Hi Greg, Sasha,
Please consider backporting a1df829ead5877d4a1061e976a50e2e665a16f24
("ACPI/IORT: Do not blindly trust DMA masks from firmware").
It should apply all the way back to 5.5 and addresses an issue that
affects one of my machines with broken firmware.
If that's not feasible, at least 5.10 should get it.
Cheers,
Moritz

There are no "active" kernel trees from 5.5-5.9 at the moment, so 5.10
is the only one to apply it to, which Sasha already did!
thanks,
