* add 'struct lm3530_pwm_data' in the platform data
The pwm data is the platform specific functions which generate the pwm.
The pwm data is only valid when brightness is pwm input mode.
Functions should be implemented by the pwm driver.
pwm_set_intensity() : set duty of pwm.
pwm_get_intensity() : get current the brightness.
* brightness control by pwm
If the control mode is pwm, then brightness is changed by the duty of
pwm=. So pwm platform function should be called in lm3530_brightness_set().
* do not update brightness register when pwm input mode
In pwm input mode, brightness register is not used.
If any value is updated in this register, then the led will be off.
* when input mode is changed, set duty of pwm to 0 if unnecessary.

On initializing registers, maximum initial brightness is limited to

Division-by-two is removed on updating the brightness. This arithmetic is

The lp5521 has autonomous operation mode without external control.
Using lp5521_platform_data, various led patterns can be configurable.
For supporting this feature, new functions and device attribute are
added.
Structure of lp5521_led_pattern: 3 channels are supported - red, green
and blue. Pattern(s) of each channel and numbers of pattern(s) are
defined in the pla= tform data. Pattern data are hexa codes which
include pattern commands such like set pwm, wait, ramp up/down, branch
and so on.
Pattern mode functions:
* lp5521_clear_program_memory
Before running new led pattern, program memory should be cleared.
* lp5521_write_program_memory
Pattern data updated in the program memory via the i2c.
* lp5521_get_pattern
Get pattern from predefined in the platform data.
* lp5521_run_led_pattern
Stop current pattern or run new pattern.
Transition time is required between different operation mode.
Device attribute - 'led_pattern': To load specific led pattern, new device
attribute is added.
When the lp5521 driver is unloaded, stop current led pattern mode.
Documentation updated : description about how to define the led patterns
and example.

It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave. Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm

In the statement
j->caplist[j->caps].handle = j->caps++;
there is no sequence point between the usage of j->caps on the LHS of
the assignment and the incrementation on its RHS. So it's not defined
in Standard C if j->caps is already incremented when used on the LHS
even though the postfix ++ operator is used. To properly fix that the
incrementation has to be done in a separate expression.

6) Fix races in TG3 driver ring refilling, from Michael Chan.
7) We have callbacks for IPSEC replay notifiers, but some call sites

implementations directly. Oops. Fix from Steffen Klassert.
8) Fix IP address validation properly in the bonding driver, the
previous fix only works with netlink where the subnet mask and IP
address are changed in one atomic operation. When 'ifconfig' ioctls
are used the IP address and the subnet mask are changed in two
distinct operations. Fix from Andy Gospodarek.

seeing a trickle of new features coming in they're getting much smaller
than they were. It's also nice to have some features which support
other subsystems building infrastructure on top of regmap. Highlights
include:
- Support for padding between the register and the value when
interacting with the device, sometimes needed for fast interfaces.
- Support for applying register updates to the device when restoring the
register state. This is intended to be used to apply updates supplied by
manufacturers for tuning the performance of the device (many of which
are to undocumented registers which aren't otherwise covered).
- Support for multi-register operations on cached registers.
- Support for syncing only part of the register cache.
- Stubs and parameter query functions intended to make it easier for other
subsystems to build infrastructure on top of the regmap API.
plus a few driver updates making use of the new features which it was
easier to merge via this tree.

The following patch aimed to resolve an issue where secondary, tertiary,
etc. addresses added to bond interfaces could overwrite the
bond->master_ip and vlan_ip values.

bonding: only use primary address for ARP
That patch was good because it prevented bonds using ARP monitoring from
sending frames with an invalid source IP address. Unfortunately, it
didn't always work as expected.
When using an ioctl (like ifconfig does) to set the IP address and
netmask, 2 separate ioctls are actually called to set the IP and netmask
if the mask chosen doesn't match the standard mask for that class of
address. The first ioctl did not have a mask that matched the one in
the primary address and would still cause the device address to be
overwritten. The second ioctl that was called to set the mask would
then detect as secondary and ignored, but the damage was already done.
This was not an issue when using an application that used netlink
sockets as the setting of IP and netmask came down at once. The
inconsistent behavior between those two interfaces was something that
needed to be resolved.
While I was thinking about how I wanted to resolve this, Ralf Zeidler
came with a patch that resolved this on a RHEL kernel by keeping a full
shadow of the entries in dev->ifa_list for the bonding device and vlan
devices in the bonding driver. I didn't like the duplication of the
list as I want to see the 'bonding' struct and code shrink rather than
grow, but liked the general idea.
As the Subject indicates this patch drops the master_ip and vlan_ip
elements from the 'bonding' and 'vlan_entry' structs, respectively.
This can be done because a device's address-list is now traversed to
determine the optimal source IP address for ARP requests and for checks
to see if the bonding device has a particular IP address. This code
could have all be contained inside the bonding driver, but it made more
sense to me to EXPORT and call inet_confirm_addr since it did exactly
what was needed.
I tested this and a backported patch and everything works as expected.
Ralf also helped with verification of the backported patch.
Thanks to Ralf for all his help on this.
v2: Whitespace and organizational changes based on suggestions from Jay

Pull s390 patches from Martin Schwidefsky:
"The biggest patch is the rework of the smp code, something I wanted to
do for some time. There are some patches for our various dump methods
and one new thing: z/VM LGR detection. LGR stands for linux-guest-
relocation and is the guest migration feature of z/VM. For debugging
purposes we keep a log of the systems where a specific guest has lived."
Fix up trivial conflict in arch/s390/kernel/smp.c due to the scheduler
cleanup having removed some code next to removed s390 code.

URB unlinking is always racing with its completion and tx_complete
may be called before or during running usb_unlink_urb, so tx_complete
must not clear urb->dev since it will be used in unlink path,
otherwise invalid memory accesses or usb device leak may be caused
inside usb_unlink_urb.
