Sorry, this was on 8-stable.

The only explicit followups were r212497 (ppc64) and r214194 (ia64).
Were there others?

I notice r211706 was initially marked "MFC after 3 weeks" but this was
never done.  I've found one posting that blames it for problems in
emacs but nothing else.  Is there a reason it wasn't MFC'd?
