Earlier, the patches were kept in the respective branches of a separate
project, https://abf.io/soft/kernel-patches-and-configs. And before that -
in the custom tarballs.
Now all the patches are kept here along with the spec file and are
applied the default way rather than by separate scripts. This should
make the maintenance of the patches as well as the experiments with the
new ones a lot easier.
The previous scheme seemed to offer a bit more flexibility (different
patch sets for different cases) at the cost of maintenance. But as it
turned out, that flexibility was not worth it and was rarely used,
at most.
