This is my current queue of patches to add acceleration of TCE
updates in KVM. This has a long history and was rewritten pretty
much completely again, this time I am teaching KVM about VFIO
containers. Some patches (such as 01/15) could be posted
separately but I keep all of them here to make review easier
(if the concept turns out be wrong - then I might still want
to have 01/15).
Please comment. Thanks.
