Subject: msi: fix the ordering of msix irqs
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>

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.
