Fine with me.

Combining this with Julia's patches looks a bit risky to me and surely
needs testing.  I expect the problematic case is both native and acpi
hotplug being enabled.  When the guest uses acpi hotplug nobody will
turn on slot power on the pcie root port ...

I'd suggest to just revert to pcie native hotplug for 6.2.  Give acpi
hotplug another try for 7.0, and post patches early in the devel cycle
then instead of waiting until -rc0 is released.

take care,
  Gerd
