and reasons for why cannot be fixed, thanks.

Use devm_kzalloc instead of kzalloc. With this change, there is no need to
call kfree in error/exit paths.

requires a do-while loop, but there is code that will break if a do-while loop
is used in the macro so we ignore the checkpatch error in this case.

of atleast ~20% seen with encrypting a
buffer size of 8K (1800 ops/sec vs 1400 ops/sec). Improvement will be higher
for much larger blocks though such benchmarking is left as an exercise for the
reader. Also DMA usage is much more simplified and coherent with rest of the
code.

Earlier functions that did a similar sync are replaced by the dma_sync_sg_*
which can operate on entire SG list.

Hi,
I'm having some trouble with using the dma_map/unmap API.
On unmapping a particular page using dma_unmap, it seems that the
PG_dcache_clean flag is set in the page-flags. This is set by the
following statement in __dma_page_dev_to_cpu function in
arch/arm/mm/dma-mapping.c

This should architecturally be the final version of the patch series to
add DMA support for SG lists of any length.
Thanks,

Crypto layer only passes nbytes to encrypt but in omap-aes driver we
need to know number of SG elements to pass to dmaengine slave API.
We add function for the same to scatterwalk library.

Future work in this direction would be to dynamically change between
PIO/DMA mode based on the block size.
