While at it, made the configs a bit closer to those from Ubuntu:
* disabled IDE drivers which are now barely maintained anyway;
* disabled some debugging facilities (verboseness of some drivers,
etc.);
* made some often used modules like vfat, fuse, ata_piix, etc.,
built-in.
* and so forth.
Among other things:
* BFQ was updated to v8r7 for 4.9.0
* AUFS was updated to version 4.9-20161219
* inotify-increase-max-user-watches.patch was dropped: it is better to
tune such things from user space instead.
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.
