Hi Linus,
Thomas tasked me with sending out a few urgent fixes after the giant
MSI rework that landed in 6.2, as both s390 and powerpc ended-up
suffering from it (they do not use the full core code infrastructure,
leading to these previously undetected issues). Details in the tag
below.
Many thanks to Guenter, Matthew and Niklas for reporting the issues.
Please pull,
M.

powerpc/msi: Fix deassociation of MSI descriptors (2022-12-17 10:58:48 +0000)
----------------------------------------------------------------
MSI fixes for 6.2:
- Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the architecture
does not make use of irq domains instead of returning 0, which is pretty
limiting.
- Check for the presence of an irq domain when validating the MSI iterator,
as s390/powerpc won't have one.
- Fix powerpc's MSI backends which fail to clear the descriptor's IRQ field
on teardown, leading to a splat and leaked descriptors.
