Linus Torvalds 28f3d71761 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull more networking updates from David Miller:
 "Ok, everything from here on out will be bug fixes."

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (293 commits)
  tcp: take care of overlaps in tcp_try_coalesce()
  ipv4: fix the rcu race between free_fib_info and ip_route_output_slow
  mm: add a low limit to alloc_large_system_hash
  ipx: restore token ring define to include/linux/ipx.h
  if: restore token ring ARP type to header
  xen: do not disable netfront in dom0
  phy/micrel: Fix ID of KSZ9021
  mISDN: Add X-Tensions USB ISDN TA XC-525
  gianfar:don't add FCB length to hard_header_len
  Bluetooth: Report proper error number in disconnection
  Bluetooth: Create flags for bt_sk()
  Bluetooth: report the right security level in getsockopt
  Bluetooth: Lock the L2CAP channel when sending
  Bluetooth: Restore locking semantics when looking up L2CAP channels
  Bluetooth: Fix a redundant and problematic incoming MTU check
  Bluetooth: Add support for Foxconn/Hon Hai AR5BBU22 0489:E03C
  Bluetooth: Fix EIR data generation for mgmt_device_found
  Bluetooth: Fix Inquiry with RSSI event mask
  Bluetooth: improve readability of l2cap_seq_list code
  Bluetooth: Fix skb length calculation
