Sure, later today (as of now I only have ssh access to the machine).

I've never done a git bisection before (and I don't have the toolchain
installed, this is - was, now that all hell broke loose with Meltdown and
friends - a computer with very limited use), but I wager it's going to be
painful to do kernel compiles on an Atom 330… I may try to do so on the
weekend, but no promises. :(
Actually, I just reported this now because I was expecting this error to be
found by someone else, being so obvious. :P It's happening since 4.15-rc1 (the
first release I tested after the merge window).
