Message-ID: <55479709.4030901@siemens.com> Date: Mon, 04 May 2015 17:58:01 +0200 From: Jan Kiszka <jan.kiszka@...mens.com> To: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com> CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, x86 <x86@...nel.org> 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 if fine to disable IRQ_REMAP without having to give up x2APIC support.
