Well, this #include is the reason why I moved mmu.c to mmu/spp.c.  It
shouldn't be hard to create a mmu_internal.h header for things that have
to be shared between mmu.c and spp.c, but I'm okay with having the
#include "spp.c" for now and cleaning it up later.  The spp.c file,
albeit ugly, provides hints as to what to put in that header; without it
it's a pointless exercise.

Note that there isn't anything really VMX specific even in the few vmx_*
functions of spp.c.  My suggestion is just to rename them to kvm_mmu_*.
