Subject: [PATCH 07/10] KVM: PPC: Book3S: PR: Indicate we're out of guest mode
Date: Mon, 13 Aug 2012 03:21:32 +0200	[thread overview]
Message-ID: <1344820895-8475-8-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1344820895-8475-1-git-send-email-agraf@suse.de>

When going out of guest mode, indicate that we are in vcpu->mode. That way
requests from other CPUs don't needlessly need to kick us to process them,
because it'll just happen next time we enter the guest.
