This was already reported over here:

https://www.linux-mips.org/archives/linux-mips/2016-10/msg00120.html 

These 2 patches fix it:

https://patchwork.linux-mips.org/patch/14395/ 
https://patchwork.linux-mips.org/patch/14396/ 

I've asked Ralf if we can get those, along with a few others, in ASAP - 
preferrably for -rc3.

Thanks,
    Paul
