One key problem is that nlm_xlp_defconfig does not configure NET anymore.
this is after 'scsi_netlink : Make SCSI_NETLINK dependent on NET instead
of selecting NET' was applied.

In fact, there are many more affected configurations; the change from
"select XXX" to "depends XXX" has far reaching consequences, as many
configurations are no longer valid. For mips alone I find that this commit
changes the following configurations.


e55_defconfig is almost the same as before, but only because CONFIG_NET
was not configured for it to start with. For all others, CONFIG_NET is
no longer set. This effectively means that out of 55 mips configurations,
11 or 20% are now bad. This is 3.17-rc5. vs. next-20140919.

Frankly, I don't think this change was really helpful. On the contrary,
we will be in a lot of trouble when this change makes it upstream.
It might be be a good idea to be much more careful when making such
changes. Cleaning up configuration dependencies is a laudable goal,
but when it breaks configurations all over the place it does more damage
than it is worth.
