You can't revert that without reverting my whole series.

Adding a #include ../mm/mmu_decl.h to the kvm code should fix it for
now.

I need to talk to hollis about the right way to do that stuff in
the long run but it might be it... those _tlbil things are low level
stuff that aren't supposed to be used by the outside world which is
why I moved the declarations there, but KVM is also low level :-)

Cheers,
