Subject: [PATCH 06/10] arm/arm64: kvm: Set vcpu->cpu to -1 on vcpu_put
Date: Thu, 12 Dec 2013 11:55:45 -0800	[thread overview]
Message-ID: <1386878149-13397-7-git-send-email-christoffer.dall@linaro.org> (raw)
In-Reply-To: <1386878149-13397-1-git-send-email-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.
