2016Q4 Intel Graphics Stack Recipe

STACK DESCRIPTION
This is a stack of individual graphics projects that have been tested together to generate a proven recipe against different hardware and software configurations. The notes highlight the most important features and bug fixes and also list all known issues.
The 2016Q4 highlights are:
One thing to highlight is the driver de-midlayering which has two main benefits: removing a lot of pointer dereferencing in the compiled binaries reducing complexity and also the Intel driver being in full control of the driver load and unload sequence.
HIGHLIGHTED NEW FEATURES OR FIXED BUGS
Kernel
Driver de-midlayering
Better tracking of pending and completed GPU requests
Fixes in tearing for multi-GPU machines
Complete and detailed list can be found at the maintainer's (Daniel Vetter) announcement
