Bug description:
[Impact]
Due to upstream Kubernetes issue #127844, Multi-Gen LRU has been
requested by Google to be disabled until a permanent fix is
implemented. This feature unintentionally changed the output of
kubelet's memory usage calculations in an unexpected way.
[Fix]
Disabled Multi-Gen LRU in the kernel config.
[Test Case]
Compile and boot test.
[Where things could go wrong]
If this fix is unsuccessful, memory usage calculations will not return
to as they were before GKE 1.30.
