[GIT PULL] etnaviv for 4.6

[Lucas Stach]

Hi Dave,

the Etnaviv pull is mostly code cleanups courtesy of Russell King this
time, improving readability of certain parts of the driver a lot.

Notable changes:
- correctness fixes to the GPU cache flushing when switching execution
state and when powering down the GPU
- reduction of time spent in hardirq-off context
- placement improvements to the GPU DMA linear window, allowing the
driver to properly work on i.MX6 systems with more than 2GB of RAM 

Regards,
Lucas
