The following patches are required to properly support hibernation with
eoan:linux-aws (kernel 5.3).

All the SAUCE patches are required to improve swapoff performance after
a successful resume.

All these patches have been tested in the AWS environment with positive
results.

The following changes since commit 49363ee85deb05236c3527586cf6cea106e935a5:

  UBUNTU: Ubuntu-aws-5.3.0-1013.14 (2020-03-02 13:19:25 -0800)
