Some applications that run on HPC clusters are designed around the
availability of RAM and the overcommit ratio is fine tuned to get the
maximum usage of memory without swapping. With growing memory, the
1%-of-all-RAM grain provided by overcommit_ratio has become too coarse
for these workload (on a 2TB machine it represents no less than 20GB).
This patch adds the new overcommit_kbytes sysctl variable that allow a
much finer grain.

Many load balancing and workload placing programs check /proc/meminfo to
estimate how much free memory is available. They generally do this by
adding up "free" and "cached", which was fine ten years ago, but is
pretty much guaranteed to be wrong today.
It is wrong because Cached includes memory that is not freeable as page
cache, for example shared memory segments, tmpfs, and ramfs, and it does
not include reclaimable slab memory, which can take up a large fraction
of system memory on mostly idle systems with lots of files.
Currently, the amount of memory that is available for a new workload,
without pushing the system into swap, can be estimated from MemFree,
Active(file), Inactive(file), and SReclaimable, as well as the "low"
watermarks from /proc/zoneinfo.
However, this may change in the future, and user space really should not
be expected to know kernel internals to come up with an estimate for the
amount of free memory.
It is more convenient to provide such an estimate in /proc/meminfo. If
things change in the future, we only have to change it in one place.

Pull GPIO tree bulk changes from Linus Walleij:
"A big set this merge window, as we have much going on in this
subsystem. The changes to other subsystems (notably a slew of ARM
machines as I am doing away with their custom APIs) have all been
ACKed to the extent possible.
Major changes this time:
- Some core improvements and cleanups to the new GPIO descriptor API.
This seems to be working now so we can start the exodus to this
API, moving gradually away from the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move the few
GPIO ACPI clients we have to the GPIO descriptor API right *now*
before we go any further. We actually managed to contain this
*before* we started to litter the kernel with yet another hackish
global numberspace for the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have been
migrated to use the GPIO descriptors rather than fixed number
assignments. Tegra machine has been migrated as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those
should be really good examples of how I expect a nice GPIO driver
to look these days.
- Do away with custom GPIO implementations on a major part of the ARM
machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the
same in the horribly convoluted Samsung S3C include forest. We
expect to continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line is used
for IRQs and can then enforce some semantics such as disallowing a
GPIO line marked as in use for IRQ to be switched to output mode.
- Drop all use of irq_set_chip_and_handler_name(). The name provided
in these cases were just unhelpful tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em 74x164 and
msm drivers.
- Some non-urgent bug fixes here and there, duplicate #includes and
that usual kind of cleanups"

The EC has specific timing it requires. Add support for an optional delay
after raising CS to fix timing issues. This is configurable based on
a DT property "google,cros-ec-spi-msg-delay".
If this property isn't set, then no delay will be added. However, if set
it will cause a delay equal to the value passed to it to be inserted at
the end of a transaction.

Pull driver core / sysfs patches from Greg KH:
"Here's the big driver core and sysfs patch set for 3.14-rc1.
There's a lot of work here moving sysfs logic out into a "kernfs" to
allow other subsystems to also have a virtual filesystem with the same
attributes of sysfs (handle device disconnect, dynamic creation /
removal as needed / unneeded, etc)
This is primarily being done for the cgroups filesystem, but the goal
is to also move debugfs to it when it is ready, solving all of the
known issues in that filesystem as well. The code isn't completed
yet, but all should be stable now (there is a big section that was
reverted due to problems found when testing)

This adds interrupt functionality for i2c chips to the driver.
They can act as a interrupt-controller and generate interrupts, if
the inputs change.
This is tested with a mcp23017 chip on an arm based platform.
v3:
- be a bit more clear that the irq functionality is also available
on spi versions of the chips, but the linux driver does not support
this yet
v2:
- some more word about irq-mirror property in binding doc
- use of_read_bool instead of of_find_property for
"interrupt-contrller" and "irq-mirror"
- cache the "interrupt-controller" for remove function
- do set the irq-mirror bit only if device is marked as
interrupt-controller
- do create the irq mapping and setup of irq_desc of all possible
interrupts in probe path instead of in gpio_to_irq
- mark gpios as in use as interrupts in irq in irq_startup and
unlock it in irq_shutdown
- rename virq to child_irq
- remove dev argument from mcp23s08_irq_setup function
- move gpiochip_add before mcp23s08_irq_setup in probe path

