Updates to ib_peer_memory requested by Nvidia

This bug is awaiting verification that the linux/5.13.0-23.23 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-impish' to 'verification-done-impish'. If the problem still exists, change the tag 'verification-needed-impish' to 'verification-failed-impish'.

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!

This bug is awaiting verification that the linux/5.11.0-42.46 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results.

This bug was fixed in the package linux - 5.15.0-17.17

---------------
linux (5.15.0-17.17) jammy; urgency=medium

  * jammy/linux: 5.15.0-17.17 -proposed tracker (LP: #1957809)

 -- Andrea Righi <email address hidden> Thu, 13 Jan 2022 17:11:21 +0100

It appears that the reason verification-needed-focal is applied here is because these patches were included in the linux-intel flavor, whose description says "A kernel image for Intel IOTG devices." I'm not sure what the expectations are for verifying bugs with that flavor - should they all be done on the target hardware? If so, I do not have access to the hardware to do so.

For this specific issue, I'll go ahead and mark verified with the following justification:

 (1) The only consumer of the IB Peer Memory interface at this time is the nvidia driver stack, and we do not appear to provide pre-compiled nvidia drivers for the -intel flavor at this time. Now, a user could install an nvidia-dkms package and build their own modules but,

 (2) This appears to be the first version of linux-intel in the focal series, so it can not possibly be a regression against an earlier version.
