I just wanted to point out that the revert of "PCI: Enable ACS after 
configuring IOMMU for OF platforms" is missing here despite being queued 
in the 6.1 & 6.6 rcs (it is meant to be reverted from 6.12 as well). I 
noticed when updating to 6.12.82-rc1 today as I was bit by the 
regression (all my IOMMU groups messed up).

The revert for 6.12 is in fact here:
https://lore.kernel.org/stable/20260320172335.29778-1-john@xxxxxxxxxxxxxxxx/

but unfortunately easily missed as shown by the confusion here (same 
thread):
https://lore.kernel.org/stable/99426bd8-32e5-4246-9d3b-772e136bc078@xxxxxxxxxxxxx/

subsequently clarified by the patch author here (also same thread):
https://lore.kernel.org/stable/5hng5r6q525scbclramuv2h2hphljbcsscwohvrs7teuedgfvl@ncr7tqhr4l4z/

Other than that 6.12.82-rc1 boots and runs fine for me on the one AMD 
Ryzen system I've tried it on.

Thanks,
Eddie
