Very strange. Looks like there has been some rebase weirdness which have 
applied the patch on the wrong block at some point on my side, probably 
due to the fact that both blocks have the two previous and following 
lines identical.

I've now rebased my serie on cryptodev/master and have the same 
behaviour as you. I'll resend the series without this patch.
