This same failure reproduces on -rc7 without any additional patches
applied, so I don't think it's related at all to Peter's queue.

Thanks Will, we will double check this.

It is false positive. Please ignore this issue. Sorry for inconvenient.
This build failure is caused by commit "RISC-V: Add kconfig option for QEMU virt machine" and already been fixed by commit "RISC-V: Only select essential drivers for SOC_VIRT config" in v5.6 but not in Peter's queue at that moment. These failure log should be ignored by bisect for this patch. We will enhance the bisect logic.
Thanks.

Ok, thanks for investigating this and letting us know.
