[UBUNTU 21.04] s390/pci: vfio-pci mmio being disabled erroneously

The the patches/commits needed were upstream accepted with 5.10:
12856e7acde4 "PCI/IOV: Mark VFs as not implementing PCI_COMMAND_MEMORY"
08b6e22b850c "s390/pci: Mark all VFs as not implementing PCI_COMMAND_MEMORY"
515ecd5368f1 "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from is_virtfn"
I'm updating the Hirsute entry to In Progress, since 5.10 will soon migrate to the Hirsute archive.

The patches are as follows:
60877c26d6ed "PCI/IOV: Mark VFs as not implementing PCI_COMMAND_MEMORY"
f87c055c0321 "s390/pci: Mark all VFs as not implementing PCI_COMMAND_MEMORY"
97011440b167 "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from is_virtfn"
already part of groovy, starting with Ubuntu-5.8.0-30.32.
And since we are already at level:
linux-generic | 5.8.0.31.36 | groovy-updates | s390x
I'm closing the groovy entry as Fix Released.

The patches are also partly in focal:
fb5c915cdd37 "PCI/IOV: Mark VFs as not implementing PCI_COMMAND_MEMORY"
23af8153d85e "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from is_virtfn"
They came in 'Focal update: v5.4.73 upstream stable release' LP 1902115.

However, 08b6e22b850c "vfio/pci: Decouple PCI_COMMAND_MEMORY bit checks from is_virtfn" is missing.
I checked all other upstream stable bugs for focal, this one is not addressed.

Hence this ticket boils down to cherry picking 08b6e22b850c "s390/pci: Mark all VFs as not implementing PCI_COMMAND_MEMORY" into focal master-next.

A kernel test build based on focal master-next completed and is shared here:

Thanks! I tested the provided focal build and was able to verify that it resolves the issue.

Re: groovy -- Sorry, my mistake I was not looking at the latest versions of groovy/focal when listing which patches needed backporting. I did also just now verify your assertion that this issue is already resolved in the latest groovy as well, so thanks again.

Thx Matthew for the quick test.

I've now submitted the kernel SRU for the remaining fix for focal:
https://lists.ubuntu.com/archives/kernel-team/2020-December/thread.html#115495
and changed the status to 'In Progress' for focal.

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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!

focal build successfully tested.

thx, I'm adjusting the tag accordingly

Now that kernel 5.10 landed in hirsute's release pocket:
linux-generic | 5.10.0.14.16 | hirsute
the 'hirsute' part can be updated to 'Fix Released".
