The patches were originally posted at: https://lore.kernel.org/linux-arm-kernel/20240412131908.433043-1-ryan.roberts@arm.com/ ... and were originally merged upstream in v6.10-rc1. I'm requesting this be merged to stable on behalf of a partner who wants to get the benefit of this series in Debian 12.
