git clone git://github.com/vsyrjala/linux.git
cd linux
git checkout dp_mst_props
zcat /proc/config.gz > .config
make -j$(nproc)
# just keep hitting enter to select the default value
# for all the new config options it asks you about

# you seem to be running fedora so you can
# probably just build an rpm for yourself with
make binrpm-pkg
