1) Fix TX lockups in forcedeth due to an incorrect chipset ID check
   wrt. whether to enable a TX hw bug workaround or not.  Fix from
   Ayaz Abdulla.

2) Fix some virtualization problems by orphan'ing the SKB on TX
   in tun driver.  From Michael S. Tsirkin.

3) Some minor fallout from the slab.h cleanups in gigaset driver,
   from Tilman Schmidt.

4) hdlc_ppp can crash on rmmod due to lack of PPP tx queue flush,
   fix from Krzysztof Halasa.

5) Three fixes from Eric Dumazet:
   a) ip_dev_loopback_xmit() needs to use netif_rx_ni() since it sometimes
      is invoked from user context and therefore an explicit check and
      run of softirqs is necessary.
   b) dev_pic_tx() should not cache a socket TX queue selection unless
      the socket cache'd dst matches the one currently hung off of the
      skb
   c) Fix lockdep false positives in fib_trie

6) AF_PACKET erroneously restricts to init_net in some ioctls, fix
   from Daniel Lezcano.

7) iwlwifi active chain detection fix from Johannes Berg.

Please pull, thanks a lot!

Introduced by commit b91ecb00 that got pushed out today. That change removed 
an implicit sched.h inclusion that came in via slab.h.

The patch below fixes it by adding the sched.h dependency.

Note, i just found that my patch is not enough as we fail the build elsewhere as well:

drivers/isdn/gigaset/proc.c:52: error: 'TASK_UNINTERRUPTIBLE' undeclared (first use in this function)

i'd suggest a revert of b91ecb00 instead.

Maybe add the #include <linux/sched.h> into gigaset.h, instead of 
common.c?

IOW..

This compiled for me, although the only thing I tried was just turning all 
the gigaset options to 'y'. Maybe some other config doesn't work. So I 
committed it as likely to fix things.

Thanks Linus.

Ingo, let us know if there is still some problems in your
build tests.

I did a few tests and it looks good here!

I'll check it tomorrow - but i'd expect it to be enough, plus the all-yes 
thing is that matters most in practice in any case.

Thanks,

Yes, that's the correct fix. Thanks a lot!

For the record, the cause of the build failure was my removal of
#include <linux/usb.h> from gigaset.h, entailing the loss of one
indirect inclusion of sched.h. There's another indirect inclusion
of sched.h from gigaset.h via interrupt.h, hardirq.h and
smp_lock.h, but that one only operates if CONFIG_PREEMPT is set.
So the reason I did not see the build failure myself was that I
only tested with CONFIG_PREEMPT=y.
