[PATCH] cpuset: remove test for null cpuset from alloc code path
Remove a couple of more lines of code from the cpuset hooks in the page allocation code path. There was a check for a NULL cpuset pointer in the routine cpuset_update_task_memory_state() that was only needed during system boot, after the memory subsystem was initialized, before the cpuset subsystem was initialized, to catch a NULL task->cpuset pointer. Add a cpuset_init_early() routine, just before the mem_init() call in init/main.c, that sets up just enough of the init tasks cpuset structure to render cpuset_update_task_memory_state() calls harmless.
