4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> commit 903ecd0bb970438c3a60c2c33ec9032d6443bf67 upstream. Everytime we use the logical context with execlists it becomes dirty (as the hardware will write the new register values afterwards, as well as the GPU state that will be used). We need to then flag the context as dirty everytime since after a swap-out/swap-in cycle the dirty flag will be cleared, and a further swap-out cycle will then loose the most recent GPU state.
