Subject: [PATCH 37/38] KVM: PPC: booke: Reinject performance monitor interrupts
Date: Wed, 29 Feb 2012 01:10:05 +0100	[thread overview]
Message-ID: <1330474206-14794-38-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1330474206-14794-1-git-send-email-agraf@suse.de>

When we get a performance monitor interrupt, we need to make sure that
the host receives it. So reinject it like we reinject the other host
destined interrupts.
