Yep.  And I'm not too keen on that name; one could imagine other uses
for those hooks, even if they're being used for x86 paravirtualization
in this instance.

I suppose this is just me being lazy ... I'm currently doing a bit of a
rewrite in asm-parisc/mmu_context.h and I didn't want a massive merge
conflict.
  

Well, I'm happy to create asm-generic/mm_hooks.h or something, and
reduce all the changes to asm-*/mmu_context.h to a one-liner.
