[PATCH v4 00/22] PCI: Cache MSI/MSI-X capability offsets, other cleanup

[Bjorn Helgaas <bhelgaas@google.com>]

This supercedes Gavin's "[PATCH v3 0/5] Retrieve MSI/MSIX cap struct for
once on setup" series from Apr 4, 2013.

It includes Gavin's patches (there were actually only 4 in v3, not 5),
together with more MSI-related cleanup that I did.

There's also a possible bug-fix in xen_initdom_setup_msi_irqs(): previously
it ignored the "Table Offset" bits in the MSI-X capability.  I don't know
enough about Xen to know how it uses struct physdev_map_pirq, but it seems
possible that we should pay attention to those bits.
