Kirill Korotaev 6997a6faaa [PATCH] sys_getppid oopses on debug kernel ...

sys_getppid() optimization can access a freed memory.  On kernels with
DEBUG_SLAB turned ON, this results in Oops.  As Dave Hansen noted, this
optimization is also unsafe for memory hotplug.

So this patch always takes the lock to be safe.
