Since I don't have any MSI-X capable devices (or drivers thereof), I can't really test those changes, so review of the changes before applying is required. 1) prevent simultaneous use of MSI and MSI-X 2) allow the MSI-X table to reside beyond 4G even on 32-bit systems 3) consolidate MSI-X related definitions Signed-off-by: Jan Beulich
