I think this is just a false alarm.  sysenter_setup always prints this, 
but if compat mode isn't enabled this is just the address the compat 
vdso would be at if it were mapped.  You can confirm this by doing "cat 
/proc/self/maps" and making sure that there's nothing mapped at 
ffffe000.  And then cross confirm with "sysctl -w vm.vdso_enabled=2; cat 
/proc/self/maps" to make sure it appears.
