Subject: v4.8-rc1: thinkpad x60: running at low frequency even during kernel build

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?
