Hi, Geert emailed me this afternoon concerned about blake2s codesize on m68k and other small systems. We identified two extremely effective ways of chopping down the size. One of them moves some wireguard-specific things into wireguard proper. The other one adds a slower codepath for CONFIG_CC_OPTIMIZE_FOR_SIZE configurations. I really don't like that slower codepath, but since it is configuration gated, at least it stays out of the way except for people who know they need a tiny kernel image Thanks, Jason Jason A.
