Comment 5 for bug 1750021

Xenial does not have 83e3c48729d9ebb7af5a31a504f3fd6aff0348c4. Though, linux-hwe 4.13 has been shipped for Xenial. So, on the kernel side, there is nothing to fix on our 4.4 kernels, but on the makedumpfile side, that still needs to be fixed if we want to have some of those kernels dumpable.
