You - the patch submitter - have to provide useful information to
those who review the patches and not the reviewers are supposed to
decode your sloppy commit log.

"... which I pulled from the MIPS tree"

Why should I assume that this is from mainline ?

You can think what you want, it's not the way it works.

You duplicate code, so the first thing to do is to replace the code
which you copied and make sure it is still fully functional. Then you
can add a second user to make the point that the generic code move is
actually useful. btw, pmtimer is the worst example for a good use case
as everything there is constant so we can do it at compile time.
