This small patch-set fixes a corner-case bug in kernel queue handling, which was caused by using a function called sync_with_hw().
The patch-set removes this function, as it is not needed anymore. As a result, we need to replace cpu_relax() with schedule() in DQM, so this patch-set takes care of that as well.
I would like this fix to be in 3.19 so please review.
I'm not really too familiar with these corner cases, but the logic seems correct so series is: Acked-by: Alex Deucher alexander.deucher@amd.com
