Chris Wilson 262b6d363f drm/i915: Invalidate the relocation presumed_offsets along the slow path ... In the slow path, we are forced to copy the relocations prior to acquiring the struct mutex in order to handle pagefaults. We forgo copying the new offsets back into the relocation entries in order to prevent a recursive locking bug should we trigger a pagefault whilst holding the mutex for the reservations of the execbuffer. Therefore, we need to reset the presumed_offsets just in case the objects are rebound back into their old locations after relocating for this exexbuffer - if that were to happen we would assume the relocations were valid and leave the actual pointers to the kernels dangling, instant hang.
