From 72c452b2064321ae8b511508dbc80a7fd586a656 Mon Sep 17 00:00:00 2001 From: Chris J Arges Date: Fri, 24 Jul 2015 13:18:59 -0500 Subject: [PATCH] Fix: disable kvm probe if lapic.h isn't found In a typical distribution if just linux-headers is installed, lapic.h will not be installed. We should check if that file exists and not build the module.
