Pawel Jakub Dawidek 44ce1efd91 Change type of kmem_used() and kmem_size() functions to uint64_t, so it
doesn't overflow in arc.c in this check:

	if (kmem_used() > (kmem_size() * 4) / 5)
		return (1);

With this bug ZFS almost doesn't cache.

Only 32bit machines are affected that have vm.kmem_size set to values >=1GB.
