I've sent that series refreshed with Jann's emulator now[1]. (Which I
see you've replied to as well, but I figured I'd just link these threads
for any future archaeology. ;)

If you could add ALU|AND, that would get us complete coverage for
libseccomp and Chrome. I don't want the emulator to get any more complex
than that, as I view it as fairly high risk part. As you can see, I
tried really hard to _not_ use an emulator in the RFC. ;)
