[Xen-devel] [PATCH 0/3] MSI-X adjustments

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

While putting together a prototype patch to address the security issues
connected to granting guests write access to MSI-X table and pending
bit array I cam across a few other MSI-X related issues. 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
