Subject: [PATCH 4.3-stable 0/5] Disable automatic numa balancing on UMA

Automatic NUMA balancing only makes sense on NUMA machines but was enabled
in 4.3 on UMA by commit 2a1ed24 ("sched/numa: Prefer NUMA hotness over
cache hotness") and is still enabled in 4.3.3 despite the fixes being in
mainline. With this series applied, UMA has zero automatic NUMA-related
page table updates as expected.
