* Improve acpi interrupt fixup a bit * Source is an array, don't compare it to NULL, instead look for an empty string to denote a link-device-less entry. * For root PCI busses, try to use the _BBN method to get numbering right. * Add acpi_md_callback() function for MD handling after the init, but before * at acpi probing.
