Increase kernel security by ensuring that normal kernel accesses
are unable to access userspace addresses. This can help prevent
use-after-free bugs becoming an exploitable privilege escalation
by ensuring that magic values (such as LIST_POISON) will always
fault when dereferenced.

The implementation uses CPU domains when !CONFIG_ARM_LPAE and
disabling of TTBR0 page table walks with CONFIG_ARM_LPAE.
