security FUD? for real? ;) does that mean that you guys would accept a patch that would map the vdso at a fixed address for old times's sake? if not, on what grounds would you refuse it? see, you can't have it both ways.
the fixed address of the vsyscall page *is* a very real security problem, it should have never been accepted as such and it's high time it went away finally in 2011AD.
