Subject: Re: [PATCH v2 05/11] MIPS: Switch to arch_topology
Hi Jiaxun,
I love your patch! Yet something to improve:
[auto build test ERROR on driver-core/driver-core-testing]
[also build test ERROR on pm/linux-next linus/master next-20200411]
[cannot apply to tip/perf/core tip/irq/core v5.6]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

Note: the linux-review/Jiaxun-Yang/MIPS-Topology-DeviceTree-CPU-rework-v2/20200412-113308 HEAD 8e8e9d4f7aa74359f2199773786ffe2fbb7877d0 builds fine.
It only hurts bisectibility.
