untar the attached file, then "patch -p1 <" in corresponding subdirectories. It would be better to untar the file in an empty directory, so you can understand which subdirectories are newly created (ex. hardware/realtek is newly created), then within these newly created subdirectoies, you need to "git init" first, then do "patch -p1<" to adopt all newly added files and subdirectories.
