Looks like some s390 KVM maintainers weren't on CC, added Janosch and
Claudio (Omar please make sure to include them for next version)...

s390(-kvm) maintainers,

Do you think you would take this via s390-kvm (or s390) with Alex's ack
on the vfio parts, or vice versa? (Please note: this is not yet the
final version of this series)

For perspective, the changes are mostly in arch/s390 and the
s390-specific vfio_pci_zdev code.

s390 changes:
 arch/s390/include/asm/pci.h      |  2 +
 arch/s390/pci/pci.c              | 85 +++++++++++++++++++++++++-------
 arch/s390/pci/pci_debug.c        | 11 ++++-
 drivers/vfio/pci/vfio_pci_zdev.c | 60 ++++++++++++++++++++++

VFIO changes:
 drivers/vfio/pci/vfio_pci_core.c |  4 ++
 drivers/vfio/pci/vfio_pci_priv.h | 18 +++++++
 include/uapi/linux/vfio.h        | 29 +++++++++++

Thanks,
Matt
