Subject: [PATCH 08/15] arm/arm64: kvm: Set vcpu->cpu to -1 on vcpu_put
Date: Sat, 28 Dec 2013 11:15:40 +0000 [thread overview]
Message-ID: <1388229347-24185-9-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1388229347-24185-1-git-send-email-marc.zyngier@arm.com>
From: Christoffer Dall <christoffer.dall@linaro.org>
The arch-generic KVM code expects the cpu field of a vcpu to be -1 if
the vcpu is no longer assigned to a cpu. This is used for the optimized
make_all_cpus_request path and will be used by the vgic code to check
that no vcpus are running.
