Subject: [PATCH v1 0/3] PCI fixes for s390

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.

Thanks
