[sorry for the delay in testing, was at the hospital waiting for
 a new baby, and the free wi-fi had the ssh port blocked]

I'm running 3.10-rc4 with your patch plus the 3-line fixup applied and my 
various tests are solid so far.

It would be nice to get this applied, without the patch it's trivial to 
oops/lock any kernel going back to 3.2 and probably earlier (I haven't 
tested older than 3.2 yet).
