Subject: [PATCH 08/11] KVM: x86: Don't set arch.cr0 in kvm_set_cr0
Date: Wed, 24 Feb 2010 18:59:17 +0100	[thread overview]
Message-ID: <1267034360-5907-9-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1267034360-5907-1-git-send-email-joerg.roedel@amd.com>

The vcpu->arch.cr0 variable is already set in the
architecture specific set_cr0 callbacks. There is no need to
set it in the common code.
This allows the architecture code to keep the old arch.cr0
value if it wants. This is required for nested svm to decide
if a selective_cr0 exit needs to be injected.
