Subject: [PATCH 01/46] KVM: VMX: Make flexpriority module parameter reflect hardware capability
Date: Wed, 20 May 2009 14:17:58 +0300	[thread overview]
Message-ID: <1242818323-10413-2-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1242818323-10413-1-git-send-email-avi@redhat.com>

If the hardware does not support flexpriority, zero the module parameter.
