From 2ac138ca21ad26c988ce7c91d27327f85beb7519 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Fri, 28 Jun 2013 18:15:15 +1000 Subject: [PATCH] powerpc/perf: Drop MMCRA from thread_struct In commit 59affcd "Context switch more PMU related SPRs" I added more PMU SPRs to thread_struct, later modified in commit b11ae95. To add insult to injury it turns out we don't need to switch MMCRA as it's only user readable, and the value is recomputed by the PMU code.
