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.
