Mark, thanks for doing this work. The better abstracted out the so-called generic MSI support code is, the better. Several platforms will benefit from this, such as PPC and Sparc64, both of which cannot take advantage of MSI support in their PCI controllers because of how x86 centric the current MSI support layer is. Thanks again. - : send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
