Hi,

Here is my current queue of TCE/KVM patches.

1/6 is a bugfix for https://bugzilla.redhat.com/show_bug.cgi?id=1620360
2/6..5/6 are to help with testing https://bugzilla.redhat.com/show_bug.cgi?id=1613190
6/6 is a small cleanup


This is based on sha1
11da3a7 Linus Torvalds "Linux 4.19-rc3".

Please comment. Thanks.


Alex, I cc: you to keep you informed that
[RFC 1/6] did change drivers/vfio/vfio_iommu_spapr_tce.c but
this one does not.
