[SRU][Yakkety][PATCH 0/3] Fixes for lp1646574

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1646574

== SRU Justification ==
This bug affects several users on Yakkety.  It causes the mouse cursor 
to be invisible.

This bug affects a number of different systems with Nvidia 10 Series (Pascal) GPUs. 
When using Nouveau, the cursor is drawn in the top left corner of the 
screen and appears to be stuck there despite the user being able to move 
around and click anywhere.

Three commits in mainline resolve this bug.  These commits are included 
in mainline as of 4.10-rc1.  All three are clean cherry picks.
