From c1667e409764bb43a8196e40d01c409326d54a96 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Tue, 11 May 2010 09:41:25 +0300 Subject: [PATCH] kvm: fix 80000001.EDX supported bit filtering On AMD some bits from 1.EDX are reported in 80000001.EDX. The mask used to copy bits from 1.EDX to 80000001.EDX is incorrect resulting in unsupported features passed into a guest.
