Yes, I suppose vhost DMAR patches will be based upon this one. I can postpone this patch until Jason wants to pick it up, but it actually does not hurt if we just enable it now, anyway no one is using it. So... I see no bad to merge this along with the series, so that we can reduce one entry from Jason's TODO list. :) Thanks! -- peterx
