This should be the thing that fixed the problem fine for people (or at
least arca-39 fixed it ;). Now I have perfect reports of the arca-39 mm
from the guys that sent the mm bug report to linux-kernel. I guess the
only interesting thing in my patch for this issue is my change you
mentioned above (and that I am using from a lot of time, and since I
started hacking the mm myself I never had mm problems anymore btw ;). With
the patch above Stephen' s patch is not needed, I don' t know if it can be
still helpful though (since I have not read it in details yet).
