From b36585a0a3c169612f3105139464a2da1d3ecc03 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Wed, 23 Nov 2016 13:38:45 +0100 Subject: [PATCH] xen/events: use xen_vcpu_id mapping for EVTCHNOP_status EVTCHNOP_status hypercall returns Xen's idea of vcpu id so we need to compare it against xen_vcpu_id mapping, not the Linux cpu id.
