Forgot to mention yesterday: the NEWS file will need to
contain an entry for this. You can add a single entry that
covers both this series and the previous PCIe-related
series, or just document the previous one if this one
somehow doesn't make it into the release.

[libvirt] [PATCH v2 0/4] qemu: assign vfio devices to PCIe addresses when appropriate

[Laine Stump]

Patches 1 and 4 were originally added to the end of the "more PCIe
less legacy PCI" patchset in its final incarnation, but all the other
patches were ACKed and pushed, while this needed a bit more work,
resulting in this "faux V2" - although it's the 2nd time I've posted
these patches, their "V1" was really inside the "V11666" of a larger
series.

In order to implement Alex's suggestion of checking the length of a
PCI device's config file to determine if it's an Express device, I
first made a utility function to return the length of a file, and then
another to return the name of the config file of a virPCIDevice -
those are the new patches 2 and 3.

I'm open to suggestions about additional checks to put in
virFileLength(), as long as they don't involve opening the file. For
now I've kept it as simple as possible. (Just keep in mind that I'll be away 
from my keyboard from Wednesday through Sunday this week).
