The int81 patch would actually be (much!) more important to the average Linux user than getting rid of the vsyscall from static binaries: the vsyscall is the last predictable executable address in PIE daemons with a dangerous SYSENTER instruction in it ... I'd actually consider accelerating it into v2.6.40. Thanks, Ingo
