The fix is fairly simple. We need to tell kmemleak to ignore PUD
allocations and never report them as leaks. We can also tell it not to
scan the PGD, because it will never find pointers in there. However it
will still notice if we allocate a PGD and then leak it.

Thanks.

No problem. I forgot to add, that it’d be great, if you tagged this
for the stable series too.
