Hi Paolo et al, Based on recently accepted to the mainline pci_enable_msix_exact() function, I am sending a updated version of the patch. Please, let me know if it does not work for you and you need and incremental update from the previous version. Thanks!

As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() and pci_enable_msix_range() interfaces.
