Subject: [PATCH 3/3] KVM: PPC: Book3S PR: MSR_DE doesn't exist on Book 3S
Date: Mon, 05 Nov 2012 04:17:28 +0000 [thread overview]
Message-ID: <20121105041728.GN22409@drongo> (raw)
In-Reply-To: <20121105034025.GK22409@drongo>
The mask of MSR bits that get transferred from the guest MSR to the
shadow MSR included MSR_DE. In fact that bit only exists on Book 3E
processors, and it is assigned the same bit used for MSR_BE on Book 3S
processors. Since we already had MSR_BE in the mask, this just removes
MSR_DE.
