If you're wondering why a register contains 0xfaf0f1fe (or 0xFAF0F1FE) or 0xFEF1F0FA on big-endian machines, and you think "I can guess that's a marker, and I'm sure I've seen that somewhere" but can't find it with grep, you'll find it in the place you first thought of: /sys/src/libc/port/pool.c where it appears as separate bytes as the "datamagic" data sequence 0xFE, 0xF1, 0xF0, 0xFA (which you might also see written that way in a memory dump).
