This change introduced a regression with PCI passthrough which
stopped working. Guest kernel reports :

   [    0.156501] zpci: PCI is not supported because CPU facilities 69 or 71 
are not available

and other devices (ap, ccw) are impacted too I think.

Is it something we could test with the mainstream CI, or does this
requires specific hardware?

I think you need a s390x LPAR with PCI adapters. TCG won't work.
Not a very common system.
