Subject: [PATCH 11/16] KVM: PPC: Book3S: Enable IRQs during exit handling
Date: Sun, 06 May 2012 14:20:55 +0000 [thread overview]
Message-ID: <1336314060-32640-12-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1336314060-32640-1-git-send-email-agraf@suse.de>
While handling an exit, we should listen for interrupts and make sure to
receive them when they arrive, to keep our latencies low.
