FYI, this change is not exactly correct...
The patch should also remove another "ifdef TIF_NOTIFY_RESUME" above,
see the original patch:
http://marc.info/?l=linux-kernel&m=133487746527839
This part was lost because the patch was routed via Al Viro's tree,
and that ifdef was already killed by 1227dd77
However, I guess we do not care, fedora kernel doesn't run on
!TIF_NOTIFY_RESUME machines.
So I think the patch is fine for F16/F17
