Before you go add more configuration goo on your end, let me see what the other
kvm@ maintainers think.  Maybe we'll get lucky and everyone is on-board already.

Hmm, maybe use a page table walker approach, and only send emails if every node of
the tree says yes?  Only getting email some of the time would be pretty darn
annoying though :-/

s/kinda silly/flat out stupid, given how easy it is to filter/ignore email.

Crazy idea: as a stopgap, what if sashiko emails linux-kernel@vger.kernel.org if
the list hasn't opted-in?  It wouldn't be as good as getting mails sent directly
to me, but subscribing to and filtering linux-kernel@vger.kernel.org mails is very
doable.  And even without subscribing to linux-kernel@vger.kernel.org, for those
of us that heavily utilize b4, it would better than clicking through a web site.
