From d0174c721900ff807b95ac4ab23191ffcb7511c7 Mon Sep 17 00:00:00 2001 From: Nathan Fontenot Date: Thu, 14 Jan 2010 09:52:44 +0000 Subject: powerpc: Move cpu hotplug driver lock from pseries to powerpc Move the defintion and lock helper routines for the cpu hotplug driver lock from pseries to powerpc code to avoid build breaks for platforms other than pseries that use cpu hotplug.
