From b3b06c7eb7820cea5c15f9faa4964044284c5399 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Tue, 3 Mar 2015 16:12:12 -0500 Subject: [PATCH] x86/xen/apic: WARN with details. We should not be writting to the APIC registers under Xen PV. But if we do instead of just giving an blanket warning - include some details to help troubleshoot.
