This patch does: - remove msi/msix_enable/disable macros since they should have been replaced by msi/msix_set_enable() functions - remove unused multi_msi_enable - remove shifts from multi_msi_capable - msix_mask/unmask/pending macros are useless because they are not based on the PCI Local Bus Specification properly. It seems that they were written based on the MSI-X ECN that underwent membership review in September 2002. Remove them and PCI_MSIX_FLAGS_BITMASK. (note: PCI_MSIX_FLAGS_PENDMASK is never defined!)
