That's what I thought. So leaving it as a default y is fine by me. But I would not merge this patch now until we get some useful functionality for arm64. The x86-related cleanup patches can be merged separately via the corresponding trees (it's up to the ACPI and x86 maintainers). -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Ah, sorry I didn't describe it clearly. since there is no shipping board with ACPI tables, so ACPI will disabled in the very early stage and FDT still have chance to be unflattened, so will not break DT booting in this patchset.
