  Modified:    sys/pci   pci.c
  Log:
  Remove limit of port I/O addresses to 65K, since PCI specifies 32 bit
  port addresses (even though the PC architecture doesn't support them).
  
  Add code to limit the I/O map size based on the lowest set bit of the
  address. This cures the problem with the BT946C only having a 16 bit
  map register, in voiolation of the PCI specs, without giving up the
  general support of >65K port regions.
