We first add the notion of objects being migratable under the object lock to i915 gem, and add some asserts to verify that objects are either locked or pinned when the placement is checked by the gem code. Patch 2 and 3 deals with updating the i915 gem bookkeeping after a TTM move, Patch 4 moves system over from shmem to TTM for discrete Note that the mock device doesn't consider itself discrete so the TTM system path is not checked by the mock selftests. v2: - Style fixes (reported by Matthew Auld) - Drop the last patch (migration) It needs selftests and some additional work. - Unconditionally add VM_IO at mmap time.
