e5c4ecdc55 USB driver patches for 3.16-rc1 
Here is the big USB driver pull request for 3.16-rc1.
 
 Nothing huge here, but lots of little things in the USB core, and in
 lots of drivers.  Hopefully the USB power management will be work better
 now that it has been reworked to do per-port power control dynamically.
 There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
 is finally gone now that everything has been converted over to the
 dynamic debug inteface, the last hold-out drivers were cleaned up and
 the config option removed.  There were also other minor things all
 through the drivers/usb/ tree, the shortlog shows this pretty well.
 
 All have been in linux-next, including the very last patch, which came
 from linux-next to fix a build issue on some platforms.

5142c33ed8 Staging driver patches for 3.16-rc1 
Here is the big staging driver pull request for 3.16-rc1.
 
 Lots of stuff here, tons of cleanup patches, a few new drivers, and some
 removed as well, but I think we are still adding a few thousand more
 lines than we remove, due to the new drivers being bigger than the ones
 deleted.
 
 One notible bit of work did stand out, Jes Sorensen has gone on a tear,
 fixing up a wireless driver to be "more sane" than it originally was
 from the vendor, with over 500 patches merged here.  Good stuff, and a
 number of users laptops are better off for it.

a727eaf64f ARM: SoC driver changes 
SoC-near driver changes that we're merging through our tree. Mostly
 because they depend on other changes we have staged, but in some cases
 because the driver maintainers preferred that we did it this way.
 
 This contains a largeish cleanup series of the omap_l3_noc bus driver,
 cpuidle rework for Exynos, some reset driver conversions and a long
 branch of TI EDMA fixes and cleanups, with more to come next release.
 
 The TI EDMA cleanups is a shared branch with the dmaengine tree, with
 a handful of Davinci-specific fixes on top.
 
 After discussion at last year's KS (and some more on the mailing lists),
 we are here adding a drivers/soc directory. The purpose of this is
 to keep per-vendor shared code that's needed by different drivers but
 that doesn't fit into the MFD (nor drivers/platform) model. We expect
 to keep merging contents for this hierarchy through arm-soc so we can
 keep an eye on what the vendors keep adding here and not making it a
 free-for-all to shove in crazy stuff.

 - Qualcomm APQ8064 and APQ8084 SoCs and eval boards
 - Nvidia Jetson TK1 development board (Tegra T124-based)

c67d9ce166 ARM: SoC board support updates for 3.16 
The bulk of this branch is updates for Renesas Shmobile. They are still
 doing some enablement for classic boards first, and then come up with DT
 bindings when they've had a chance to learn more about the hardware. Not
 necessarily a bad way to go about it, and they're looking at moving some
 of the temporary board code resulting from it to drivers/staging instead
 to avoid the churn here.
 
 As a result of the shmobile clock cleanups, we end up merging quite a
 bit of SH code here as well. We ended up merging it here instead of in
 the cleanup branch due to the other board changes depending on it.

825f4e0271 ARM: SoC updates for 3.16 (part 1) 
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

Pull block core updates from Jens Axboe:
 "It's a big(ish) round this time, lots of development effort has gone
  into blk-mq in the last 3 months.  Generally we're heading to where
  3.16 will be a feature complete and performant blk-mq.  scsi-mq is
  progressing nicely and will hopefully be in 3.17.  A nvme port is in
  progress, and the Micron pci-e flash driver, mtip32xx, is converted
  and will be sent in with the driver pull request for 3.16.

  This pull request contains:

   - Lots of prep and support patches for scsi-mq have been integrated.
     All from Christoph.

   - API and code cleanups for blk-mq from Christoph.

   - Lots of good corner case and error handling cleanup fixes for
     blk-mq from Ming Lei.

   - A flew of blk-mq updates from me:

     * Provide strict mappings so that the driver can rely on the CPU
       to queue mapping.  This enables optimizations in the driver.

     * Provided a bitmap tagging instead of percpu_ida, which never
       really worked well for blk-mq.  percpu_ida relies on the fact
       that we have a lot more tags available than we really need, it
       fails miserably for cases where we exhaust (or are close to
       exhausting) the tag space.

     * Provide sane support for shared tag maps, as utilized by scsi-mq

     * Various fixes for IO timeouts.

     * API cleanups, and lots of perf tweaks and optimizations.

