[Intel-gfx] [PATCH i-g-t v2 00/13] Implement sw_sync test

[robert.foss at collabora.com]

From: Robert Foss <robert.foss at collabora.com>

This is a resubmission of v2.

This series implements the sw_sync test and the lib/sw_sync helper functions for said test.

Gustavo Padovans sw_sync series was just de-staged in gregkh-staging/staging-next [1], and this test is targeted at verifying the functionality implemented in that series. 

The sw_sync subtests range from very basic tests of the sw_sync functionality, to stress testing and randomized tests.
