We've previously agreed that not all kernel features (drivers,

should be for the 4.4 branch.

Are members able to share their kernel .config files, showing which
features are enabled? Or would you prefer to specify your needs at a
slightly higher level?
Answering this question is important to discard features in 4.4 that are
not of CIP interest so we can severely reduce the amount of effort that
we will need to do in terms of fixes analysis, security etc. in the future.

Please take some time to provide feedback.
Sorry for the late reply!

Please find attached an x86 kernel configuration from early product
development using kernel 4.4.

This product uses nearly-COTS server hardware due to needed computation
power, but also comes with nice embedded requirements like longterm
maintenance - and as a special need, real-time support, so we use
Linux-Ipipe/Xenomai here.

This means two things:
* many included drivers (especially in net and storage) are only
activated "to be prepared" for future hw replacements
* Feel free to either include Xenomai on your list as a used "kernel
feature" or to ignore the related options.

So same as with the config from Hidehiro Kawai: please let me know if
you need prioritized list of drivers or other features!

Kind regards,
