Subject: [Qemu-devel] [PATCH] Fix messed up MSR_IA32_PERF_STATUS
Date: Mon, 29 Sep 2008 20:57:58 +0200	[thread overview]

Fix messed up MSR_IA32_PERF_STATUS

During a merge (probably on my side) the MSR_IA32_PERF_STATUS entry got 
lost in the wrmsr handler. The code is obviously rdmsr though, so let's 
shove it back to where it belongs.
