Bug Description

[Impact]
ARM systems w/ an SMMUv3 that uses MSI control interrupts fail to initialize them, which can e.g. prevent detected device errors from being reported.

[Test Case]
dmesg | grep "failed to allocate MSIs"
grep arm-smmu-v3 /proc/interrupts

[Fix]
Upstream fixes that add support for the SMMUv3 device ID mapping index - which is required for MSI support - need to be included.

[Regression Risk]
By enabling these interrupts, we're allowing code to run that previously didn't, which could potentially do bad things. However, the interrupt handlers look pretty simple/straightforward, and I haven't seen any problems on a system that uses them w/ the fixes applied.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
