Bao Liang Bluetooth: Set conn state to BT_DISCONN to avoid multiple responses
This patch fixes a minor issue that two connection responses will be sent
for one L2CAP connection request. If the L2CAP connection request is first
blocked due to security reason and responded with reason "security block",
the state of the connection remains BT_CONNECT2. If a pairing procedure
completes successfully before the ACL connection is down, local host will
send another connection complete response. See the following packets
captured by hcidump.

@sgruszka sgruszka iwl3945: remove plcp check
Patch fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=654599

Many users report very low speed problem on 3945 devices,
this patch fixes problem, but only for some of them.

For unknown reason, sometimes after hw scanning, device is not able
to receive frames at high rate. Since plcp health check may request
hw scan to "reset radio", performance problem start to be observable
after update kernel to .35, where plcp check was introduced.

Bug reporter confirmed that removing plcp check fixed problem for him.

@herbertx herbertx bridge: Fix mglist corruption that leads to memory corruption
The list mp->mglist is used to indicate whether a multicast group
is active on the bridge interface itself as opposed to one of the
constituent interfaces in the bridge.

Unfortunately the operation that adds the mp->mglist node to the
list neglected to check whether it has already been added.  This
leads to list corruption in the form of nodes pointing to itself.

Normally this would be quite obvious as it would cause an infinite
loop when walking the list.  However, as this list is never actually
walked (which means that we don't really need it, I'll get rid of
it in a subsequent patch), this instead is hidden until we perform
a delete operation on the affected nodes.

As the same node may now be pointed to by more than one node, the
delete operations can then cause modification of freed memory.

This was observed in practice to cause corruption in 512-byte slabs,
most commonly leading to crashes in jbd2.

Thanks to Josef Bacik for pointing me in the right direction.

@herbertx herbertx bridge: Fix timer typo that may render snooping less effective
In a couple of spots where we are supposed to modify the port
group timer (p->timer) we instead modify the bridge interface
group timer (mp->timer).

The effect of this is mostly harmless.  However, it can cause
port subscriptions to be longer than they should be, thus making
snooping less effective.

@herbertx herbertx bridge: Replace mp->mglist hlist with a bool
As it turns out we never need to walk through the list of multicast
groups subscribed by the bridge interface itself (the only time we'd
want to do that is when we shut down the bridge, in which case we
simply walk through all multicast groups), we don't really need to
keep an hlist for mp->mglist.

This means that we can replace it with just a single bit to indicate
whether the bridge interface is subscribed to a group.

@jjuhl jjuhl Net, USB, Option, hso: Do not dereference NULL pointer
In drivers/net/usb/hso.c::hso_create_bulk_serial_device() we have this
code:
...
	serial = kzalloc(sizeof(*serial), GFP_KERNEL);
	if (!serial)
		goto exit;
...
exit:
	hso_free_tiomget(serial);
...
hso_free_tiomget() directly dereferences its argument, which in the
example above is a NULL pointer, ouch.
I could just add a 'if (serial)' test at the 'exit' label, but since most
freeing functions in the kernel accept NULL pointers (and it seems like
this was also assumed here) I opted to instead change 'hso_free_tiomget()'
so that it is safe to call it with a NULL argument. I also modified the
function to get rid of a pointles conditional before the call to
'usb_free_urb()' since that function already tests for NULL itself -
besides fixing the NULL deref this change also buys us a few bytes in
size.
Before:
$ size drivers/net/usb/hso.o
   text    data     bss     dec     hex filename
  32200     592    9960   42752    a700 drivers/net/usb/hso.o

When a Virtual Machine is rebooted, KVM currently fails to issue a Function
Level Reset against any "Attached PCI Devices" (AKA "PCI Passthrough").  In
addition to leaving the attached device in a random state in the next booted
kernel (which sort of violates the entire idea of a reboot reseting hardware
state), this leaves our peer thinking that the link is still up.  (Note that
a bug has been filed with the KVM folks, #25332, but there's been no
response on that as of yet.)  So, we add a "->shutdown()" method for the
Virtual Function PCI Device to handle administrative shutdowns like a

Ian Campbell arp_notify: unconditionally send gratuitous ARP for NETDEV_NOTIFY_PEERS.
NETDEV_NOTIFY_PEER is an explicit request by the driver to send a link
notification while NETDEV_UP/NETDEV_CHANGEADDR generate link
notifications as a sort of side effect.

