This doesn't quite work as-is, though. For example, at least the PK bit is independent of the other bits and would be interesting in the human-legible version, but doesn't show up there at all. That said, I think the end result might be more legible than the previous version, so this approach may well be good, it just needs at least that "permissions violation" part to be extended with whether it was PK or not. Also, shouldn't we show the SGX bit too as some kind of "during SGX" extension on the "in user/kernel space" part? Linus
