It's up to Lorenzo if he's happy with how pci-hyperv.c ends up looking, I'm not a PCIe expert. My preference would be for a combined series (this and [1] above). Happy to ack the arm64 patches in a combined series (if you are going to post one), the changes would look even simpler. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
