One condition before codel_Newton_step() was not good if
we never left the dropping state for a flow. As a result
rec_inv_sqrt was 0, instead of the ~0 initial value.

codel control law was then set to a very aggressive mode, dropping
many packets before reaching 'target' and recovering from this problem.

To keep codel_vars_init() as efficient as possible, refine
the condition to make sure rec_inv_sqrt initial value is correct

Many thanks to Anton Mich for discovering the issue and suggesting
a fix.

Here is a handful of fixes intended for 3.6.

Daniel Drake offers a cfg80211 fix to consume pending events before
taking a wireless device down.  This prevents a resource leak.

Stanislaw Gruszka gives us a fix for a NULL pointer dereference in
rt61pci.

Johannes Berg provides an iwlwifi patch to disable "greenfield" mode.
Use of that mode was causing a rate scaling problem in for iwlwifi.

commit be9f4a44 (ipv4: tcp: remove per net tcp_sock) added a
selinux regression, reported and bisected by John Stultz

selinux_ip_postroute_compat() expect to find a valid sk->sk_security
pointer, but this field is NULL for unicast_sock

It turns out that unicast_sock are really temporary stuff to be able
to reuse  part of IP stack (ip_append_data()/ip_push_pending_frames())

Fact is that frames sent by ip_send_unicast_reply() should be orphaned
to not fool LSM.

Note IPv6 never had this problem, as tcp_v6_send_response() doesnt use a
fake socket at all. I'll probably implement tcp_v4_send_response() to
remove these unicast_sock in linux-3.7

During probe, every function probed clears the recovery registers from
all functions on its path - thus signaling that given a future recovery
event, there will be no need to wait for those functions.

This is a flawed behaviour - each function should only be responsible
for its own bit.

Since this registers are handled during the load/unload routines,
this cleanup is removed altogether.

This is a fix for bug, introduced in 3.4 kernel by commit
1ab5ecb9 ("tun: don't hold network
namespace by tun sockets"), which, among other things, replaced simple
sock_put() by sk_release_kernel(). Below is sequence, which leads to
oops for non-persistent devices:

tun_chr_close()
tun_detach()				<== tun->socket.file = NULL
tun_free_netdev()
sk_release_sock()
sock_release(sock->file == NULL)
iput(SOCK_INODE(sock))			<== dereference on NULL pointer

This patch just removes zeroing of socket's file from __tun_detach().
sock_release() will do this.

Driver probe functions are generally __devinit so they will be
discarded after initialization for non-hotplug kernels.
This was found by a new warning after patch 6a228452 "stmmac: Add
device-tree support" adds a new __devinit function that is called
from stmmac_pltfr_probe.

Without this patch, building socfpga_defconfig results in:

WARNING: drivers/net/ethernet/stmicro/stmmac/stmmac.o(.text+0x5d4c): Section mismatch in reference from the function stmmac_pltfr_probe() to the function .devinit.text:stmmac_probe_config_dt()
The function stmmac_pltfr_probe() references
the function __devinit stmmac_probe_config_dt().
This is often because stmmac_pltfr_probe lacks a __devinit
annotation or the annotation of stmmac_probe_config_dt is wrong.

We allocate memory for 'req' with usb_alloc_urb() and then test
'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'.
If we enter that branch due to '!req' then there is no problem. But if
we enter the branch due to 'req' being != 0 and the 'rx_submit()' call
being false, then we'll leak the memory we allocated.
Deal with the leak by always calling 'usb_free_urb(req)' when entering
the branch. If 'req' happens to be 0 then the call is harmless, if it
is not 0 then we free the memory we allocated but don't need.

[Resending again, as the text was corrupted by the email client]

To speed up operations, QFQ internally divides classes into
groups. Which group a class belongs to depends on the ratio between
the maximum packet length and the weight of the class. Unfortunately
the function qfq_change_class lacks the steps for changing the group
of a class when the ratio max_pkt_len/weight of the class changes.

For example, when the last of the following three commands is
executed, the group of class 1:1 is not correctly changed:

tc disc add dev XXX root handle 1: qfq
tc class add dev XXX parent 1: qfq classid 1:1 weight 1
tc class change dev XXX parent 1: classid 1:1 qfq weight 4

Not changing the group of a class does not affect the long-term
bandwidth guaranteed to the class, as the latter is independent of the
maximum packet length, and correctly changes (only) if the weight of
the class changes. In contrast, if the group of the class is not
updated, the class is still guaranteed the short-term bandwidth and
packet delay related to its old group, instead of the guarantees that
it should receive according to its new weight and/or maximum packet
length. This may also break service guarantees for other classes.
This patch adds the missing operations.

Apparently, declaring a const array without initializer put it in

Since we really want dst_default_metrics be const to avoid any possible
false sharing and catch any buggy writes, I force a null initializer.

Pull IOMMU fixes from Joerg Roedel:
 "These patches fix a couple of issues.  First of all a few problems
  with ACS on x86 introduced in the last merge window, where ACS did not
  work on AMD and a NULL pointer dereference when there ran against
  SR-IOV devices.

  The patches fallen out of coccinelle checks fix a possible invalid
  memory reference and a possible memory leak.  The other patches mostly
  fix build errors and warnings and a wrong return value."

Pull sound fixes from Takashi Iwai:
 "Containing only a few really small/trivial fixes.  The only urgent fix
  is a regression fix of HDMI codec probing, introduced in 3.6-rc1.  The
  rest are HD-audio specific fixes and a copule of minor bug fixes in
  PCM core and the old emu10k1."

The same ID is twice in the quirk table, so the second one is not used.

When CONFIG_SND_VERBOSE_PRINTK=y is set, the debug print in
hda_auto_parser.c looks really ugly like:

  ALSA sound/pci/hda/hda_auto_parser.c:331    mono: mono_out=0x0
  ALSA sound/pci/hda/hda_auto_parser.c:334    dig-out=0x12/0x0
  ALSA sound/pci/hda/hda_auto_parser.c:335    inputs:
  ALSA sound/pci/hda/hda_auto_parser.c:339  Mic=0x11ALSA sound/pci/hda/hda_auto_parser.c:339  Line=0x10
  ALSA sound/pci/hda/hda_auto_parser.c:341
  ALSA sound/pci/hda/hda_auto_parser.c:343    dig-in=0x13

Better to put one item at each line.

devm_kfree should not have to be explicitly used.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,d;

x = devm_kzalloc(...)
...
?-devm_kfree(d,x);

Now that the auto model is the default, these quirks are redundant

This computer is confirmed working with model=auto on kernel 3.2.
Also, parsing fails with hda-emu with the current model.
