The slab.h header is required to use the kmalloc() family of functions.
Due to recent kernel changes, this header must be directly included by
code that calls into the memory allocator.
Without this patch, any code which includes this header fails to build.

Use the DMA_SLAVE capability of the DMAEngine API to copy/from a
scatterlist into an arbitrary list of hardware address/length pairs.
This allows a single DMA transaction to copy data from several different
devices into a scatterlist at the same time.
This also adds support to enable some controller-specific features such as
external start and external pause for a DMA transaction.
