Andrew/David - please don't pull this for now.

We're solving some cross-over between this series and Vlastimil's
set of fixes from anthropic:

https://lore.kernel.org/linux-mm/20261027-pgalloc-ai-hotfixes-v1-0-9c7d1aca801e@xxxxxxxxxx/

Have discussed with Vlastimil, and i'm going to pull patches 4/9 and 5/9
from his series onto this series when i respin this for his updates.
That should keep the backport issues self-contained on this series.
