Fix a bunch of related crashes in amdgpu that occur when shadow page tables are kicked out of the GART.
One of the issues was that during command submission, we rely on a device-global evictions counter to skip some of the work of page-table validation. The driver was never informed of evictions from GART, so this series adds an evict parameter to ttm_bo_driver::move_notify.
There's still the evict parameter on ttm_bo_driver::move which is used by radeon and nouveau for the call to ttm_bo_move_accel_cleanup. The 'evict' parameter there should probably be more accurately called 'wait', but unless that wait can always be avoided, the evict parameter on ttm_bo_driver::move needs to stay.
Please review!
