Merge branch 'pci-device-recovery' into features
Niklas Schnelle says:
===================
This patch series enhances the introspectability of the PCI device
recovery for firmware. Until now when Linux performs recovery in
response to a firmware error report. For example, until now firmware
debug data would have no indication if the recovery was successfull or
if it failed, for example due to KVM pass-through.
Improve on this by reporting recovery status as well as some debug
information such as device driver name and s390dbf/pci_msg/sprintf logs
via the SCLP Write Event Data Action Qualifier 2 (Log Data provided)
mechanism.
