Provided you also include the minor fix [2] to make perf tools work. :-) Additionally it would make sense to include the patches from Josh that add SFrame information to the vDSO on x86 [3].

The prctl() patch is added for debugging > purposes only. Does PR_SET_VMA [4] create a precedent case for the SFrame prctls?
