Btw. I expect this patch to introduce some trivial conflict with a patch in Andrew's queue which cleans up some memory management stuff. This: "mm/SPARC: use common help functions to free reserved pages" Just so we are prepared when it happens. Stephen will tell us...

Common hibernation code looks at num_physpages during suspend and restore. Restore is able to be called from initcall, which is before initmem freeing. This case leads to restore fail.
