arch/s390/net/pnet.c uses ccwgroup function dev_is_ccwgroup()
in pnetid_by_dev_port().
For s390 the net/smc code makes use of function pnetid_by_dev_port().
Make sure ccwgroup is built into the kernel, if smc is to be built
into the kernel.

OSN devices currently spend an awful long time in qeth_l2_set_online()
until various unsupported HW cmds time out. This has been broken for
over two years, ever since
commit d22ffb5a71 ("s390/qeth: fix IPA command submission race")
triggered a FW bug in cmd processing.
Prior to commit 782e4a7921 ("s390/qeth: don't poll for cmd IO completion"),
this wait for timeout would have even been spent busy-polling.
The offending patch was picked up by stable and all relevant distros,
and yet noone noticed.
OSN setups only ever worked in combination with an out-of-tree blob, and
the last machine that even offered HW with OSN support was released back
in 2015.
Rather than attempting to work-around this FW issue for no actual gain,
add a deprecation warning so anyone who still wants to maintain this
part of the code can speak up. Else rip it all out in 2021.

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".
When the callback is called for special messages, the driver creates
an uevent for the received message. The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.
udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
