Hi Dave,
is the following thread and patch related to your problem,
I just happened to stumble upon it a few days ago:
https://lkml.org/lkml/2014/12/17/280 , http://marc.info/?l=linux-kernel&m=141876582909898&w=2 Re: post-3.18 performance regression in TLB flushing code
Linus already posted a fix to the problem, however I can't seem to find the matching commit in his tree (searching for "TLC regression" or "TLB cache").
Kind Regards
Matt
