This effectively undoes the PCI resource allocation changes done in commit b408cbc704352eccee301e1103b23203ba1c3a0e, but leaves the cleanups of that commit in place. We're going back to marking the resources reported by e820 busy _before_ doing PCI probing, so that any PCI resource that clashes with the BIOS- reported memory map will be reloacted to a non-clashing area. The reason? Larry Finger reports that his laptop has the cardbus controller set up by the BIOS so that it conflicts with the e820 memory map, and needs to be relocated. See http://bugzilla.kernel.org/show_bug.cgi?id=6337 for more details. We'll have to work out how to handle the fbcon problem that caused that commit in the first place in some other way.
