[PATCH] increase PCIBIOS_MIN_IO on x86 There is a number of x86 laptops that have some non-PCI IO ports in the 0x1000-0x1fff range, and it's quite hard to control the correct order of resource allocation between PCI and other subsystems controlling these ports. Especially with modular kernel. So just increase PCIBIOS_MIN_IO to 0x4000 to prevent any new PCI resource allocations in the problematic range (this limitation must apply _only_ to the root bus resources - see Linus' change in pci_bus_alloc_resource). As PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO are the same now on i386 and x86-64, we can remove the latter.
