I had gone through and tested with each patch applied individually when I was performance testing them, and I am fairly certain there wasn't a bug introduced between any two patches. The issue that I recall Michal had was the fact that I was essentially embedding the setting of the reserved page under several layers of function calls, which would make it harder to remove. I started that work at about patch 5 which is why I figured I would resend the first 4, and hold off on 5-7 until I can get the reserved bit removal for hotplug done. I can probably have the patches ready to go in a couple days. I'll send updates once linux-next and mmotm with the patches dropped have been posted. Thanks. - Alex
