SubjectRe: [PATCH] pci: change msi-x vector to 32bit

The justification is questionable. The fact that the irq number
reported for msi-x vectors is only 16bits is a bug. Everywhere else
in the kernel an irq number is stored in a 32bit field.

We also have a few other bits of craziness in the msix interface.
The entry field in msix_entry is unnecessary.

In fact now that we have a linked list of irq entries we stop passing
the structure entirely.
