Subject: [PATCH linux 5/8] xen/events: use xen_vcpu_id mapping in events_base
Date: Tue, 28 Jun 2016 18:47:26 +0200	[thread overview]
Message-ID: <1467132449-1030-6-git-send-email-vkuznets@redhat.com> (raw)
In-Reply-To: <1467132449-1030-1-git-send-email-vkuznets@redhat.com>

EVTCHNOP_bind_ipi and EVTCHNOP_bind_virq pass 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.
