Hi Greg, this patch needs some prerequisites including "crypto: hash - annotate
algorithms taking optional key".  You got all the prerequisites for 4.14 and
4.15 but not all applied to earlier kernels, so you should hold off on this for
4.9 and earlier for now.  (The prerequisites by themselves shouldn't break
anything though; only this final patch would.)  Thanks,

Eric
