2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------ From: Catalin Marinas <[email protected]> commit 9b090f2da85bd0df5e1a1ecfe4120b7b50358f48 upstream. Kmemleak frees objects via RCU and when CONFIG_DEBUG_OBJECTS_RCU_HEAD is enabled, the RCU callback triggers a call to free_object() in lib/debugobjects.c. Since kmemleak is initialised before debug objects initialisation, it may result in a kernel panic during booting. This patch moves the kmemleak_init() call after debug_objects_mem_init().
