Subject: [patch V3 18/28] x86/perf/intel_rapl: Make Knights Landings support functional

In-Reply-To: 20160222220733.632098221@linutronix.de

[-- Attachment #1: x86-perf-intel_rapl--Make-Knights-Landings-support-functional.patch --]
[-- Type: text/plain, Size: 912 bytes --]

The Knights Landings support added the events and the detection case, but then
returns 0 without actually initializing the driver.

Fixes: 3a2a7797326a4 "perf/x86/intel/rapl: Add support for Knights Landing (KNL)"
