[PATCH] Make swap accounting default behavior configurable

[Michal Hocko]

Hi Andrew,
could you consider the following patch for the Linus tree, please?
The discussion took place in this email thread 
http://lkml.org/lkml/2010/11/10/114.
The patch is based on top of 151f52f09c572 commit in the Linus tree.

Please let me know if there I should route this patch through somebody
else.

Thanks!
