It's trivial to merge the MADV_FREE #defines into the kernel

Until the semantics of the implementation is cut into stone by having it
in the kernel I'll not start using it.
The current MADV_DONTNEED implementation conforms to the
semantics of MADV_FREE :)
With MADV_FREE you can get back either your old data, or
a freshly zeroed out new page. Always getting back the
second alternative is conformant :)
