kernel - Increase x86_64 & vkernel kvm, adjust vm_page_array mapping
* Change the vm_page_array and dmesg space to not use the DMAP area.
The space could not be accessed by userland kvm utilities due
to that issue.
TODO - reoptimize to use 2M super-pages.
* Auto-size NKPT to accomodate the above changes as vm_page_array[]
is now mapped into the kernel page tables.
* Increase NKPDPE to 128 PDPs to accomodate machines with large
amounts of ram. This increases the kernel KVA space to 128G.
