I think both Agustin's patch set and my mbigen one are in good shape now if I didn't miss something, Rafael and Lorenzo already acked Agustin's patch [1-2/3], I provided my review and test tags on them. And Lorenzo said about the mbigen patches: "I think this patch (and the FW that goes with it) is wrong, but the rest of the series, in particular the IORT bits, are ok with me." and I fixed the wrong patch and updated the _PRS to _CRS as Lorenzo suggested in v8. So, can I kindly ask that those patches (Agustin's patch set and my mbigen one) be merged to 4.11 please? It's really important for Hisilicon (Hip06/Hip07) SoCs which native NIC [1], SAS [2], USB and even the console on Hip07-D05 drivers depend on those patches, and those platform are completely dead without them if PCI is not enabled...
