Back again, this time based on top of Christophe Leroy's series: http://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=74541
With the magic perk of being the snowpatch maintainer I will try and get the snowpatch results for this series to be applied on top of that series so all the tests aren't failures. There aren't really any major functional changes, just working what I already did into Christophe's framework. The biggest change is that execution prevention is now optional, and all the radix-specific code is now in the radix-specific place where it should be.
