When locking a region, we currently clamp to a PAGE_SIZE as the minimum lock region. While this is valid for Midgard, it is invalid for Bifrost,
While the spec does seem to state it's invalid for Bifrost - kbase didn't bother with a lower clamp for a long time. I actually think this is in many ways more of a spec bug: i.e. implementation details of the round-up that the hardware does. But it's much safer following the spec ;) And it seems like kbase eventually caught up too.
Yeah, makes sense. Should I drop the Cc: stable in that case? If the issue is purely theoretical.
