8934d3e4d0 usb: musb: omap2430: Don't use omap_get_control_dev()
omap_get_control_dev() is being deprecated as it doesn't support
multiple instances. As control device is present only from OMAP4
onwards which supports DT only, we use phandles to get the
reference to the control device.

Also get rid of "ti,has-mailbox" property as it is redundant and
we can determine that from whether "ctrl-module" property is present
or not. Get rid of has_mailbox from musb_hdrc_platform_data as well.

6cb9310a32 usb: phy: omap: Add new device types and remove omap_control_usb3_phy_power()
Add support for new device types and in the process rid of "ti,type"
device tree property. The correct type of device will be determined
from the compatible string instead.

Introduce a compatible string for each device type. At the moment
we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2.

Update DT binding information to reflect these changes.

Also get rid of omap_control_usb3_phy_power(). Just one function
i.e. omap_control_usb_phy_power() will now take care of all PHY types.

26c019fc85 TTY/Serial fixes for 3.12-rc3
Here are some serial at tty driver fixes for 3.12-rc3
 
 The serial driver fixes some kref leaks, documentation is moved to the proper
 places, and the tty and n_tty fixes resolve some reported regressions.  There
 is still one outstanding tty regression fix that isn't in here yet, as I want
 to test it out some more, it will be sent for 3.12-rc4 if it checks out.

ff76496347 drivers: phy: add generic PHY framework
The PHY framework provides a set of APIs for the PHY drivers to
create/destroy a PHY and APIs for the PHY users to obtain a reference to the
PHY with or without using phandle. For dt-boot, the PHY drivers should
also register *PHY provider* with the framework.

PHY drivers should create the PHY by passing id and ops like init, exit,
power_on and power_off. This framework is also pm runtime enabled.

The documentation for the generic PHY framework is added in
Documentation/phy.txt and the documentation for dt binding can be found at
Documentation/devicetree/bindings/phy/phy-bindings.txt

7eacd03810 bonding: Make alb learning packet interval configurable
running bonding in ALB mode requires that learning packets be sent periodically,
so that the switch knows where to send responding traffic.  However, depending
on switch configuration, there may not be any need to send traffic at the
default rate of 3 packets per second, which represents little more than wasted
data.  Allow the ALB learning packet interval to be made configurable via sysfs

  The biggest change is about exynos thermal driver restructure.  The
  patch set adds TMU (Thermal management Unit) driver support for
  exynos5440 platform.  There are 3 instances of the TMU controllers so
  necessary cleanup/re-structure is done to handle multiple thermal
  zone.

  The next biggest change is the introduction of the imx thermal driver.
  It adds the imx thermal support using Temperature Monitor (TEMPMON)
  block found on some Freescale i.MX SoCs.  The driver uses syscon
  regmap interface to access TEMPMON control registers and calibration
  data, and supports cpufreq as the cooling device.

  Highlights:

   - restructure exynos thermal driver.

   - introduce new imx thermal driver.

   - fix a bug in thermal core, which powers on the fans unexpectedly
     after resume from suspend"

modification, warnings like the one shown below appear in the system logs:

  /var/log/messages:Aug 22 11:09:11 kung udevd[445]: NAME="%k" \

    it from /etc/udev/rules.d/60-aoe.rules:26

Removing the term does not cause any problems with the creation of the

65aafb1e74 coredump: add new %P variable in core_pattern
Add a new %P variable to be used in core_pattern.  This variable contains
the global PID (PID in the init namespace) as %p contains the PID in the
current namespace which isn't always what we want.

The main use for this is to make it easier to handle crashes that happened
within a container.  With that new variables it's possible to have the
crashes dumped into the container or forwarded to the host with the right
PID (from the host's point of view).

666a584d3a drivers/rtc/rtc-palmas.c: support for backup battery charging
Palmas series device like TPS65913, TPS80036 supports the backup battery
for powering the RTC when no other energy source is available.

The backup battery is optional, connected to the VBACKUP pin, and can be
nonrechargeable or rechargeable.  The rechargeable battery can be charged
from the system supply using the backup battery charger.

Add support for enabling charging of this backup battery.  Also add the DT
binding document and the new properties to have this support.

d9104d1ca9 mm: track vma changes with VM_SOFTDIRTY bit
Pavel reported that in case if vma area get unmapped and then mapped (or
expanded) in-place, the soft dirty tracker won't be able to recognize this
situation since it works on pte level and ptes are get zapped on unmap,
loosing soft dirty bit of course.

So to resolve this situation we need to track actions on vma level, there
VM_SOFTDIRTY flag comes in.  When new vma area created (or old expanded)
we set this bit, and keep it here until application calls for clearing
soft dirty bit.

Thus when user space application track memory changes now it can detect if
vma area is renewed.

86cdb465cf mm: prepare to remove /proc/sys/vm/hugepages_treat_as_movable
Now hugepage migration is enabled, although restricted on pmd-based
hugepages for now (due to lack of testing.) So we should allocate
migratable hugepages from ZONE_MOVABLE if possible.

This patch makes GFP flags in hugepage allocation dependent on migration
support, not only the value of hugepages_treat_as_movable.  It provides no
change on the behavior for architectures which do not support hugepage
migration,
