pc64: move VMAP into its own PDP (for vmware)
modifying the kernel pdp (CPU0PDP) hangs vmware. so
we initialize the pdp with KZERO and KZERO+1GB map
in l.s and never change it. (except when removing
the zero double map which seems to work).
VMAP has its own pdp now allowing to map 512GB of
physical address space. this simplifies the code
a bit and gives nice virtual addresses.
