Unfortunately, skas and PaX are pretty tricky to merge. I also have doubts
about the rmap VM integrating well with UML, but I could be wrong there.

Did you consider dropping the rmap VM? It must make integrating most patches
a lot more difficult than necessary. I've been using non-wolk, non-rmap
kernels for a while now, and couldn't see substantially worse performance
even under heavy memory load.

Are the benefits really worth the cost?
