crypto: ppc/sha256 - glue
Glue code for crypto infrastructure. Call the assembler code where required. Disable preemption during calculation and enable SPE instructions in the kernel prior to the call. Avoid to disable preemption for too long. Take a little care about small input data. Kick out early for input chunks < 64 bytes and replace memset for context cleanup with simple loop.
