great - i've created tip/x86/dumpstack for this and applied your patches 
there. (that branch embedds tip/x86/core which already embedds 
tip/x86/traps)

it also passed -tip testing still then so the changes are fine. 

Generally if you see your commits show up and stay in tip/master it 
means they get tested with a newly built random kernel about once every 
two minutes or so.

regarding klibc, that's interesting: is that the in-kernel klibc from 
hpa? Which tree are you using to pull that into tip/master? (unless i 
misunderstood what you are doing)
