I may be wrong here, but I suspect that you're repeating something that I consider to be a mistake that's all over the x86 code. Specifically, you're distinguishing "native" from "compat" instead of "32-bit" from "64-bit". If you did the latter, then you wouldn't need the "native" case to work differently on 32-bit kernels vs 64-bit kernels, I think. Would making this change make your code simpler? The x86 signal code is the worst offender IMO. --Andy
