Cap the initial PV and PTE table preallocations.  Otherwise we explode
on the Itanium2 system I have when we use up *all* of the initial 256MB
direct mapped region before we are ready to dynamically expand it.

The machine that I have has 4 cpus and a very big hole in the middle.
This makes the bogus '(last_address - first_address) / PAGE_SIZE'
calculations especially dangerous and caused many millions of initial
PV/PTE's to be preallocated.
