Hi all,

I changed the patch subject to reflect the content, becoming more
general.

1) I removed the ack from Christian and Jason even far as
   I understand they gave it for the functionality more than for the
   implementation.
   @Jason, @Christian, please can I get back your acked-by with these changes?

2) previous patch had another name:
   [PATCH v3 0/1] s390: virtio: let arch choose to accept devices without IOMMU feature
   id: Message-Id: <1592390637-17441-2-git-send-email-pmorel@linux.ibm.com>

3) The new version generalize the validation of the features by the
   architecture, making it not IOMMU_PLATFORM specific anymore inside
   virtio.c

   The architecture specific code for s390 is now testing the virtio
   features.

4) Since I reworked the patch I also moved the arch specific code
   from arch/s390/mm/init.c to arch/s390/kernel/to uv.c

5) Finaly, I splitted the patch into generic virtio and arch
   specific code.

Regards,
Pierre
