Date: Tue, 28 Jun 2016 18:47:26 +0200 From: Vitaly Kuznetsov <vkuznets@...hat.com> To: xen-devel@...ts.xenproject.org Cc: linux-kernel@...r.kernel.org, x86@...nel.org, Stefano Stabellini <sstabellini@...nel.org>, Boris Ostrovsky <boris.ostrovsky@...cle.com>, David Vrabel <david.vrabel@...rix.com>, Juergen Gross <jgross@...e.com>, Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com>, Julien Grall <julien.grall@...rix.com> Subject: [PATCH linux 5/8] xen/events: use xen_vcpu_id mapping in events_base 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.
