marcel d50608e9d4 In pci_cfgregread() and pci_cfgregwrite(), multiplex the domain and ... bus number into the bus argument. The bus number occupies the least significant 8 bits. The PCI domain occupies the most significant 24 bits. On the Altix 350, the PCI domain is a required parameter, but changing the prototype of the pci_cfgreg*() functions to include a separate domain argument has wide-spread consequences across the supported architectures. We'd be changing a known interface. Multiplexing is an acceptable kluge to give us what we need with manageable impact. Note that the PCI bus number fits in 8 bits, so the multiplexing of the domain is a backward compatible change.		2013-07-23 03:03:17 +00:00
