From d92edd814e3c9d9105de55b14c8958b1f8f20269 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 6 Jul 2011 10:41:47 -0400 Subject: [PATCH] xen/pci: Provide #ifdef CONFIG_ACPI to easy code squashing. In the past we would guard those code segments to be dependent on CONFIG_XEN_DOM0 (which depends on CONFIG_ACPI) so this patch is not stricly necessary. But the next patch will merge common HVM and initial domain code and we want to make sure the CONFIG_ACPI dependency is preserved - as HVM code does not depend on CONFIG_XEN_DOM0.
