13	   This allows device drivers to enable MSI (Message Signaled
14	   Interrupts).  Message Signaled Interrupts enable a device to
15	   generate an interrupt using an inbound Memory Write on its
16	   PCI bus instead of asserting a device IRQ pin.
17
18	   Use of PCI MSI interrupts can be disabled at kernel boot time
19	   by using the 'pci=nomsi' option.  This disables MSI for the
20	   entire system.

22	   If you don't know what to do here, say N.

26	depends on PCI && DEBUG_KERNEL
27	help
28	  Say Y here if you want the PCI core to produce a bunch of debug
29	  messages to the system log.  Select this if you are having a
30	  problem with PCI support and want to see more of what is going on.
31
32	  When in doubt, say N.

38	help
39	   This allows native hypertransport devices to use interrupts.
