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.
