I took this in to get it as much coverage in -next as possible. Since we are getting close to the end of the merge window and Stephen Rothwell is on vacation, so -next testing isn't as smooth and predictable as usual. Once Thomas (and others, don't be shy!) has tested it, I'll either add the Tested-by or drop it for a new version. thx, Jason. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
