From 83e267d797e0e69d0ac5741f5dc88a2df3ebb3a0 Mon Sep 17 00:00:00 2001 From: Stuart Yoder Date: Wed, 30 Apr 2014 18:34:23 -0500 Subject: [PATCH] powerpc: move epapr paravirt init of power_save to an initcall some restructuring of epapr paravirt init resulted in ppc_md.power_save being set, and then overwritten to NULL during machine_init. This patch splits the initialization of ppc_md.power_save out into a postcore init call.
