Subject: [PATCH 0/2] Fix MSR_IA32_PERF_STATUS
Date: Wed, 1 Sep 2010 10:34:55 +0300 [thread overview]
Message-ID: <1283326497-20206-1-git-send-email-avi@redhat.com> (raw)
MSR_IA32_PERF_STATUS is read-only, yet exposed for save/restore. This
generates annoying printk()s when userspace attempts to initialize it.
The value returned is also bogus, the comments appear to refer to another msr.
Fix both issues. Alex, please test with a guest Mac.
