The following changes are part of the porting of the bind/unbind functionality. These changes reuse the shutdown codepaths in iGPU and dGPU and fix a locking issue with in gk20a_busy() where the usage count can lead to a deadlock during the driver shutdown. It fixes a racing condition with the gr/mm code by invalidating the sw ready flag while holding the busy lock JIRA: EVLR-1739 Change-Id: I62ce47378436b21f447f4cd93388759ed3f9bad1 Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1554959 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
