of MSI-X interrupts, and give an example of how to do such a
request.

Matthew Wilcox 1c8d7b0a56 PCI MSI: Add support for multiple MSI
Add the new API pci_enable_msi_block() to allow drivers to
request multiple MSI and reimplement pci_enable_msi in terms of
pci_enable_msi_block.  Ensure that the architecture back ends don't
have to know about multiple MSI.
