Resending. Incorporated a minor fix pointed out by Isaku Yamahata.
Here is the port of MSI-X support patches to upstream qemu.
Please comment or commit.
This patchset adds generic support for MSI-X, adds implementation in
APIC, and uses MSI-X in virtio-net. At Paul's suggestion, I use stl_phy
to decouple APIC and MSI-X implementation.
This uses the mask table patch that I posted previously, and which is
now included in the series.
