Subject: [RFC][PATCH 2/3] Allow any LAPIC to accept PIC interrupts.
Date: Tue, 8 Jun 2010 13:55:02 -0400 [thread overview]
Message-ID: <1276019703-18136-3-git-send-email-clalance@redhat.com> (raw)
In-Reply-To: <1276019703-18136-1-git-send-email-clalance@redhat.com>
If the guest wants to accept timer interrupts on a CPU other
than the BSP, we need to remove this gate.
