Bug is prevalent on 4.8 kernels too.

Title:
"Out of memory" errors after upgrade to 4.4.0-59
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
I recently replaced some Xenial servers, and started experiencing "Out
of memory" problems with the default kernel.
We bake Amazon AMIs based on an official Ubuntu-provided image (ami-
e6b58e85, in ap-southeast-2, from https://cloud-
images.ubuntu.com/locator/ec2/). Previous versions of our AMI
included "4.4.0-57-generic", but the latest version picked up
"4.4.0-59-generic" as part of a "dist-upgrade".
Instances booted using the new AMI have been using more memory, and
experiencing OOM issues - sometimes during boot, and sometimes a while
afterwards. An example from the system log is:

I have a hunch that this may be related to the fix for
