cycle:
- Antoine Tenart made the get_group_pins() vtable entry optional.
- Antoine also provides an entirely new driver for the Marvell Berlin
SoC. This is unrelated to the existing MVEBU hardware driver and
warrants its own separate driver.
- reflected from the GPIO subsystem there is a number of refactorings
to make pin control drivers with gpiochips use the new gpiolib
irqchip helpers. The following drivers were converted to use the
new infrastructure:
* ST Microelectronics STiH416 and friends
* The Atmel AT91
* The CSR SiRF (Prima2)
* The Qualcomm MSM series
- massive improvements in the Qualcomm MSM driver from Bjorn
Andersson, Andy Gross and Kumar Gala. Among those new support for
the IPQ8064 and MSM8x74 SoC variants.

"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"

"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

Merge tag 'gpio-v3.16-1' of git://git./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:
* 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"

ARM: exynos: don't run exynos4 l2x0 setup on other platforms
This was caught by a panic on Broadcom mobile platforms.
Note that this code is all going away with the pending l2x0 cleanup
series from Russell, but we need this here until that's landed so we
can enable exynos multiplatform.

dcache: add missing lockdep annotation
lock_parent() very much on purpose does nested locking of dentries, and
is careful to maintain the right order (lock parent first). But because
it didn't annotate the nested locking order, lockdep thought it might be
a deadlock on d_lock, and complained.
Add the proper annotation for the inner locking of the child dentry to
make lockdep happy.

blk-mq: push IPI or local end_io decision to __blk_mq_complete_request()
We have callers outside of the blk-mq proper (like timeouts) that
want to call __blk_mq_complete_request(), so rename the function
and put the decision code for whether to use ->softirq_done_fn
or blk_mq_endio() into __blk_mq_complete_request().
This also makes the interface more logical again.
blk_mq_complete_request() attempts to atomically mark the request
completed, and calls __blk_mq_complete_request() if successful.
__blk_mq_complete_request() then just ends the request.

drm/crtc-helper: explicit DPMS on after modeset
which was merged long ago and actually part of 3.14.
Digging deeper I've noticed (again) that the call to
drm_helper_resume_force_mode in the radeon resume handlers was a no-op
previously because everything gets shut down on suspend. radeon does
this with explicit calls to drm_helper_connector_dpms with DPMS_OFF.
But with 177c we now force the dpms state to ON, so suddenly
resume_force_mode actually forced the crtcs back on.
This is the intention of the change after all, the problem is that
radeon resumes the fbdev console layer _before_ restoring the display,
through calling fb_set_suspend. And fbcon does an immediate ->set_par,
which in turn causes the same forced mode restore to happen.
Two concurrent modeset operations didn't lead to happiness. Fix this
by delaying the fbcon resume until the end of the readeon resum
functions.
v2: Fix up a bit of the spelling fail.

x86_64: expand kernel stack to 16K
While I play inhouse patches with much memory pressure on qemu-kvm,
3.14 kernel was randomly crashed. The reason was kernel stack overflow.
When I investigated the problem, the callstack was a little bit deeper
by involve with reclaim functions but not direct reclaim path.
I tried to diet stack size of some functions related with alloc/reclaim
so did a hundred of byte but overflow was't disappeard so that I encounter
overflow by another deeper callstack on reclaim/allocator path.
Of course, we might sweep every sites we have found for reducing
stack usage but I'm not sure how long it saves the world(surely,
lots of developer start to add nice features which will use stack
agains) and if we consider another more complex feature in I/O layer
and/or reclaim path, it might be better to increase stack size(
meanwhile, stack usage on 64bit machine was doubled compared to 32bit
while it have sticked to 8K. Hmm, it's not a fair to me and arm64
already expaned to 16K. )
So, my stupid idea is just let's expand stack size and keep an eye
toward stack consumption on each kernel functions via stacktrace of ftrace.
For example, we can have a bar like that each funcion shouldn't exceed 200K
and emit the warning when some function consumes more in runtime.
Of course, it could make false positive but at least, it could make a
chance to think over it.
I guess this topic was discussed several time so there might be
strong reason not to increase kernel stack size on x86_64, for me not
knowing so Ccing x86_64 maintainers, other MM guys and virtio
maintainers.
Here's an example call trace using up the kernel stack:

[ Note: the problem is exacerbated by certain gcc versions that seem to
generate much bigger stack frames due to apparently bad coalescing of
temporaries and generating too many spills. Rusty saw gcc-4.6.4 using
35% more stack on the virtio path than 4.8.2 does, for example.
Minchan not only uses such a bad gcc version (4.6.3 in his case), but
some of the stack use is due to debugging (CONFIG_DEBUG_PAGEALLOC is
what causes that kernel_map_pages() frame, for example). But we're
clearly getting too close.
The VM code also seems to have excessive stack frames partly for the
same compiler reason, triggered by excessive inlining and lots of
function arguments.
We need to improve on our stack use, but in the meantime let's do this
simple stack increase too. Unlike most earlier reports, there is
nothing simple that stands out as being really horribly wrong here,
apart from the fact that the stack frames are just bigger than they
should need to be. - Linus ]

cpufreq: exynos: Fix driver compilation with ARCH_MULTIPLATFORM
Currently Exynos cpufreq drivers rely on globally mapped
clock controller registers to configure frequency of CPU
cores. This is obviously wrong and will be removed in near
future, but to enable support for multi-platform builds
without introducing a regression it needs to be worked
around.
This patch hacks the code to look for clock controller node
in device tree and map its registers using of_iomap(),
instead of relying on global mapping, so dependencies on
platform headers are removed and the driver can compile
again with multiplatform support.
