Subject: [PATCH 3.16.y-ckt 200/216] powercap / RAPL: add support for CPU model 0x3f

3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Baron <jbaron@...mai.com>

commit 64c7569c065564a066bb44161f904b4afc9f3e3a upstream.

I've confirmed that monitoring the package power usage as well as setting power
limits appear to be working as expected. Supports the package and dram domains.

Tested aginst cpu:

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