[SRU][Xenial][PULL] Xenial update to 4.4.138 stable release (LP: #1777389)

[Juerg Haefliger]

BugLink: https://bugs.launchpad.net/bugs/1777389

This is a pull request for the update of Xenial to upstream stable
release 4.4.138.

Skipped the following already-applied patches:
  * Input: elan_i2c - add ELAN0612 (Lenovo v330 14IKB) ACPI ID (applied as:
    UBUNTU: SAUCE: Input: elan_i2c - add ELAN0612 to the ACPI table)

One patch required trival context adjustments, the rest applied cleanly.
Compile-tested all supported architectures.
