[PATCH] msi: Fix the ordering of msix irqs.

[ebiederm@xmission.com (Eric W. Biederman)]

Yours looks more complete then my test patch so:

From: "Mike Miller (OS Dev)" <mikem@beardog.cca.cpqcorp.net> writes:

Found what seems the problem with our vectors being listed backward. In
drivers/pci/msi.c we should be using list_add_tail rather than list_add to
preserve the ordering across various kernels. Please consider this for
inclusion.
