Subject: [PATCH linux v2 7/9] xen/events: fifo: use xen_vcpu_id mapping
Date: Thu, 30 Jun 2016 17:56:41 +0200 [thread overview]
Message-ID: <1467302203-22399-8-git-send-email-vkuznets@redhat.com> (raw)
In-Reply-To: <1467302203-22399-1-git-send-email-vkuznets@redhat.com>
EVTCHNOP_init_control has vCPU id as a parameter and Xen's idea of vCPU id
should be used. Use the newly introduced xen_vcpu_id mapping to convert
it from Linux's id.
