Mark Maule fd58e55fcf [PATCH] PCI: msi abstractions and support for altix
Abstract portions of the MSI core for platforms that do not use standard
APIC interrupt controllers.  This is implemented through a new arch-specific
msi setup routine, and a set of msi ops which can be set on a per platform
basis.
