P.S. I know I need to create proper SRU bug texts, I'll add them before upload once I got to complete the tests and know what to write there.

Reviewing this one.

Thanks for the MP, Christian!

The s390x bits are OK, but I found what seems to be a problem in the hunk that adds "--disable-pie" to the configure flags, so I'm marking this as Needs Fixing. Feel free to upload once this fixed.

Thanks Sergio, that indeed was an issue - Fixed (And period added).
It would have been spotted on testing, but that way it is much better - Thanks.

+Subject: [PATCH] s390x/s390-virtio-ccw: Reset PCI devices during subsystem
+ reset
+
+Currently, a subsystem reset event leaves PCI devices enabled, causing
+issues post-reset in the guest (an example would be after a kexec).  These
+devices need to be reset during a subsystem reset, allowing them to be
+properly re-enabled afterwards.  Add the S390 PCI host bridge to the list
+of qdevs to be reset during subsystem reset.
