This resulted from my commit
ca99ca14c which introduced a mutex_trylock

debugging is enabled, the above warns the user when we are in fact
exectuting in interrupt context
interrupt context.
After some discussion, It seems that a semaphore is the proper mechanism to use
here. While mutexes are defined to be unusable in interrupt context, no such
condition exists for semaphores (save for the fact that the non blocking api
calls, like up and down_trylock must be used when in irq context).

Adopt the fast retransmit/recovery idea in established state by
re-arming the SYNACK timer after the fast (SYNACK) retransmit. The

"With this one we have:
- One patch for moving the LLCP code into net/nfc.
It fixes a build annoyance reported by Dave Miller caused by the fact
that the LLCP code object targets are not in the same directory as the
Makefile trying to build them is. It prevents us from doing e.g.
make net/nfc/llcp/sock.o
Moving the LLCP code into net/nfc and not making it optional anymore
makes sense as LLCP is a fundamental piece of the NFC specifications
and thus should be in the core NFC directory.
- One patch that fixes the missing dependency against RFKILL. Without it NFC
fails to properly build when it's builtin and CONFIG_RFKILL=m."

====================
The following patchset contains relevant updates for the Netfilter
tree, they are:
* Enhancements for ipset: Add the counter extension for sets, this
information can be used from the iptables set match, to change
the matching behaviour. Jozsef required to add the extension
infrastructure and moved the existing timeout support upon it.
This also includes a change in net/sched/em_ipset to adapt it to
the new extension structure.
* Enhancements for performance boosting in nfnetlink_queue: Add new
configuration flags that allows user-space to receive big packets (GRO)
and to disable checksumming calculation. This were proposed by Eric
Dumazet during the Netfilter Workshop 2013 in Copenhagen. Florian
Westphal was kind enough to find the time to materialize the proposal.
* A sparse fix from Simon, he noticed it in the SCTP NAT helper, the fix
required a change in the interface of sctp_end_cksum.

netfilter: move skb_gso_segment into nfnetlink_queue module
skb_gso_segment is expensive, so it would be nice if we could
avoid it in the future. However, userspace needs to be prepared
to receive larger-than-mtu-packets (which will also have incorrect
l3/l4 checksums), so we cannot simply remove it.
The plan is to add a per-queue feature flag that userspace can
set when binding the queue.
The problem is that in nf_queue, we only have a queue number,
not the queue context/configuration settings.
This patch should have no impact other than the skb_gso_segment
call now being in a function that has access to the queue config
data.
A new size attribute in nf_queue_entry is needed so
nfnetlink_queue can duplicate the entry of the gso skb
when segmenting the skb while also copying the route key.
The follow up patch adds switch to disable skb_gso_segment when
queue config says so.

Merge branch 'master' of git://git./linux/kernel/git/jkirsher/net-next
Jeff Kirsher says:
====================
This series contains updates to e1000e, igb and ixgbe.
There are 2 patches in this series which could be applied to net,
but since Linus is so very close to releasing 3.9, I do not think
it prudent to try and push these into net at this time. I have CC'd
stable on these patches so that they can queue them up as soon as
3.9 gets released.
The 2 patches are:
e1000e: fix numeric overflow in phc settime method
ixgbe: fix EICR write in ixgbe_msix_other
Richard provides a fix for e1000e by using a helper function from time.h
to resolve a unintended overflow in the PTP settime function.
Bruce provides a fix to wait for NAPI to be done with the current context
after disabling interrupts and then disable NAPI when the interface
is going down. This fixes a possible "unable to handle kernel paging
request" panic in net-next.
Andi Kleen provides a patch for igb to use mdelay instead of udelay
when we needed 100000us.
Jacob provides a fix for ixgbe to simply mask the lower 16bits off so that
ixgbe_msix_other does not write them in the EICR, which causes them to
remain high and be properly handled by the clean_rings interrupt routine
as normal.
Emil cleans up the logic in ixgbe_setup_loopback_test() to only access
registers applicable to the MAC type. In addition, removes majority
of the AUTOC register reads by using a cached value instead to avoid
writing corrupted values to AUTOC due to bad FW. Emil also add support
for disabling link during boot time. Lastly, he provides a patch which
adds the MAC type to the version in ethtool_regs which will make it
easier to check the MAC type when dumping registers with ethtool.
There is a separate ethtool tool patch which is dependent upon Emil's
last patch of the series to add the MAC type to the version in
ethtool_regs, which will be sent separately.

Series done against the net-next tree as of commit
37fe0660981d7a "net:
fix address check in rtnl_fdb_del"
We have successfully tested the series on net-next, except for getting
the VF link info issue I have reported earlier today on netdev, we
see the problem for both ixgbe and mlx4 VFs. Just to make sure get
VF config is working OK with patch #6 - we have run it over 3.8.8 too.
We added to the V1 series two patches that disable HW timestamping
when running over a VF, as this isn't supported yet.
