We can take it through -tip and I prefer to do so as there are other
changes in the page table code lurking.

We probably need to split it apart:

   - Apply the mm core only parts to a branch which can be pulled into
     Andrews mm-tree

   - Base the x86 changes on top of it

So both worlds can work on top of the mm core parts (almost
independently). From what I have seen so far, it's more likely that we get
delta changes/fixes on the x86 side than on the mm core side. And if we get
changes on the mm core side, we can deal with that via the seperate mm core
branch.

Andrew, does that work for you?

Thanks,
