After migrating most of the information in
Documentation/filesystems/proc.txt to the proc(5) man page,
Jim Paris pointed out to me that the description of SwapFree
in the man page seemed wrong. I think Jim is right,
but am given pause by fact that that text has been in
Documentation/filesystems/proc.txt since at least 2.6.0.
Anyway, I believe that the patch below fixes things.

Yes, this goes back to 2003 when the /proc/meminfo doc has been added.

Want me to forward it on? (Lots of documentation stuff gets grabbed by
whoever maintains what it's documenting, this looks like it might fall
through the cracks...)
