From 19e3d60d49f05a9de0ef06c60703f31d4acd5f17 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 4 May 2015 17:58:01 +0200 Subject: [PATCH] x86: Let x2APIC support depend on interrupt remapping or guest support We are able to use x2APIC mode in the absence of interrupt remapping on certain hypervisors. So it is fine to disable IRQ_REMAP without having to give up x2APIC support.
