[PATCH v2 stable 6.1 0/8] s390 KVM PCI backports for 6.1

Hi,

This patchset backports the s390 KVM PCI fixes to stable-6.1. The patchset
includes one dependency patch (patch 1) from Jason Gunthorpe, to export
free_uid(). This is needed to resolve a compilation error. I have resolved
all other merge conflicts and tested them on s390.

Thanks
Farhan
