Ronald "bad idea" expanded:

"Mixing generic and platform specific code makes harder for people 
willing to port to other architectures the optimizations track them, 
makes harder to debug and usually lead to entangled situations."

As you said and I did before, the best is provide a patchset from a git 
tree, possibly public so the various steps needed to reach a proper code 
could be reviewed simply and possibly different people can help better 
to reach this goal.
