Subject: [PATCH 3/6] KVM: VMX: Move real-mode interrupt injection fixup to vmx_complete_interrupts()
Date: Tue, 27 Jul 2010 16:19:37 +0300	[thread overview]
Message-ID: <1280236780-5847-4-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1280236780-5847-1-git-send-email-avi@redhat.com>

This allows reuse of vmx_complete_interrupts() for cancelling injections.
