From abacaadc4144a8849782cc0917a624a7114ffbb1 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Mon, 2 Jun 2014 17:58:01 +0100 Subject: x86/xen: fix memory setup for PVH dom0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since af06d66ee32b (x86: fix setup of PVH Dom0 memory map) in Xen, PVH dom0 need only use the memory memory provided by Xen which has already setup all the correct holes. xen_memory_setup() then ends up being trivial for a PVH guest so introduce a new function (xen_auto_xlated_memory_setup()).
