers/dma/imx-sdma.c. I am sure you
will manage that :)

async_pq_val: fix DMA memory leak (2016-10-05 06:18:09 +0530)
----------------------------------------------------------------
dmaengine updates for 4.8-rc1
This is bit large pile of code which bring in some nice additions:
- Error reporting: we have added a new mechanism for users of dmaenegine to
register a callback_result which tells them the result of the dma
transaction. Right now only one user ntb is using it.
- As we discussed on KS mailing list and pointed out NO_IRQ has no place in
kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and
ppc users)
- Support for IOMMU slave transfers and it implementation for arm.
- To get better build coverage, enable COMPILE_TEST for bunch of driver,
and fix the warning and sparse complaints on these.
- Apart from above, usual updates spread across drivers.
