Hi,
I'm facing a NULL pointer dereference in omap_hsmmc_start_command() on
an AM33xx board running 3.11-rc1 (DMA enabled).
A quick debug session showed that DMA engine timing leads to a very
reproducable race condition. In

The EDMA DMAC has a hardware limitation that prevents supporting
scatter gather lists with any number of segments. The DMA Engine
API reports the maximum number of segments a channel can support
via the optional dma_get_slave_sg_limits() API. If the max_nr_segs

Add a dmaengine API to retrieve slave SG transfer limits.
The API is optionally implemented by dmaengine drivers and when
unimplemented will return a NULL pointer. A client driver using
this API provides the required dma channel, address width, and
burst size of
