Plan C: we can follow the Al Viro's proposal about %n like in this patch.
The same applies to udp, fib (the /proc/net/route file), rt_cache and
sctp debug. This is minus ~150-200 bytes for each.

When drivers call request_module(), it tries to do something with UNIX
sockets and triggers a 'runaway loop modprobe net-pf-1' warning. Avoid
this by initialising AF_UNIX support earlier.

ASSERT_RTNL uses mutex_trylock to test whether the rtnl_mutex is
held. This bogus warnings when running in atomic context, which
f.e. happens when adding secondary unicast addresses through
macvlan or vlan or when synchronizing multicast addresses from
wireless devices.
Mid-term we might want to consider moving all address updates
to process context since the locking seems overly complicated,
for now just fix the bogus warning by changing ASSERT_RTNL to
use mutex_is_locked().

Noticed by Alan Cox.
The IFF_UP test is a bit racey, because other entities
outside of this driver's ioctl handler can modify that
state, even though this ioctl handler runs under
lock_kernel().

Commit b716bb91 ("iwlwifi: Cancel scanning upon association") moved the
test of priv->vif in iwl{3945,4964}_mac_config_interface() outside of
where priv->mutex is held, but still tries to do mutex_unlock() on
return. This is clearly wrong and triggers a nasty lockdep warning when
this codepath is triggered. Fix this by removing the mutex_unlock().

This patch updates mesh EID values, some of which where conflicting with
already-approved 11h EIDs (pointed out by Tomas Winkler). I wanted to use the
values suggested in the last available 802.11 draft (2.0) but it assigns 50 to
MESH_CONFIG, the same value than EXT_SUPP_RATES. Using the values proposed in
the draft incremented by one.

Some mainboards/CPUs don't allow DMA masks bigger than a certain limit.
Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this
case a 64-bit b43 device would always fail to acquire the mask.
Implement a workaround to fallback to lower DMA mask, as we can always
also support a lower mask.

The put routine first decrements the users counter and then
(if it is zero) locks the sta_bss_lock and removes one from
the list and the hash.
Thus, any of ieee80211_sta_config_auth, ieee80211_rx_bss_get
or ieee80211_rx_mesh_bss_get can race with it by finding a
bss that is about to get kfree-ed.
Using atomic_dec_and_lock in ieee80211_rx_bss_put takes care
of this race.

This adds a workaround for invalid bluetooth SPROM settings
on ASUS PCI cards.
This will stop the microcode from poking with the BT GPIO line.
This fixes data transmission on this device, as the BT GPIO line
is used for something TX related on this device
(probably the power amplifier or the radio).
This also adds a modparam knob to help debugging this in the future,
as more devices with this bug may show up.

There are two structures named wmm_info and wmm_param, they are used while
parsing the beacon frame. (Check the function ieee802_11_parse_elems).
Certain APs like D-link does not set the fifth bit in WMM IE.
While sending the association request to n-only ap it checks for wmm_ie.
If it is set then only ieee80211_ht_cap is sent during association request.
So n-only association fails.
And this patch fixes this problem by copying the wmm_info to wmm_ie,
which enables the "wmm" flag in iee80211_send_assoc.

The LEDS infrastructure itself does not require anything
that a platform dependant upon HAS_IOMEM.
The individual drivers do, but they are properly guarded
with the necessary platform dependencies.
One can even imagine a hypervisor based LED driver that
a platform without HAS_IOMEM might have.

As it stands it's impossible to use any authentication algorithms
with an ID above 31 portably. It just happens to work on x86 but
fails miserably on ppc64.
The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.
After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature. For current
applications, the best solution IMHO is to allow all algorithms when
the bit masks are all ~0.
The following patch does exactly that.
This bug was identified by IBM when testing on the ppc64 platform
using the NULL authentication algorithm which has an ID of 251.

The del_timer() function doesn't guarantee, that the timer callback
is not active by the time it exits.
Thus, the fib6_net_exit() may kfree() all the data, that is required
by the fib6_run_gc(). The race window is tiny, but slab poisoning can
trigger this bug.
Using del_timer_sync() will cure this.

Expose dev_id to userspace, because it helps to disambiguate between
interfaces where the MAC address is unique.
This should allow us to simplify the handling of persistent naming for
S390 network devices in udev -- because it can depend on a simple
attribute of the device like the other match criteria, rather than
having a special case for SUBSYSTEMS=="ccwgroup".

=======================
Since rose_route_frame() does not use rose_node_list we can safely
remove rose_node_list_lock spin lock here and let it be free for
rose_get_neigh().

_urb_free is an alias for kfree... making code longer & harder to

The functions time_before, time_before_eq, time_after, and time_after_eq
are more robust for comparing jiffies against other values.
A simplified version of the semantic patch making this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@ change_compare_np @
expression E;
@@
(
- jiffies <= E
+ time_before_eq(jiffies,E)

- jiffies >= E
+ time_after_eq(jiffies,E)

+ time_before(jiffies,E)

Herbert Xu's commit fb93134dfc2a6e6fbedc7c270a31da03fce88db9, entitled
"[TCP]: Fix size calculation in sk_stream_alloc_pskb", has triggered a
bug in the 5701 where the 5701 DMA engine will corrupt outgoing
packets. This problem only happens when the starting address of the
packet matches a certain range of offsets and only when the 5701 is
placed downstream of a particular Intel bridge.
This patch detects the problematic bridge and if present, readjusts the
starting address of the packet data to a dword aligned boundary.

Code within NS_DEBUG_SPINLOCKS contained deprecated cli()/sti()
function calls. NS_DEBUG_SPINLOCKS and the associated code seems to
be of little use these days so the strategy of removing this code
rather then updating it to use spinlocks has been taken.
