When we add a device with acpiphp, we enumerate all functions in the slot with pci_scan_slot(), regardless of whether they have associated ACPI methods such as _EJ0. When removing the device, we previously removed only the functions with those ACPI methods. This patch makes the remove symmetric with the add: we remove all functions in the slot, whether they have associated ACPI methods or not. With qemu-kvm and SeaBIOS, we can build a multi-function device where only function 0 has _EJ0 and _ADR (see bugzilla below). Removing and re-adding that slot (including all functions of the device) works correctly with Windows guests. This patch makes it also work in Linux guests.

Yinghai Lu authored
Some callers do not supply the bus number aperture, usually because they do not know the end. In this case, we assume the aperture extends from the root bus number to bus 255, scan the bus, and shrink the bus number resource so it ends at the largest bus number we found. This is obviously not correct because the actual end of the aperture may well be larger than the largest bus number we found. But I guess it's all we have for now. Also print out one info about that, so we could find out which path does not have busn_res in resources list.
