Small heads up to potential reviewers:

Daniel found a couple of bugs in patches 6 and 7 where I am not
initializing various gtt information we need in pre-GEN6 case. I've
addressed these and will resend them in the future.

Also, patch 10 needs a better commit message. It was originally two
distinct commits which didn't change behavior, and I picked the wrong
commit message. I shall fix that as well.
