From 9dd4b2944c46e1fdbd0a516c221c8a2670cbf005 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 29 Aug 2013 07:43:52 -0500 Subject: [PATCH] ARM: xen: only set pm function ptrs for Xen guests xen_pm_init was unconditionally setting pm_power_off and arm_pm_restart function pointers. This breaks multi-platform kernels. Make this conditional on running as a Xen guest and make it a late_initcall to ensure it is setup after platform code for Dom0.
