BTW, patches in Lorenzo's branch have no conflicts with Agustin's patch set + my mbigen one, so after a pull request to Rafael, could them (Agustin's patch set + my mbigen one) go via one tree such as Marc's one for 4.11? I know it's a little bit late but those patches are quite self-contained, which Agustin's changes are conditional on the ACPI_GENERIC_GSI config which is only available with ARM64 ACPI and others (interrupt combiner and mbigen) are specific to QC and Hisilicon platforms. Marc, Lorenzo, could you give some comments that how can we proceed those patches (Agustin's patch set + my mbigen one)? It's really critical for us, thank you very much. Best Regards Hanjun