Add disable_cpu_apicid kernel parameter. To use this kernel parameter,
specify an initial APIC ID of the corresponding CPU you want to
disable.
This is mostly used for the kdump 2nd kernel to disable BSP to wake up
multiple CPUs without causing system reset or hang due to sending INIT
from AP to BSP.
Kdump users first figure out initial APIC ID of the BSP, CPU0 in the
1st kernel, for example from /proc/cpuinfo and then set up this kernel
parameter for the 2nd kernel using the obtained APIC ID.
However, doing this procedure at each boot time manually is awkward,
which should be automatically done by user-land service scripts, for
example, kexec-tools on fedora/RHEL distributions.
This design is more flexible than disabling BSP in kernel boot time
automatically in that in kernel boot time we have no choice but
referring to ACPI/MP table to obtain initial APIC ID for BSP, meaning
that the method is not applicable to the systems without such BIOS
tables.
One assumption behind this design is that users get initial APIC ID of
the BSP in still healthy state and so BSP is uniquely kept in
CPU0. Thus, through the kernel parameter, only one initial APIC ID can
be specified.
In a comparison with disabled_cpu_apicid, we use read_apic_id(), not
boot_cpu_physical_apicid, because on some platforms, the variable is
modified to the apicid reported as BSP through MP table and this
function is executed with the temporarily modified
boot_cpu_physical_apicid. As a result, disabled_cpu_apicid kernel
parameter doesn't work well for apicids of APs.
Fixing the wrong handling of boot_cpu_physical_apicid requires some
reviews and tests beyond some platforms and it could take some
time. The fix here is a kind of workaround to focus on the main topic
of this patch.

The LOCK and UNLOCK barriers as described in our barrier document are
generally known as ACQUIRE and RELEASE barriers in other literature.
Since we plan to introduce the acquire and release nomenclature in
generic kernel primitives we should amend the document to avoid
confusion as to what an acquire/release means.

This patch implements a device-tree-only CPU DAI driver for Freescale ESAI
controller that supports:
- 12 channels playback and 8 channels record.
[ Some of the inner transmitters and receivers are sharing same group of
pins. So the maxmium 12 output or 8 input channels are only valid if
there is no pin conflict occurring to it. ]
- Independent (asynchronous mode) or shared (synchronous mode) transmit and
receive sections with separate or shared internal/external clocks and frame
syncs, operating in Master or Slave mode.
[ Current ALSA seems not to allow CPU DAI drivers to configure DAI format
separately for PLAYBACK and CAPTURE. So this first version only supports
the case that uses the same DAI format for both directions. ]
- Various DAI formats: I2S, Left-Justified, Right-Justified, DSP-A and DSP-B.
- Programmable word length (8, 16, 20 or 24bits)
- Flexible selection between system clock or external oscillator as input
clock source, programmable internal clock divider and frame sync generation.

Documentation/i2c/fault-codes illustrates EINVAL error code
as follows:
"One example would be a driver trying an SMBus Block Write
with block size outside the range of 1-32 bytes."
However, the actual implementation of i2c subsystem truncates
data length to be 32 bytes.
Hence this example cannot happen anymore, and since it's obsolete,
let's simply remove it from Documentation/i2c/fault-codes.

Update extcon for v3.14
This patchset add new driver of extcon-max14577.c which detect various external
connector and fix minor issue of extcon provider driver(extcon-arizona/palams/
gpio.c). Also, update documentation of previous 'switch' porting guide and
extcon git repository url.
Detailed description for patchset:
- New driver of extcon-max14577.c
: Add extcon-max14577.c drvier to support Maxim MUIC(Micro USB Interface
Controller) which detect USB/TA/JIG/AUDIO-DOCK and additional accessory
according to each resistance when connected external connector.
- extcon-arizoan.c driver
: Code clean to use define macro instead of hex value
: Fix minor issue to reset back to our staring state
: Fix race with microphone detection and removal
- extcon-palmas.c driver
: Fix minor issue and renaming compatible string of Devicetree
- extcon-gpio.c driver
: Fix bug about ordering initialization of gpio pin on probe()
: Send uevent after wakeup from suspend state because some SoC
haven't wakeup interrupt on suspend state.
- Documentation (Documentation/extcon/porting-android-switch-class)
: Fix switch class porting guide
- Update extcon git repository url
