[PATCH] powercap/rapl: add support for cpu model 0x3f

From: Jason Baron
Date: Wed Aug 13 2014 - 16:33:32 EST


I've confirmed that monitoring the package power usage as well
as setting power limits appear to be working as expected. However,
I do see in the logs:

[ 5.082632] intel_rapl: RAPL domain core detection failed
[ 5.088370] intel_rapl: RAPL domain uncore detection failed

So I'm not sure if the h/w simply doesn't support that, or if the
driver could be improved here. In any case, adding the 0x3f makes
the driver useful for me. Tested aginst cpu:

Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
