[UBUNTU 20.04] s390x/pci: do not allow to create more pci functions than configured via CONFIG_PCI_NR_FUNCTIONS |

Description will follow |
PCI Functions with UIDs >128 are currently not accounted correctly in the s390x/pci code. Furthermore, the code allows that more than CONFIG_PCI_NR_FUNCTIONS are created. This can lead to issues with data structures which were only allocated for CONFIG_PCI_NR_FUNCTIONS.
This has been fixed in the following upstream commit:
969ae01bab2fe938b4c8324836038b5ac1c78fac
("s390/pci: Fix zpci_alloc_domain() over allocation") |

("s390/pci: Fix zpci_alloc_domain() over allocation") |
SRU Justification:
==================
[Impact]
* PCI Functions with UIDs >128 are currently not accounted correctly in the s390x/pci (zPCI) code.
* Furthermore, the code allows that more than CONFIG_PCI_NR_FUNCTIONS are created.
* This can lead to issues with data structures which were only allocated for CONFIG_PCI_NR_FUNCTIONS.
[Fix]
* https://bugs.launchpad.net/ubuntu-z-systems/+bug/1874057/+attachment/5357850/+files/0001-s390-pci-Fix-zpci_alloc_domain-over-allocation-for-focal.patch
[Test Case]
* Set the kernel parameter CONFIG_PCI_NR_FUNCTIONS to a specific (reasonablly low) number.
* And check if more PCI functions can be created than specified by CONFIG_PCI_NR_FUNCTIONS (e.g. using a RoCE adapter) and watch for kernel message 'Adding PCI function ... failed'
[Regression Potential]
* There is regression potential can be considered as low, since:
* the zPCI cards are less wide spread than for example ccw adapters on s390x
* the fix got already upstream accepted in 5.7, hence upstream reviewed, too
* the modifications span just two files and both are s390x arch specific
[Other Info]
* the above patch-file is based on commit 969ae01bab2fe938b4c8324836038b5ac1c78fac ("s390/pci: Fix zpci_alloc_domain() over allocation"), but this backport was needed for getting this applied to focal master-next
* and this patch got upstream accepted with kernel v5.7-rc1, hence on the long term it should be in 'gorilla'
