Hey, those breakages are in the kvm tree not the arm64 tree! I'd really rather wait on these as I don't see the rush to get them in for 3.17 and it's not beyond the realms of possibility that they could cause problems for a particular version of GCC (at the very least, I'd need to re-run all the testing I've been doing).
