Eric W. Biederman	38bc036130	[PATCH] genirq: msi: refactor the msi_ops ... The current msi_ops are short sighted in a number of ways, this patch attempts to fix the glaring deficiences. - Report in msi_ops if a 64bit address is needed in the msi message, so we can fail 32bit only msi structures. - Send and receive a full struct msi_msg in both setup and target. This is a little cleaner and allows for architectures that need to modify the data to retarget the msi interrupt to a different cpu. - In target pass in the full cpu mask instead of just the first cpu in case we can make use of the full cpu mask. - Operate in terms of irqs and not vectors, currently there is still a 1-1 relationship but on architectures other than ia64 I expect this will change.

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.
