Looks good to me - via which tree would you like to see this merged upstream?

I'd prefer the arm64 tree as arm64 is (the most) affected by the issue
in practice.

I'm happy for this to go via another tree if that's simpler; I'm not
aware of anything that's likely to conflict in the arm64 tree.

Catalin, Andrey, Andrew, any preference?

I don't have any. arm64 tree is fine by me.

For the patchset:

Cheers!

Following [1], I intend to change patch 1 to start at task_stack_page(t)
rather than task_thread_info(task) + 1, to keep things simple.

I assume that your Reviewed-by would still apply in that case?

Thanks,
Mark.
