Sebastian Ott aa5c8df398 [S390] qdio: fix init sequence
Reorder the initialization sequence of the qdio module to avoid
writing to an uninitialized debug feature entry. Also reorder
the exit function to restore a consistent cleanup path.

Yevgeny Petrilin c379474591 mlx4: Fixing bad size of event queue buffer
We should reduce the number of reserved completion queues from the total
number of entries. Since the queue size is power of two, not reducing the
reserved entries, caused a double queue size, which may lead to allocation
failures in some cases.

Patrick McHardy 04f482faf5 connector: convert to synchronous netlink message processing
Commits 01a16b21 (netlink: kill eff_cap from struct netlink_skb_parms)
and c53fa1ed (netlink: kill loginuid/sessionid/sid members from struct
netlink_skb_parms) removed some members from struct netlink_skb_parms
that depend on the current context, all netlink users are now required
to do synchronous message processing.

connector however queues received messages and processes them in a work
queue, which is not valid anymore. This patch converts connector to do
synchronous message processing by invoking the registered callback handler
directly from the netlink receive function.

In order to avoid invoking the callback with connector locks held, a
reference count is added to struct cn_callback_entry, the reference
is taken when finding a matching callback entry on the device's queue_list
and released after the callback handler has been invoked.

Philip A. Prindeville c031235b39 atm/solos-pci: Don't flap VCs when carrier state changes
Don't flap VCs when carrier state changes; higher-level protocols
can detect loss of connectivity and act accordingly. This is more
consistent with how other network interfaces work.

We no longer use release_vccs() so we can delete it.

release_vccs() was duplicated from net/atm/common.c; make the
corresponding function exported, since other code duplicates it
and could leverage it if it were public.

  genirq: Fix misnamed label in handle_edge_eoi_irq

Fix up crazy conflict in arch/powerpc/include/asm/qe_ic.h:

 - commit eead4d5c63 ("powerpc: qe_ic: Rename get_irq_desc_data and
   get_irq_desc_chip") made the helper functions use
   irq_desc_get_handler_data() instead of the legacy (and no longer
   existing) get_irq_desc_data.

 - commit d4db35e8dc ("powerpc/qe_ic: Fix another breakage from the
   irq_data conversion") used irq_desc_get_chip_data() instead.

According to Thomas, the former is the correct direct conversion, but it
does look like both should work (arch/powerpc/sysdev/qe_lib/qe_ic.c
seems to initialize both to the same thing), and the chip data in some
ways is the more logical.  Somebody should really decide on one of the
other.

This merge picks irq_desc_get_handler_data() as the straightforward pure
conversion to new names, as per Thomas.

Daniel Hellstrom c897dcf631 sparc32,leon: Fixed APBUART frequency detection
The UARTs may be located on different APB buses, thus have

different UART clock frequency. The system frequency is not
the same (but often) as the UART frequency, rather the APB bus
frequency that the APBUART is located at has the same
frequency, so this looks at the "freq" property instead.

Andrzej Zaborowski 7a635ea989 net/usb: Ethernet quirks for the LG-VL600 4G modem
This adds a driver for the CDC Ethernet part of this modem.  The
device's ID is blacklisted in cdc_ether.c and is white-listed in
this new driver because of the quirks needed to make it useful.
The modem's firmware exposes a CDC ACM port for modem control and a
CDC Ethernet port for network data.  The descriptors look fine but
both ports actually are some sort of multiplexers requiring non-
standard headers added/removed from every packet or they get
ignored.  All information is based on a usb traffic log from a
Windows machine.

On the Verizon 4G network I've seen speeds up to 1.1MB/s so far with
this driver, a speed-o-meter site reports 16.2Mbps/10.5Mbps.
Userspace scripts are required to talk to the CDC ACM port.

Thomas Gleixner 9ad198cba2 gpio: ab8500: Mark broken
This driver is broken in several aspects.

 1) old style irq_chip functions. Sigh

 2) Abuse of the unlock callback. That's not supposed to be a state
    machine for evrything and some more.

Anithra P Janakiraman 7fff4beb31 watchdog: softdog.c: enhancement to optionally invoke panic instead of reboot on timer expiry
This is needed for determining the reason for failure when a softdog
timeout occurs.

We use softdog to watch for critical application failures and at the
minimum a snapshot of the system would help to determine the cause.  In
such a scenario the application could fail but there isn't a softlockup as
such, hence the detect softlockup feature does not help.

The patch adds a module parameter soft_panic which when set to 1 causes
softdog to invoke panic instead of reboot when the softdog timer expires. 
By invoking panic we execute kdump if it is configured and the vmcore
generated by kdump should provide atleast a minimal idea of the reason for
failure.

WARNING: drivers/watchdog/nv_tco.o(.devinit.text+0x16): Section mismatch in reference from the function nv_tco_init() to the function .init.text:nv_tco_getdevice()
The function __devinit nv_tco_init() references

We should check if we can use that reading out. BIOS could just program wrong address there.

Anton Blanchard c211c96989 cxgb3: Apply interrupt coalescing settings to all queues
While testing the performance of different receive interrupt
coalescing settings on a single stream TCP benchmark, I noticed two
very different results. With rx-usecs=50, most of the time a
connection would hit 8280 Mbps but once in a while it would hit
9330 Mbps.

It turns out we are only applying the interrupt coalescing settings
to the first queue and whenever the rx hash would direct us onto
that queue we ran faster.

With this patch applied and rx-usecs=50, I get 9330 Mbps
consistently.

We incorrectly returned -EINVAL when none of the devices in the array
had an integrity profile.  This in turn prevented mdadm from starting
