f6271b4fb1 ab8500_btemp: Detect battery type in workqueue
Detect battery type in work queue instead of probe.

This reduces the system boot time with 1.5s.

e32ad07cea ab8500_fg: Don't clear the CCMuxOffset bit
The CCMuxOffset bit is not kept set. This will force the
columb counter of the AB8500 to use the measure offset
calibration. This should increase the accuracy of the fuel
gauge.

f8e96dff24 ab8500_charger: Charger current step-up/down
There is no state machine in the AB to step up/down the charger
current to avoid dips and spikes on VBUS and VBAT when charging
is started. Instead this is implemented in SW.

Pull networking fixes from David Miller:
 "Bug fixes galore, mostly in drivers as is often the case:

  1) USB gadget and cdc_eem drivers need adjustments to their frame size
     lengths in order to handle VLANs correctly.  From Ian Coolidge.

  2) TIPC and several network drivers erroneously call tasklet_disable
     before tasklet_kill, fix from Xiaotian Feng.

  3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
     fix from Cyril Brulebois.

  4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
     Nathan Walp.

  5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
     zero.  From John Fastabend.

  6) Fix smsc95xx tx checksum offload on big-endian, from Steve
     Glendinning.

  7) __inet_diag_dump() needs to repsect and report the error value
     returned from inet_diag_lock_handler() rather than ignore it.
     Otherwise if an inet diag handler is not available for a particular
     protocol, we essentially report success instead of giving an error
     indication.  Fix from Cyrill Gorcunov.

  8) When the QFQ packet scheduler sees TSO/GSO packets it does not
     handle things properly, and in fact ends up corrupting it's
     datastructures as well as mis-schedule packets.  Fix from Paolo
     Valente.

  9) Fix oopser in skb_loop_sk(), from Eric Leblond.

  10) CXGB4 passes partially uninitialized datastructures in to FW
      commands, fix from Vipul Pandya.

  11) When we send unsolicited ipv6 neighbour advertisements, we should
      send them to the link-local allnodes multicast address, as per
      RFC4861.  Fix from Hannes Frederic Sowa.

  12) There is some kind of bug in the usbnet's kevent deferral
      mechanism, but more immediately when it triggers an uncontrolled
      stream of kernel messages spam the log.  Rate limit the error log
      message triggered when this problem occurs, as sending thousands
      of error messages into the kernel log doesn't help matters at all,
      and in fact makes further diagnosis more difficult.

      From Steve Glendinning.

  13) Fix gianfar restore from hibernation, from Wang Dongsheng.

  14) The netlink message attribute sizes are wrong in the ipv6 GRE
      driver, it was using the size of ipv4 addresses instead of ipv6
      ones :-) Fix from Nicolas Dichtel."

193d2aadc0 sparc: Support atomic64_dec_if_positive properly.
Sparc32 already supported it, as a consequence of using the
generic atomic64 implementation.  And the sparc64 implementation
is rather trivial.

This allows us to set ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE for all
of sparc, and avoid the annoying warning from lib/atomic64_test.c

0bce04be44 of/address: sparc: Declare of_address_to_resource() as an extern function for sparc again
This bug-fix makes sure that of_address_to_resource is defined extern for sparc
so that the sparc-specific implementation of of_address_to_resource() is once
again used when including include/linux/of_address.h in a sparc context. A
number of drivers in mainline relies on this function working for sparc.

The bug was introduced in a850a75544, "of/address:
add empty static inlines for !CONFIG_OF". Contrary to that commit title, the
static inlines are added for !CONFIG_OF_ADDRESS, and CONFIG_OF_ADDRESS is never
defined for sparc. This is good behavior for the other functions in
include/linux/of_address.h, as the extern functions defined in
drivers/of/address.c only gets linked when OF_ADDRESS is configured. However,
for of_address_to_resource there exists a sparc-specific implementation in
arch/sparc/arch/sparc/kernel/of_device_common.c

5cf8f7db82 sparc: Add sparc support for platform_get_irq()
This adds sparc support for platform_get_irq that in the normal case use
platform_get_resource() to get an irq. This standard approach fails for sparc as
there are no resources of type IORESOURCE_IRQ for irqs for sparc.

Cross platform drivers can then use this standard platform function and work on
sparc instead of having to have a special case for sparc.

103cdd1d59 gianfar: ethernet vanishes after restoring from hibernation
If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.

For example:

	~# ifconfig eth0 down
	~# echo disk > /sys/power/state

	  <trigger a restore from hibernation>

	~# ifconfig eth0 up
	SIOCSIFFLAGS: No such device

This happens because the restore function bails out early upon
finding devices that were not up at hibernation.  In doing so,
it never gets to the netif_device_attach call at the end of
the restore function.  Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

9532021da6 usbnet: ratelimit kevent may have been dropped warnings
when something goes wrong, a flood of these messages can be
generated by usbnet (thousands per second).  This doesn't
generally *help* the condition so this patch ratelimits the
rate of their generation.

There's an underlying problem in usbnet's kevent deferral
mechanism which needs fixing, specifically that events *can*
get dropped and not handled.  This patch doesn't address this,
but just mitigates fallout caused by the current implemention.