In the later cases the sysctl option is present because link
notification events can have undesired effects e.g. if the link is
flapping. I don't think this applies in the case of an explicit
request from a driver.

This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we
could add a new sysctl for this case which defaults to on.

This change causes Xen post-migration ARP notifications (which cause
switches to relearn their MAC tables etc) to be sent by default.

@cladisch cladisch hwmon: (jc42) more helpful documentation
The documentation lists standard numbers and chip names in excruciating
detail, but that's all it does.  To help mere mortals in deciding
whether to enable this driver, mention what this sensor is for and in
which systems it might be found.

Also add a link to the actual JC 42.4 specification.

@cladisch cladisch hwmon: (jc42) do not allow writing to locked registers
On systems where the temperature sensor is actually used, the BIOS is
likely to have locked the alarm registers.  In that case, all writes
through the corresponding sysfs files would be silently ignored.

To prevent this, detect the locks and make the affected sysfs files
read-only.

Tejun Heo workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'
There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'.  The former is the more prominent one.  The latter is
mostly used by workqueue and in a few other odd places.  Unify the

Tejun Heo workqueue: make sure MAYDAY_INITIAL_TIMEOUT is at least 2 jiffies long
MAYDAY_INITIAL_TIMEOUT is defined as HZ / 100 and depending on
configuration may end up 0 or 1.  Even when it's 1, depending on when
the mayday timer is added in the current jiffy interval, it may expire
way before a jiffy has passed.

Make sure MAYDAY_INITIAL_TIMEOUT is at least two to guarantee that at
least a full jiffy has passed before calling rescuers.

@jbrandeb jbrandeb e1000e: flush all writebacks before unload
The driver was not flushing all writebacks before unloading, possibly
causing memory to be written by the hardware after the driver had
reinitialized the rings.

This adds missing functionality to flush any pending writebacks and is
called in all spots where descriptors should be completed before the driver

Systems containing an 82599EB and running a backported driver from

@johnstultz-work johnstultz-work RTC: Revert UIE emulation removal
Uwe pointed out that my alarm based UIE emulation is not sufficient
to replace the older timer/polling based UIE emulation on devices
where there is no alarm irq. This causes rtc devices without alarms
to return -EINVAL to UIE ioctls. The fix is to re-instate the old
timer/polling method for devices without alarm irqs.

This patch reverts the following commits:
042620a - Remove UIE emulation
1daeddd - Cleanup removed UIE emulation declaration
b5cc8ca - Remove Kconfig symbol for UIE emulation

The emulation mode will still need to be wired-in with a following

@torvalds torvalds Expand CONFIG_DEBUG_LIST to several other list operations
When list debugging is enabled, we aim to readably show list corruption
errors, and the basic list_add/list_del operations end up having extra
debugging code in them to do some basic validation of the list entries.

However, "list_del_init()" and "list_move[_tail]()" ended up avoiding
the debug code due to how they were written. This fixes that.

So the _next_ time we have list_move() problems with stale list entries,
we'll hopefully have an easier time finding them..

@torvalds torvalds net: dont leave active on stack LIST_HEAD
Eric W. Biderman and Michal Hocko reported various memory corruptions
that we suspected to be related to a LIST head located on stack, that
was manipulated after thread left function frame (and eventually exited,
so its stack was freed and reused).

Eric Dumazet suggested the problem was probably coming from commit
4434572 (net: factorize
sync-rcu call in unregister_netdevice_many)

This patch fixes __dev_close() and dev_close() to properly deinit their
respective LIST_HEAD(single) before exiting.

EMC6D103:A1, and EMC6D102 (according to the data sheets), but used
unconditionally in the driver: 62[5:7], 6D[0:7], and 6E[0:7]. For that
