When attempting to build against 3.17.6, we're seeing redefinition errors on sg_copy calls - at first glance it looks like the API changed and call param order was swapped.

Scatterlist.h of 3.17.6 does not have a prototype named 'sg_copy'. You
probably run a patched kernel. The function in question has been added
to cryptodev-linux after extracting it from a patch sent to LKML (see:
https://lkml.org/lkml/2011/1/17/258). Maybe you have that one applied to
your kernel?
