Subject: [PATCH 8/8] perf/x86/rapl: Get quirk state from new probe framework
Date: Mon, 18 Mar 2019 19:21:16 +0100	[thread overview]
Message-ID: <20190318182116.17388-9-jolsa@kernel.org> (raw)
In-Reply-To: <20190318182116.17388-1-jolsa@kernel.org>

Getting the apply_quirk bool from new rapl_model_match array.

And because apply_quirk was the last remaining piece of data
in rapl_cpu_match, replacing it with rapl_model_match as device
table.

The switch to new perf_msr_probe detection API is done.
