Hi,

Please consider applying the following patches to v4.4.y.

The following patches were found to be missing in v4.4.y by the ChromeOS
missing patches robot. The patches meet the following criteria.

- The patch referenced in the Fixes: tag has been applied to v4.4.y
- The patch itself has not been applied to v4.4.y

All patches have been applied to v4.4.y and chromeos-4-4. Resulting images
have been build- and runtime-tested on real hardware running chromeos-4.4
and with virtual hardware on kerneltests.org.

Note: I generated this notification manually. I hope I'll have some
automation soon; until then I'll send similar notifications for other
kernel branches as I find the time.
