	Some systems (such as the ASB2305) have PCI onboard. If you have one
	of these boards and you wish to use the PCI facilities, say Y here.

	The PCI-HOWTO, available from
	<http://www.tldp.org/docs.html#howto>, contains valuable
	information about which PCI hardware does work under Linux and which
	doesn't.

	local_irq_disable() doesn't actually disable maskable interrupts -
	what it does is restrict the levels of interrupt which are permitted
	(a lower level indicates a higher priority) by lowering the value in
	EPSW.IM from 7. Any interrupt is permitted for which the level is
	lower than EPSW.IM.

	Certain interrupts, such as GDBSTUB and virtual MN10300 on-chip
	serial DMA interrupts are allowed to interrupt normal disabled
	sections.
