[PATCH 3/5 v4] Export memory_sysdev_class

From: Nathan Fontenot
Date: Wed Oct 21 2009 - 10:44:36 EST


Export the memory_sysdev_class structure. This is needed so we can create
a 'release' file in sysfs in addition to the existing 'probe' file in
order to support DLPAR removal of memory on the powerpc/pseries platform.
The new 'release' file will be powerpc/pseries only.
