~swap prefetch
[snip]
Put me and the users out of our misery and merge it now
[snip]

For the record; it merges, builds, and runs cleanly on x86_64 vanilla+CFS provided sched-add_above_background_load is also merged (you need the old one that adds an inline to sched.h, not the new one that depends on SD-isms).  I believe that is already merged with -mm anyway.

I'd also be interested to see if there is a better way of doing what above_background_load() does with CFS, I think v18 added some functionality along these lines...
