The force_kill member of struct oom_control isn't needed if an order of -1
is used instead. This is the same as order == -1 in struct
compact_control which requires full memory compaction.
This patch introduces no functional change.

There are essential elements to an oom context that are passed around to
multiple functions.
Organize these elements into a new struct, struct oom_control, that
specifies the context for an oom condition.
This patch introduces no functional change.

This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.
Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram). This completes
client side changes related to genalloc updates.

Architectures which support VGA console must define screen_info
structurture from "uapi/linux/screen_info.h". Otherwise undefined
symbol error occurs. Usually it's defined in "setup.c" for each
architecture.
If an architecture does not support VGA console (ARC's case) there are 2
ways: define a dummy instance of screen_info or add a negative
dependency for VGA_CONSOLE in to prevent selecting this option.
I've implemented the second way. However the best solution is to add
HAVE_VGA_CONSOLE option for targets which support VGA console. Then
turn off VGA_CONSOLE by default and add dependency to HAVE_VGA_CONSOLE.
But right now it's better to just add a negative dependency for ARC and
then consider how to collaborate about this issue with maintainers of
other architectures.

first three sections are not present.
The current register_mem_sect_under_node() assume first section is
present, but memory block section number range [start_section_nr,
end_section_nr] would include not present section.
For arch that support vmemmap, we don't setup memmap for struct page
area within not present sections area.
So skip the pfn range that belong to absent section.

Pull sound updates from Takashi Iwai:
"There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-related
changes for a slight API additions / changes, and that's all.
Looking at the code size statistics, the most significant addition is
for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.
In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.
Other than that, USB-audio got a rewrite of runtime PM code. It was
initiated by lockdep warning, but resulted in a good cleanup in the
end.
Below are the highlights:
Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)
ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel
HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP

- dma controller in sun[457]i SoCs
- lpc18xx dmamux
- ZTE ZX296702 dma controller
- Analog Devices AXI-DMAC DMA controller
- eDMA support for dma-crossbar
- imx6sx support in imx-sdma driver

[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
handled the conflict with the new Intel integrated IDMA driver by
slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
order to keep the Intel entries together. I think it might be a good
idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
the sorting be a true sort, not this mismash.
Also, this merge disables the COMPILE_TEST for the sun4i DMA
controller, because it does not compile cleanly at all. - Linus ]

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.3 development
cycle.
Like with GPIO it's a lot of stuff. If my subsystems are any sign of
the overall tempo of the kernel v4.3 will be a gigantic diff.
[ It looks like 4.3 is calmer than 4.2 in most other subsystems, but
we'll see - Linus ]
Core changes:
- It is possible configure groups in debugfs.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data(). This series was
created by Thomas Gleixner after the problem was observed by
Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx also wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
Driver feature enhancements:
- Power management support for the SiRF SoC Atlas 7.
- Power down support for the Qualcomm driver.
- Intel Cherryview and Baytrail: switch drivers to use raw spinlocks
in IRQ handlers to play nice with the realtime patch set.
- Rework and new modes handling for Qualcomm SPMI-MPP.
- Pinconf power source config for SH PFC.
New drivers and subdrivers:
- A new driver for Conexant Digicolor CX92755.
- A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8, PH1-Pro5,
ProXtream2 and PH1-LD6b SoC pin control support.
- Reverse-egineered the S/PDIF settings for the Allwinner sun4i
driver.
- Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
- A new Freescale i.mx6ul subdriver.
Cleanup:
- Remove platform data support in a number of SH PFC subdrivers"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.3 kernel cycle.
There is quite a lot going on in the GPIO subsystem this merge window,
so the main matter is decribed below.
The hits in other subsystems when making the GPIO flags optional are
all ACKed by their respective subsystem maintainers.
Core changes:
- Root out the wrapper devm_gpiod_get() and gpiod_get() etc versions
of the descriptor calls that did not use the flags argument on the
end. This was around for too long and eventually Uwe Kleine-König
took the time to clean it out and the last users are removed along
with the macros in this tag. In several cases the use of flags
simplifies the code. For this reason we have (ACKed) patches
hitting in DRM, IIO, media, NFC, USB+PHY up until we hammer in the
nail with removing the macros.
- Add a fat document describing how much ready-made GPIO stuff we
have i the kernel to discourage people from reinventing a square
wheel in userspace, as so often happens.
- Create a separate lockdep class for each instance of a GPIO IRQ
chip instead of using one class for all chips, as the current code
will not work with systems with several GPIO chips doing lockdep
debugging.
- Protect against driver unloading also when a GPIO line is only used
as IRQ for the GPIOLIB_IRQCHIP helpers.
- If the GPIO chip has no designated owner, assign the parent device
driver owner as owner.
- Consolidation of chained IRQ handler install/remove replacing all
call sites where irq_set_handler_data() and
irq_set_chained_handler() were done in succession with a combined
call to irq_set_chained_handler_and_data().
This series was created by Thomas Gleixner after the problem was
observed by Russell King.
- Tglx also made another series of patches switching
__irq_set_handler_locked() for irq_set_handler_locked() which is
way cleaner.
- Tglx and Jiang Liu wrote a good bunch of patches to make use of
irq_desc_get_xxx() accessors and avoid looking up irq_descs from
IRQ numbers. The goal is to get rid of the irq number from the
handlers in the IRQ flow which is nice.
- Rob Herring killed off the set_irq_flags() for all GPIO drivers.
This was an ARM specific function that is replaced with the generic
irq_modify_status() where special flags are actually needed.
- When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER
if the pin controller isn't available. Pretty logical, yet needed
to be fixed.
- If a driver using GPIOLIB_IRQCHIP has its own irq_*_resources call
back, then call these instead of the defaults provided by the
GPIOLIB.
- Fix an undocumented ABI hole: named GPIOs were not properly
documented.
Driver improvements:
- Add get_direction() support to the generic GPIO driver, it's
strange that we didn't have that before.
- Make it possible to have input-only GPIO chips using the generic
GPIO driver.
- Clean out platform data support from the Emma Mobile (EM) driver
- Finegrained runtime PM support for the RCAR driver.
- Support r8a7795 (R-car H3) in the RCAR driver.
- Support interrupts on GPIOs 16 thru 31 in the DaVinci driver.
- Some consolidation and new support in the MPC8xxx driver, we now
support MPC5125.
- Preempt-RT-friendly patches: the OMAP, MPC8xxx, drivers uses raw
spinlocks making it work better with the realime patches.
- Interrupt support for the EXTRAXFS GPIO driver.
- Make the ETRAXFS GPIO driver support also ARTPEC-3.
- Interrupt and wakeup support for the BRCMSTB driver, also for
wakeup from S5 cold boot.
- Mask MXC IRQs during suspend.
- Improve OMAP2 GPIO set_debounce() to work according to spec.
- The VF610 driver handles IRQs properly.
New drivers:
- ZTE ZX GPIO driver"

