Anything received after that time might be too late.

Reverting 83c9f9e994f5c963fc652a52befc120699dcc591 fixes the problem.
Its description suggests that it fixes a real bug, though, so copying Paul for input.
Thanks for the bisection and report.
Paul, any ideas? Why doesn't this also fail in 4.7?
thanks,
greg k-h
Hi Greg, Guenter,
The easiest way to fix this is likely to backport a60ae81e5e59 ("MIPS:
CM: Fix mips_cm_max_vp_width for UP kernels") which went into mainline
in the 4.7 cycle. Apologies for overlooking the need for that one in stable.
Thanks,
Paul
