Doesn't build for me.
arch/powerpc/platforms/pseries/suspend.c:29:36: fatal error:
../../kernel/cacheinfo.h: No such file or directory
#include "../../kernel/cacheinfo.h"
Anshuman must have worked around that somehow to test it previously?
Removing the include doesn't fix it, it needs cacheinfo_cpu_on/offline().
