Merge your branch with the android-common 3.18 branch, and try to run
that.  Note, there will be some conflicts, and I think there's a random
qualcomm branch somewhere on code aurora somewhere that has those
problems resolved if you have problems with them.

good luck, it's possible to do (I have a phone running the latest 3.18
release on it with a qcom chipset), but it all depends on exactly what
device you have as to how easy/hard it is going to be!
