    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.
