The wiki page http://wiki.qemu.org/Contribute/SubmitAPatch
tries to describe our usual process for reviewing code
submissions. If you make sure your changes follow the
guidelines described there and then send them to the mailing
list as a series of patch emails in the right format, we
can start reviewing the code.
