From a50bcfb436da42dbd6005da681ed91bb768684f4 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 25 Aug 2017 18:02:01 -0700 Subject: stats: Move the swpipl function into the Alpha kernel stats. This stat is only incremented by Alpha. Also move the _hwrei into the Alpha stats object since it's the class that actually sets up and maintains that value and it probably should have been there all along.
