Thanks for the report. I have a fix already: http://lkml.kernel.org/r/20191004134624.46216-1-catalin.marinas@arm.com I was hoping Andrew had sent it to Linus before -rc3 but it doesn't seem to be in mainline yet. Linus, could you please merge the patch above? I can send it again if it's easier. Thanks. -- Catalin
