Yinghai Lu 2cfda637e2 EISA/PCI: Fix bus res reference ... Matthew found that 3.8.3 is having problems with an old (ancient) PCI-to-EISA bridge, the Intel 82375. It worked with the 3.2 kernel. He identified the 82375, but doesn't assign the struct resource *res pointer inside the struct eisa_root_device, and panics. pci_eisa_init() was using bus->resource[] directly instead of pci_bus_resource_n(). The bus->resource[] array is a PCI-internal implementation detail, and after commit 45ca9e97 (PCI: add helpers for building PCI bus resource lists) and commit 0efd5aab (PCI: add struct pci_host_bridge_window with CPU/bus address offset), bus->resource[] is not used for PCI root buses any more. The 82375 is a subtractive-decode PCI device, so handle it the same way we handle PCI-PCI bridges in subtractive-decode mode in pci_read_bridge_bases().
