    kernel - Fix bug in resource_list_alloc() for addresses > 4GB
    
    * Fix a bug in resource_list_alloc() that was preventing DFly from
      mapping PCI memory above 4GB.  Basically we had a legacy 'max()'
      function use in there that should have been 'ulmax()'.
    
    * Fixes USB device probe on modern Intel laptops.
    
    * Fixes some VMs which use high addresses to map fake devices.
