[-- Attachment #1 --] I'm refering to the following two lines in sys/i386/i386/trap.c /* kludge to pass faulting virtual address to sendsig */ frame->tf_err = eva; Isn't there some other way to do this? Wouldn't the address still be available in %cr2 inside sendsig? Or could there have been other page faults by then? The reason I'm asking this is that Wine wants to know the error code in case of a page fault (the No eXec bit (AMD) and the read/write bit specifically).
