  vfio-pci: Release all MSI-X vectors when disabled (2013-12-06 11:16:40 -0700)

----------------------------------------------------------------
vfio-pci updates include:
 - Update linux-headers to include KVM-VFIO device support
 - Enable QEMU support for KVM-VFIO device
 - Additional Nvidia x-vga quirk to ACK MSI interrupts
 - Debug options to disable MSI/X KVM acceleration
 - Fix to cleanup MSI-X vectors on shutdown and avoid IRQ route leaks

The KVM-VFIO device support enables KVM to manage how it handles
coherency instructions in the presence of non-coherent I/O.  Dave
Airlie had noted that the Nvidia MSI ACK support here may just be
scratching the surface, but it's better than what we have now and
it's only enabled via the x-vga option, so I'm willing to add since
it does enable some users.
