This patch adds sysfs node which can be used to get information of frequency
transition. It represents transition table which contains total number of transition of
each freqeuncy state and time spent. It is inspired CPUFREQ's status driver.Signed-off-by: Jonghwa Lee

devfreq governors such as ondemand are controlled by a min and
max frequency, while governors like userspace governor allow us
to set a specific frequency.
However, for the same specific device, depending on the SoC, the
available frequencies can vary.So expose the available frequencies as a snapshot over sysfs to
allow informed decisions.This was inspired by cpufreq framework's equivalent for similar
usage sysfs node: scaling_available_frequencies.Cc: Rajagopal Venkat

Add devfreq suspend/resume apis for devfreq users. This patch
supports suspend and resume of devfreq load monitoring, required
for devices which can idle.Signed-off-by: Rajagopal Venkat
Acked-by: MyungJoo Ham
Signed-off-by: Rafael J. Wysocki -
Prepare devfreq core framework to support devices which
can idle. When device idleness is detected perhaps through
runtime-pm, need some mechanism to suspend devfreq load
monitoring and resume back when device is online. Present
code continues monitoring unless device is removed from
devfreq core.This patch introduces following design changes,
- use per device work instead of global work to monitor device
load. This enables suspend/resume of device devfreq and
reduces monitoring code complexity.
- decouple delayed work based load monitoring logic from core
by introducing helpers functions to be used by governors. This
provides flexibility for governors either to use delayed work
based monitoring functions or to implement their own mechanism.
- devfreq core interacts with governors via events to perform
specific actions. These events include start/stop devfreq.
This sets ground for adding suspend/resume events.The devfreq apis are not modified and are kept intact.

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."* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:

2) Make the montgomery multiple/square and mpmul instructions actually

userspace with a way to use a 64-bit stack when it needs to.3) Our sparc64 atomic backoffs don't yield cpu strands properly on
Niagara chips. Use pause instruction when available to achieve
this, otherwise use a benign instruction we know blocks the strand
for some time.4) Wire up kcmp
5) Fix the build of various drivers by removing the unnecessary

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 a850a7554442f08d3e910c6eeb4ee216868dda1e, "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.cSolution suggested by: Sam Ravnborg

This adds sparc support for platform_get_irq that in the normal case use

sparc instead of having to have a special case for sparc.Signed-off-by: Andreas Larsson

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~# ifconfig eth0 up
SIOCSIFFLAGS: No such deviceThis 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.Cc: Claudiu Manoil

when something goes wrong, a flood of these messages can be

generally *help* the condition so this patch ratelimits the
rate of their generation.There's an underlying problem in usbnet's kevent deferral
