Hi,

I came across some issues in PCI code for s390 while working on VFIO error
recovery for s390 PCI devices [1]. These patches can be indepedently applied and
has no depedency on error recovery patch series. We would like to get these
patches merged as they do fix some existing issues.

[1] https://lore.kernel.org/all/20250924171628.826-1-alifm@linux.ibm.com/

ChangeLog
---------
v1 -> v2
- Re-work patch 1 on setting per_func_slot flag. The flag is set if platform
enables per function pci slots (currently only enabled for s390).
- Drop R-b tags for patch 1.

Thanks
Farhan