   - Remove 'buffer' from struct request.  This is ancient code, from
     when requests were always virtually mapped.  Kill it, to reclaim
     some space in struct request.  From me.

   - Remove 'magic' from blk_plug.  Since we store these on the stack
     and since we've never caught any actual bugs with this, lets just
     get rid of it.  From me.

   - Only call part_in_flight() once for IO completion, as includes two
     atomic reads.  Hopefully we'll get a better implementation soon, as
     the part IO stats are now one of the more expensive parts of doing
     IO on blk-mq.  From me.

   - File migration of block code from {mm,fs}/ to block/.  This
     includes bio.c, bio-integrity.c, bounce.c, and ioprio.c.  From me,
     from a discussion on lkml.

  That should describe the meat of the pull request.  Also has various
  little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
  Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
  Bradshaw"

80fb974798 This is the bulk of GPIO changes for the v3.16 series: 
- We are finalizing and fixing up the gpiochip irqchip helpers
   bringing a helpful irqchip implementation into the gpiolib
   core and avoiding duplicate code and, more importantly,
   duplicate bug fixes:
 
   - Support for using the helpers with threaded interrupt
     handlers as used on sleeping GPIO-irqchips
 
   - Do not set up hardware triggers for edges or levels if
     the default IRQ type is IRQ_TYPE_NONE - some drivers
     would exploit the fact that you could get default
     initialization of the IRQ type from the core at probe()
     but if no default type is set up from the helper, we
     should not call the driver to configure anything. Wait
     until a consumer requests the interrupt instead.
 
   - Make the irqchip helpers put the GPIO irqs into their
     own lock class. The GPIO irqchips can often emit
     (harmless, but annoying) lockdep warnings about recursions
     when they are in fact just cascaded IRQs. By putting
     them into their own lock class we help the lockdep core
     to keep track of things.
 
   - Switch the tc3589x GPIO expanders to use the irqchip
     helpers
 
   - Switch the OMAP GPIO driver to use the irqchip helpers
 
   - Add some documentation for the irqchip helpers
 
   - select IRQ_DOMAIN when using the helpers since some
     platforms may not be using this by default and it's a
     strict dependency.
 
 - Continued GPIO descriptor refactoring:
 
   - Remove the one instance of gpio_to_desc() from the
     device tree code, making the OF GPIO code use GPIO
     descriptors only.
 
   - Introduce gpiod_get_optional() and
     gpiod_get_optional_index() akin to the similar
     regulator functions for cases where the use of GPIO
     is optional and not strictly required.
 
   - Make of_get_named_gpiod_flags() private - we do not
     want to unnecessarily expose APIs to drivers that
     make the gpiolib harder than necessary to maintain
     and refactor. Privatize this function.
 
 - Support "-gpio" suffix for the OF GPIO retrieveal path.
   We used to look for "foo-gpios" or just "gpios" in device
   tree nodes, but it turns out that some drivers with a
   single GPIO line will just state "foo-gpio" (singularis).
   Sigh. Support this with a fallback looking for it, as
   this simplifies driver code and handles it in core code.
 
 - Switch the ACPI GPIO core to fetch GPIOs with the
   *_cansleep function variants as the GPIO operation
   region handler can sleep, and shall be able to handle
   gpiochips that sleep.
 
 - Tons of cleanups and janitorial work from Jingoo Han,
   Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
   Notably Jingoo cut off a ton of pointless OOM messages.
 
 - Incremental development and fixes for various drivers,
   nothing really special here.

Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v3.16 series.

  There is a lot of action in the GPIO subsystem doing refactorings and
  cleanups, almost as many deletions as insertions and minor feature
  growth and no new drivers this time.  Which is actually pretty nice.
  Some GPIO-related stuff will come in through the pin control tree as
  well.

  Details:

   - We are finalizing and fixing up the gpiochip irqchip helpers
     bringing a helpful irqchip implementation into the gpiolib core and
     avoiding duplicate code and, more importantly, duplicate bug fixes:

Add support for a generic PCI host controller, such as a
firmware-initialised device with static windows or an emulation by
something such as kvmtool.

The controller itself has no configuration registers and has its address
spaces described entirely by the device-tree (using the bindings from
ePAPR).  Both CAM and ECAM are supported for Config Space accesses.

Add corresponding documentation for the DT binding.

