The kernel stack offset should be aligned to 16 bytes. Previously it was aligned to 8 bytes. It's unclear if this was the cause of any issues, but it is best practice to keep things aligned to 16 bytes. As part of this, key the atomic instructions off of the CPP macro presence of atomic instructions. Signed-off-by: Sean Cross <sean@xobs.io>
