Your or I missed a bug fix/enhancement in there somewhere.
Basically my very early setup of the fixmap failed. Now. I thought I had that covered by preallocated the pud and the pmd entries. So the only thing missing was the pte entries.
If that is not a big enough hint I will look into it in a bit...
I'm starting to become a big fan of constant initializers. So our core subsystems don't need initialization code to be useful. All of these early things are just a pain.
