Manivannan, not sure if you are able to provide an updated patch for 6.12 where the revert is missing right now? FWIW I applied the patch at https://lore.kernel.org/stable/20260320172335.29778-1-john@kernel.doghat.io/ on top of 6.12.82-rc1 today and booted on an AMD system to test. It has context issues but still applies fine, and I can confirm that my IOMMU groups are no longer messed up. As a result have been able to pass through 2 separate PCI cards to 2 separate VMs which I am unable to do without the revert.
