Irrespective of your reply to Wei's similar request (where you've
provided links to mails showing crashes) I'd like you to explain
this better. This is in particular because I don't really see what
"recent changes in the iommu mapping logic" you talk about. The
code change itself looks okay, despite me not being overly happy
with the use of min() here, which iirc was already commented
about.
