Subject: Bad rss-counter is back on 3.14-stable

Hi all,

Dave, I saw you mention that you were seeing the "Bad rss-counter" line
on 3.15-rc1, but I couldn't find any follow-up on this to see if anyone
figured it out, or did it just "magically" go away?

I ask as Brandon is seeing this same message a lot on a 3.14.4 kernel,
causing system crashes and problems:

Anyone have any ideas of a 3.15-rc patch I should be including in
3.14-stable to resolve this?

thanks,

greg k-h
