hmm.. sparse mem is for the linear map. 

SPE local store used to have special struct pages for it in order to
return things from nopage(). It was dodgy and racy. I killed that
recently, it was causing more problem than it was solving. So it should
be fine now. I'm now using nopfn() and inserting the PTEs directly from
the nopfn() hook.

So Geoff, you can remove the option for now or make it n by default.
