My apologies.  I should have said I did not recognize anything that
was likely to conflict from what I hear from what I heard.  I did
hear that the pcie port driver was touched to properly handle msi-x and I
foolishly thought that was already merged upstream.  Especially after
I glanced at Jesse's tree and I did not see any recent pci patches.
Which led me to foolishly assume everything had already been merged
into Linus's tree.

Andrew with respect to 2.6.29 my patch while correct and useful has
no immediate utility, as the pciehp driver will crash and burn horribly
if you attempt to hotplug it.  So I should find the other pci port driver
changes and rebase on top of them.  Assuming that patch is scheduled to
merge for 2.6.30.

Eric
