will:         down_read(&pci_bus_sem);
also enable interrupts?
Since that is called:
init/main.c         start_kernel
kernel/params.c      parse_args("Booting kernel"
kernel/params.c       parse_one
drivers/ide/ide.c      ide_setup
drivers/ide/ide.c       init_ide_data
drivers/ide/ide.c        init_hwif_default
include/asm-i386/ide.h    ide_default_io_base(index)
drivers/pci/search.c       pci_find_device
drivers/pci/search.c        pci_find_subsys
                             down_read(&pci_bus_sem);
