[Patch V5 2/7] crypto: AES CBC multi-buffer data structures
This patch introduces the data structures and prototypes of functions
needed for doing AES CBC encryption using multi-buffer. Included are
the structures of the multi-buffer AES CBC job, job scheduler in C and
data structure defines in x86 assembly code.