2fe2023adf firewire: revert to 4 GB RDMA, fix protocols using Memory Space 
Undo a feature introduced in v3.14 by commit fcd46b3442
"firewire: Enable remote DMA above 4 GB".  That change raised the
minimum address at which protocol drivers and user programs can register
for request reception from 0x0001'0000'0000 to 0x8000'0000'0000.
It turned out that at least one vendor-specific protocol exists which
uses lower addresses:  https://bugzilla.kernel.org/show_bug.cgi?id=76921

For the time being, revert most of commit fcd46b3442 so that affected
protocols work like with kernel v3.13 and before.  Just keep the valid
documentation parts from the regressing commit, and the ability to
identify controllers which could be programmed to accept >32 bit
physical DMA addresses.  The rest of fcd46b3442 should probably be
brought back as an optional instead of default feature.

782a985d7a PCI: Introduce new device binding path using pci_dev.driver_override 
The driver_override field allows us to specify the driver for a device
rather than relying on the driver to provide a positive match of the
device.  This shortcuts the existing process of looking up the vendor and
device ID, adding them to the driver new_id, binding the device, then
removing the ID, but it also provides a couple advantages.

First, the above existing process allows the driver to bind to any device
matching the new_id for the window where it's enabled.  This is often not
desired, such as the case of trying to bind a single device to a meta
driver like pci-stub or vfio-pci.  Using driver_override we can do this
deterministically using:

  echo pci-stub > /sys/bus/pci/devices/0000:03:00.0/driver_override
  echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind
  echo 0000:03:00.0 > /sys/bus/pci/drivers_probe

Previously we could not invoke drivers_probe after adding a device to
new_id for a driver as we get non-deterministic behavior whether the driver
we intend or the standard driver will claim the device.  Now it becomes a
deterministic process, only the driver matching driver_override will probe
the device.

To return the device to the standard driver, we simply clear the
driver_override and reprobe the device:

  echo > /sys/bus/pci/devices/0000:03:00.0/driver_override
  echo 0000:03:00.0 > /sys/bus/pci/devices/0000:03:00.0/driver/unbind
  echo 0000:03:00.0 > /sys/bus/pci/drivers_probe

Another advantage to this approach is that we can specify a driver override
to force a specific binding or prevent any binding.  For instance when an
IOMMU group is exposed to userspace through VFIO we require that all
devices within that group are owned by VFIO.  However, devices can be
hot-added into an IOMMU group, in which case we want to prevent the device
from binding to any driver (override driver = "none") or perhaps have it
automatically bind to vfio-pci.  With driver_override it's a simple matter
for this field to be set internally when the device is first discovered to
prevent driver matches.

06aa82e498 serial: uart: add hw flow control support configuration 
8250 uart driver currently supports only software assisted hw flow
control. The software assisted hw flow control maintains a hw_stopped
flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

e0b0baadb7 tty/serial: at91: use mctrl_gpio helpers 
On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.

Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.

This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

7913ad1ad8 m68k: Multi-platform EARLY_PRINTK 
Make the boot console available to more m68k platforms by leveraging
the head.S debug console.

The boot console is enabled by the "earlyprintk" command line argument
which is how most other architectures do this.

This is a change of behaviour for the Mac but does not negatively impact
the common use-case which is not debugging.

This is also a change of behaviour for other platforms because it means
the serial port stays quiet when CONFIG_EARLY_PRINTK is not enabled. This
is also an improvement for the common use-case.

8a0427d192 w1: optional bundling of netlink kernel replies 
Applications can submit a set of commands in one packet to the kernel,
and in some cases it is required such as reading the temperature
sensor results.  This adds an option W1_CN_BUNDLE to the flags of
cn_msg to request the kernel to reply in one packet for efficiency.

The cn_msg flags now check for unknown flag values and return an error
if one is seen.  See "Proper handling of unknown flags in system
calls" http://lwn.net/Articles/588444/

This corrects the ack values returned as per the protocol standard,
namely the original ack for status messages and seq + 1 for all others
such as the data returned from a read.

Some of the common variable names have been standardized as follows.
struct cn_msg *cn
struct w1_netlink_msg *msg
struct w1_netlink_cmd *cmd
struct w1_master *dev

When an argument and a function scope variable would collide, add req_
to the argument.
