Resending the stragglers again.                                                                                  

This set is part of a larger effort attempting to clean-up W=1                                                   
kernel builds, which are currently overwhelmingly riddled with                                                   
niggly little warnings.

What's next/master?
I'm not sure if this is a joke, or not? :)

next/master == Linux Next.  The daily merged repo where all of the
*-next branches end up to ensure interoperability.  It's also the
branch that is most heavily tested by the auto-builders to ensure the
vast majority of issues are ironed out before hitting Mainline.
This is net-next:

https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/
Looks like net-next gets merged into next/master:

commit 452958f1f3d1c8980a8414f9c37c8c6de24c7d32
Merge: 1eabba209a17a f50e2f9f79164
Author: Stephen Rothwell [off-list ref]

    Merge remote-tracking branch 'net-next/master'

So I'm not sure what it's conflicting with.

Do you have patches in net-next that didn't make it into next/master
for some reason?

I'll try to rebase again tomorrow.

Hopefully I am able to reproduce your issue by then.

I guess so, I have the same problem as Jakub, see below. I had to use 'git am -3' to apply you 
series. As you can see, git falls back to 3 way merge for patch 1, which means your series is close 
to but not fully in sync with net-next.

Seeing as you went to all that effort, I thought it was only fair that
I did the same.  After some digging my tentative conclusion is that
Linux -next is up-to-date with net-next, but net-next is not
up-to-date with Linux -next.

I think this patch is conflicting:

 smc91x: remove GPIOLIB dependency.

Was that taken in via another tree?  If not resolved there is a chance
that this may cause a conflict when net-next is merged into Mainline.

..

Okay, so what would you like me to do?  Would you like me to re-submit
the set based only on net-next, or are you happy with your 3-way
merge?

I'll do as you ask.

Yes, rebase your patches on net-next, recheck everything builds okay
and resubmit. You should always develop against the tree that will
merge your patches. I appreciate for your janitorial work using
linux-next is more expedient, but as you can see it causes trouble,
this is not the first time your patches don't apply to net-next IIRC.
