[NTOS]: He's climbing in yo PFN database, he snatching yo pages up, tryin to page em so y'all need to hide your pool hide your cache, and hide your working set cuz they grabbin' all the pages out there. We gonna page you, we gonna page you, so you can run and fault on that, run and fault on that, home boy, homeboy, home homeboy.

Enable ARM3 Paged Pool and remove all related deprecated code. Install tested on several VMs, it might cause new regressions. Let's fix them before 0.3.13 instead of reverting.
