msi: fix the ordering of msix irqs
"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.
