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.
The kernel was updated to version 4.2.3.
3rd party additions (ndiswrapper) have been dropped.
The fixes for e1000e and mt7601u have been added as well, see
"kernel-patches-and-configs" project, branch v4.2.x.
Most external components have been removed to simplify maintenance.
The following ones are kept because they are more important and/or
maintained well in upstream:
- BFQ
- AUFS
- ndiswrapper
- several bug fixes
reiser4 is kept too but disabled by default until its maintainers update
it for kernel 4.x.