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for 4.3 for MIPS. Here's the summary:
Three fixes that didn't make 4.2-stable:
- a -Os build might compile the kernel using the MIPS16 instruction
set but the R2 optimized inline functions in <uapi/asm/swab.h> are
implemented using 32-bit wide instructions which is invalid.
- a build error in pgtable-bits.h for a particular kernel
configuration.
- accessing registers of the CM GCR might have been compiled to use
64 bit accesses but these registers are onl 32 bit wide.
And also a few new bits:
- move the ATH79 GPIO driver to drivers/gpio
- the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
change ATH79 accordingly.
- fix definition of pgprot_writecombine
- add an implementation of dma_map_ops.mmap
- fix alignment of quiet build output for vmlinuz link
- BCM47xx: Use kmemdup rather than duplicating its implementation
- Netlogic: Fix 0x0x prefixes of constants.
- merge Bjorn Helgaas' series to remove most of the weak keywords
from function declarations.
- CP0 and CP1 registers are best considered treated as unsigned
values to avoid large values from becoming negative values.
- improve support for the MIPS GIC timer.
- enable common clock framework for Malta and SEAD3.
- a number of improvments and fixes to dump_tlb().
- document the MIPS TLB dump functionality in Magic SysRq.
- Cavium Octeon CN68XX improvments.
- NetLogic improvments.
- irq: Use access helper irq_data_get_affinity_mask.
- handle MSA unaligned accesses.
- a number of R6-related math-emu fixes.
- support for I6400.
- improvments to MSA support.
- add uprobes support.
- move from deprecated __initcall to arch_initcall.
- remove finish_arch_switch().

Pull ARM development updates from Russell King:
"Included in this update:
- moving PSCI code from ARM64/ARM to drivers/
- removal of some architecture internals from global kernel view
- addition of software based "privileged no access" support using the
old domains register to turn off the ability for kernel
loads/stores to access userspace. Only the proper accessors will
be usable.
- addition of early fixup support for early console
- re-addition (and reimplementation) of OMAP special interconnect
barrier
- removal of finish_arch_switch()
- only expose cpuX/online in sysfs if hotpluggable
- a number of code cleanups"

Pull locking and atomic updates from Ingo Molnar:
"Main changes in this cycle are:
- Extend atomic primitives with coherent logic op primitives
(atomic_{or,and,xor}()) and deprecate the old partial APIs
(atomic_{set,clear}_mask())
The old ops were incoherent with incompatible signatures across
architectures and with incomplete support. Now every architecture
supports the primitives consistently (by Peter Zijlstra)
- Generic support for 'relaxed atomics':
- _acquire/release/relaxed() flavours of xchg(), cmpxchg() and {add,sub}_return()
- atomic_read_acquire()
- atomic_set_release()
This came out of porting qwrlock code to arm64 (by Will Deacon)
- Clean up the fragile static_key APIs that were causing repeat bugs,
by introducing a new one:
DEFINE_STATIC_KEY_TRUE(name);
DEFINE_STATIC_KEY_FALSE(name);
which define a key of different types with an initial true/false
value.
Then allow:
static_branch_likely()
static_branch_unlikely()
to take a key of either type and emit the right instruction for the
case. To be able to know the 'type' of the static key we encode it
in the jump entry (by Peter Zijlstra)
- Static key self-tests (by Jason Baron)
- qrwlock optimizations (by Waiman Long)
- small futex enhancements (by Davidlohr Bueso)
- ... and misc other changes"

Some buffers (UVD/VM page tables) must be placed in VRAM,
but the byte restriction for moving buffers didn't took this

While looking at use cases of the wake queues in order to add support
for simple wait queues, I noticed that there was only a single user of
wake_up_interruptible_nr(), and that use was doing a single task wake
up. Have that user use the proper wake_up_interruptible() instead, and
perhaps we can even remove the function wake_up_interruptible_nr().

Hardware interrupts are enabled in the probe function, before the subdev
is registered to its v4l2_device. Until v4l2_device_register_subdev_node
is called, sd->devnode is NULL and v4l2_subdev_notify_event must not be
called.

This driver depends on VIDEO_V4L2_SUBDEV_API and needs to select HDMI.

Commit 256148246852 ("[media] tc358743: support probe from device tree")
failed to explicitly set the direction of the reset gpio. Use the
optional flag of devm_gpiod_get to make up leeway.
This is also necessary because the flag parameter will become mandatory
soon.
