Hi!

I'm debugging overheats on v4.9-rc1... which did not seem to happen in
v4.8-rc1. I'm running basically "nice make -j 3" on kernel... cpus are
fully loaded. 

%Cpu(s):  7.5 us, 18.5 sy, 72.6 ni,  0.0 id,  0.0 wa,  0.0 hi,  1.5
si,  0.0 st
KiB Mem:   3087096 total,  2993076 used,    94020 free,    52900
buffers
KiB Swap:  1681428 total,    60900 used,  1620528 free.  1183664
cached Mem

Still, cpus don't stay on maximum frequency on v4.8-rc1. (I suspect
that may be why machine does not overheat).

Is that expected behaviour? Any ideas?
