Subject: [PATCH KERNEL] xen/events: use xen_vcpu_id mapping for EVTCHNOP_status
Date: Wed, 23 Nov 2016 13:38:45 +0100 [thread overview]
Message-ID: <1479904725-12812-1-git-send-email-vkuznets@redhat.com> (raw)
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.
Suggested-by: Radim Krcmar <rkrcmar@redhat.com>
