Log:
  Minimal change to build linuxkpi on architectures with physical addresses larger
  than virtual
  
  Summary:
  Some architectures have physical/bus addresses that are much larger
  than virtual addresses.  This change just quiets a warning, as DMAP is not used
  on those architectures, and on 64-bit platforms uintptr_t is the same size as
  vm_paddr_t and void *.
