jmp/call can kill the application"), we queued these fixes via the
development tree, as a special exception.
- more fuzzer motivated race fixes and related refactoring and
robustization.
- allow PMU drivers to be built as modules. (No actual module yet,
because the x86 Intel uncore module wasn't ready in time for this)"

The bulk of the changes for this release are a few new drivers however
there are a couple of noticable core changes and the usual stream of
cleanups and fixes:
- Move disable of unused regulators later in init so it comes after
deferred probe has iterated making startup smoother.
- Fixes reference counting of the DT nodes for constraints from Charles
Keepax. This has little practical impact since all real users of
the regulator bindings use FDT which doesn't need the reference
counting.
- Lots of cleanups, especially to the Samsung drivers.
- Support for Linear Technologies LTC3589, Texas Instruments TPS658640
and X-Powers AXP20x.

on improving drivers (including taking advantage of some of the recent
framework updates):
- DMA support for the rspi driver providing a nice performance boost.
- Performance improvement for the SIRF controller in PIO mode.
- New support for the Cadence SPI IP and for pxa2xx on BayTrail.

development 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.
- Support for the Freescale i.MX6 SoloX SoC variant.
- Massive improvements in the Allwinner sunxi driver from
Boris Brezillon, Maxime Ripard and Chen-Yu Tsai.
- Renesas PFC updates from Laurent Pinchart, Kuninori
Morimoto, Wolfram Sang and Magnus Damm.
- Cleanups and refactorings of the nVidia Tegra driver from
Stepgen Warren.
- The Exynos driver now supports the Exynos3250 SoC.
- Intel BayTrail updates from Jin Yao, Mika Westerberg.
- The MVEBU driver now supports the Orion5x SoC
variants, which is part of the effort of getting rid of
the old Marvell kludges in arch/arm/mach-orion5x
- Rockchip driver updates from Heiko Stuebner.
- A ton of cleanups and janitorial patches from Axel Lin.
- Some minor fixes and improvements here and there.

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.
- support for the Freescale i.MX6 SoloX SoC variant.
- massive improvements in the Allwinner sunxi driver from Boris
Brezillon, Maxime Ripard and Chen-Yu Tsai.
- Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto,
Wolfram Sang and Magnus Damm.
- Cleanups and refactorings of the nVidia Tegra driver from Stepgen
Warren.
- the Exynos driver now supports the Exynos3250 SoC.
- Intel BayTrail updates from Jin Yao, Mika Westerberg.
- the MVEBU driver now supports the Orion5x SoC variants, which is
part of the effort of getting rid of the old Marvell kludges in
arch/arm/mach-orion5x
- Rockchip driver updates from Heiko Stuebner.
- a ton of cleanups and janitorial patches from Axel Lin.
- some minor fixes and improvements here and there"

"The biggest change in this patchset is conversion from the bootmem
bitmaps to the memblock code. This conversion requires two common
code patches to introduce the 'physmem' memblock list.
We experimented with ticket spinlocks but in the end decided against
them as they perform poorly on virtualized systems. But the spinlock
cleanup and some small improvements are included.
The uaccess code got another optimization, the get_user/put_user calls
are now inline again for kernel compiles targeted at z10 or newer
machines. This makes the text segment shorter and the code gets a
little bit faster.
And as always some bug fixes"

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

ASoC: Final updates for v3.16
A few more updates from the last week of development, nothing too
exciting. Highlights include:
- GPIO descriptor support for jacks
- More updates and fixes to the Freescale SSI, Intel and rsnd drivers.
- New drivers for Analog Devices ADAU1361, ADAU1381, ADAU1761 and

This is the same change as commit fb6b8e7144 "ASoC: tegra: free jack

machine drivers where code inspection indicates the same problem exists.
That commit's description is:
==========
snd_soc_jack_add_gpios() schedules a work queue item to poll the GPIO to
generate an initial jack status report. If sound card initialization
fails, that work item needs to be cancelled, so it doesn't run after the
card has been freed. Specifically, freeing the card calls
snd_jack_dev_free() which calls snd_jack_dev_disconnect() which sets
jack->input_dev = NULL, and input_dev is used by snd_jack_report(), which
is called from the work queue item.
snd_soc_jack_free_gpios() cancels the work item. The Tegra ASoC machine
drivers do call this function in the platform driver remove() callback.
However, this happens after the sound card is freed, at least when the
card is freed due to errors late during snd_soc_instantiate_card(). This
leaves a window where the work item can execute after the card is freed.
In next-20140522, sound card initialization does fail for unrelated
reasons, and hits the problem described above.
To solve this, fix the Tegra ASoC machine drivers to clean up the Jack
GPIOs during the snd_soc_card's .remove() callback, which is executed
before the overall card object is freed. also, guard the cleanup call
based on whether we actually setup up the GPIOs in the first place.
Ideally, we'd do the cleanup in a struct snd_soc_dai_link .fini/remove
function to match where the GPIOs get set up. However, there is no such
callback.

Note that I have not even compile-tested this in most cases, since most
of the drivers rely on specific mach-* support I don't have enabled, and
don't support COMPILE_TEST. Testing by the relevant board maintainers
would be useful.
