6bbb6d99f3 net/mlx4_en: Optimize Rx fast path filter checks
Currently, RX path code that does RX filtering is not optimized
and does an expensive conversion. In order to use ether_addr_equal_64bits
which is optimized for such cases, we need the MAC address kept by the device
to be in the form of unsigned char array instead of u64. Store the MAC address
as unsigned char array and convert to/from u64 out of the fast path when needed.
Side effect of this is that we no longer need priv->mac, since it's the same
as dev->dev_addr.

This optimization was suggested by Eric Dumazet <eric.dumazet@gmail.com>

79aeaccd91 net/mlx4_en: Optimize loopback related checks in data path
Currently there are relatively complex conditional checks in the fast path,
for TX loopback enabling and resulting RX filter logic.
Move elaborate if's out of data path, replace them with a single flag
for each state and update that state from appropriate places.
Also, in native (non SRIOV) mode and not in loopback or in selftest,
there is no need to try and filter out packets that HW loopback-ed,
as in native mode we do not loopback packets anymore.

ff7c60c580 drm/ttm: fix fence locking in ttm_buffer_object_transfer, 2nd try
This fixes up

commit e8e89622ed
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Tue Dec 18 22:25:11 2012 +0100

    drm/ttm: fix fence locking in ttm_buffer_object_transfer

which leaves behind a might_sleep in atomic context, since the
fence_lock spinlock is held over a kmalloc(GFP_KERNEL) call. The fix
is to revert the above commit and only take the lock where we need it,
around the call to ->sync_obj_ref.

v2: Fixup things noticed by Maarten Lankhorst:
- Brown paper bag locking bug.
- No need for kzalloc if we clear the entire thing on the next line.
- check for bo->sync_obj (totally unlikely race, but still someone
  else could have snuck in) and clear fbo->sync_obj if it's cleared
  already.

There is a off-by-one error in qdisc_pkt_len_init() because

skb_mac_header() returns an out of bound value that was

12b0004d1d net: adjust skb_gso_segment() for calling in rx path
skb_gso_segment() is almost always called in tx path,
except for openvswitch. It calls this function when
it receives the packet and tries to queue it to user-space.
In this special case, the ->ip_summed check inside
skb_gso_segment() is no longer true, as ->ip_summed value
has different meanings on rx path.

This patch adjusts skb_gso_segment() so that we can at least
avoid such warnings on checksum.

6731d2095b tcp: fix for zero packets_in_flight was too broad
There are transients during normal FRTO procedure during which
the packets_in_flight can go to zero between write_queue state
updates and firing the resulting segments out. As FRTO processing
occurs during that window the check must be more precise to
not match "spuriously" :-). More specificly, e.g., when
packets_in_flight is zero but FLAG_DATA_ACKED is true the problematic
branch that set cwnd into zero would not be taken and new segments
might be sent out later.

e185483e6b team: allow userspace to take control over carrier
Some modes don't require any special carrier handling so
in these cases, the kernel can control the carrier as for
any other interface.  However, some other modes, e.g. lacp,
requires more than just that, so userspace needs to control
the carrier itself.

The daemon today is ready to control it, but the kernel
still can change it based on events.

This fix so that either kernel or userspace is controlling
the carrier.

ca99ca14c9 netpoll: protect napi_poll and poll_controller during dev_[open|close]
Ivan Vercera was recently backporting commit
9c13cb8bb4 to a RHEL kernel, and I noticed that,
while this patch protects the tg3 driver from having its ndo_poll_controller
routine called during device initalization, it does nothing for the driver
during shutdown. I.e. it would be entirely possible to have the
ndo_poll_controller method (or subsequently the ndo_poll) routine called for a
driver in the netpoll path on CPU A while in parallel on CPU B, the ndo_close or
ndo_open routine could be called.  Given that the two latter routines tend to
initizlize and free many data structures that the former two rely on, the result
can easily be data corruption or various other crashes.  Furthermore, it seems
that this is potentially a problem with all net drivers that support netpoll,
and so this should ideally be fixed in a common path.

As Ben H Pointed out to me, we can't preform dev_open/dev_close in atomic
context, so I've come up with this solution.  We can use a mutex to sleep in
open/close paths and just do a mutex_trylock in the napi poll path and abandon
the poll attempt if we're locked, as we'll just retry the poll on the next send
anyway.

I've tested this here by flooding netconsole with messages on a system whos nic
driver I modfied to periodically return NETDEV_TX_BUSY, so that the netpoll tx
workqueue would be forced to send frames and poll the device.  While this was
going on I rapidly ifdown/up'ed the interface and watched for any problems.
I've not found any.

b6ec447df9 Merge branch 'wireless'
John W. Linville says:

====================
Please consider this pull request for the 3.8 stream...

Included is a bluetooth pull.  Gustavo says:

"Two simple fixes for 3.8. One of the patches fixes a situation
where the connection wasn't terminated if a timeout ocurrs for LE
an SCO connections.  The other fixes prevent NULL dereference in the
SMP code, it is a security fix as well."

Along with those...

Hauke Mehrtens provides a couple of ssb and bcma bus fixes that
prevent oopses when unloading those modules.

Larry Finger provides and rtlwifi fix to avoid a "scheduling while
atomic" bug.

Last but certainly not least, Arend van Spriel bring a brcmsmac fix that
reworks the mac80211 .flush() callback in order to avoid the dreaded
brcms_c_wait_for_tx_completion warnings.  This one looks a little
large, but I think it is safe and isolated to brcmsmac in any case.

When btrfs_qgroup_reserve returned a failure, we were missing a counter

Additionally, the error handling code didn't take into account that we
dropped the inode lock which might require more cleanup.

Luckily, all the cleanup code we need is already there and can be shared
with reserve_metadata_bytes, which is exactly what this patch does.
