Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).
To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.
Hope people are OK with tiny include file.
Note, that mm_types.h is still dragged in, but it is a separate story.

wrappers.
Hi,
crypto_free_hash() and crypto_free_ablkcipher() are just wrappers around
crypto_free_tfm() which is itself just a wrapper around
crypto_destroy_tfm().
Passing crypto_destroy_tfm() a NULL pointer is valid, so there's no reason
to check for NULL first.
Removing the unneeded conditionals (which is what the patch does) brings
us the benefit of having to execute a few fewer test/branch instructions
and also reduces object code size slightly:

POHMELFS is able to encrypt the whole network channel or
attach the strong checksum to own packets to catch faulty media.
This patch implements crypto initialization, its autoconfiguration
and sync with the server.
