Subject: Re: [patch 02/10] cpu/hotplug: Prevent overwriting of callbacks

Oh hai!

I have kernel panic on boot here after this patch, 4.10-rc1 with this 
commit (dc280d93623927570da279e99393879dbbab39e7) reverted boots fine.

Potato-quality photo of incomplete traceback of 4.10-rc1 panic can be 
found at https://ojab.ru/IMG_20161227_015233.jpg (unfortunately I can't 
figure out how to increase resolution to catch a full trace and I don't 
have a serial terminal).

CPU here is 'AMD Phenom(tm) II X4 905e Processor' (4 core, 4 threads).
