Boulan, Can you please help our debugging?
can you disable following config option at once?

1. CONFIG_DRM_I915
2. CONFIG_RELAY
3. CONFIG_MSPEC
4. VIDEOBUF_DMA_SG

I mean
- if anyone return VM_FAULT_OOM, this issue occur.
- very few subsys can return VM_FAULT_OOM in their own fault handler.
- I hope investigate this is core mm issue or not.
(unfortunatelly, I haven't find any dubious recent mm change..)

Thanks.
