This document is on good shape for ReST: all it was needed was
to fix the section markups, add a toctree, convert the tables
and add a few code/quote blocks.
While not strictly required, I opted to use lowercase for
the titles, just like the other books that were converted
to Sphinx.

In a typical IPvlan L3 setup where master is in default-ns and
each slave is into different (slave) ns. In this setup egress
packet processing for traffic originating from slave-ns will
hit all NF_HOOKs in slave-ns as well as default-ns. However same
is not true for ingress processing. All these NF_HOOKs are
hit only in the slave-ns skipping them in the default-ns.
IPvlan in L3 mode is restrictive and if admins want to deploy
iptables rules in default-ns, this asymmetric data path makes it
impossible to do so.
This patch makes use of the l3_rcv() (added as part of l3mdev
enhancements) to perform input route lookup on RX packets without
changing the skb->dev and then uses nf_hook at NF_INET_LOCAL_IN
to change the skb->dev just before handing over skb to L4.

This short series convers device-drivers.tmpl into the RST format, splits
it up, and sets up the result under Documentation/driver-api/. For added
fun, I've taken one top-level file (hsi.txt) and folded it into the
document as a way of showing the direction I'm thinking I would like things
to go. There is plenty more of this sort of work that could be done, to
say the least - this is just a beginning!
The formatted results can be seen at:
http://static.lwn.net/kerneldoc/driver-api/index.html
As part of the long-term task to turn Documentation/ into less of a horror
movie, I'd like to collect documentation of the driver-specific API here.
Arguably gpu/ and the media API stuff should eventually move here, though
we can discuss the color of that particular shed some other day.
Meanwhile, I'd appreciate comments on the general idea.

- Expedited grace-period changes, most notably avoiding having
user threads drive expedited grace periods, using a workqueue
instead.
- Miscellaneous fixes, including a performance fix for lists
that was sent with the lists modifications (second URL below).
- CPU hotplug updates, most notably providing exact CPU-online
tracking for RCU. This will in turn allow removal of the
checks supporting RCU's prior heuristic that was based on the
assumption that CPUs would take no longer than one jiffy to

This makes it possible to create a set of LEDs for Mellanox systems:
"msx6710", "msx6720", "msb7700", "msn2700", "msx1410", "msn2410",
"msb7800", "msn2740", "msn2100".
Driver obtains LED devices according to system configuration, provided
through system DMI data, like mlxcpld:fan1:green, mlxcpld:fan1:red and
creates devices in form: "devicename:colour:function".
LED setting is controlled through on board CPLD Lattice device.
For setting particular LED off, solid, blink:
echo 0 > /sys/class/leds/mlxcpld\:status\:green/brightness
echo 1 > /sys/class/leds/mlxcpld\:status\:green/brightness
echo timer > /sys/class/leds/mlxcpld\:status\:green/trigger
On module probing all LEDs are set green, on removing - off.
Last setting overwrites previous, f.e. sequence for
changing LED from green - red - green:
echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness
echo 1 > /sys/class/leds/mlxcpld\:psu\:red/brightness
echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness
Note: LEDs cannot be turned on/off simultaneously.

* mxc6255
- add support for the mxc6225 part name and fixup the ID check so it works.
* vz89x VOC sensor
- add support for the vz89te part which drops the voc_short channel and adds
CRCs compared to other supported parts.
New features
* core
- immutable triggers. These effectively grant exclusive control over a
trigger. The typical usecase is a device representing an analog part
(perhaps a MUX) that needs to control the sampling of a downstream
ADC.
- resource managed trigger registration and triggered_buffer_init.
- iio_push_event now protected against case of the event interface
registration not having yet occured. Only matters if an interrupt
can occur during this window - might happen on shared interrupt lines.
- helper to let a driver query if the trigger it is using is provided by
itself (using the convention of both device and trigger having the same
parent).
* tools
- iio-utils. Used channel modifier scaling in preference to generic scaling
when both exist.
* at91-adc
- Add support for touchscreen switches closure time needed by some newer
parts.
* stx104
- support the ADC channels on this ADC/DAC board. As these are the primary
feature of the board also move the driver to the iio/adc directory.
* sx9500
- device tree bindings.
Cleanups / Fixes
* ad5755
- fix an off-by-one on devnr limit check (introduced earlier this cycle)
* ad7266
- drop NULL check on devm_regulator_get_optional as it can't return NULL.
* ak8974
- avoid an unused functional warning due to rework in PM core code.
- remove .owner field setting as done by i2c_core.
* ina2xx

* hid-sensors

- fix non static symbol warnings.
* ms5611
- fetch and enable regulators unconditionally when they aren't optional.
* sca3000
- whitespace cleanup.
* st_sensors
- fetch and enable regulators unconditionally rather than having them
supported as optional regulators (missunderstanding on my part amongst
others a while back)
- followup to previous patch fixes error checking on the regulators.
- mark symbols static where possible.
- use the 'is it my trigger' help function. This prevents the odd case
of another device triggering from the st-sensors trigger whilst the

* ti-ads1015
- add missing of_node_put.
* vz89x

This time around we have 92 non-merge commits. Most
of the changes are in drivers/usb/gadget (40.3%)
with drivers/usb/gadget/function being the most
active directory (27.2%).
As for UDC drivers, only dwc3 (26.5%) and dwc2
(12.7%) have really been active.
The most important changes for dwc3 are better
support for scatterlist and, again, throughput
improvements. While on dwc2 got some minor stability
fixes related to soft reset and FIFO usage.
Felipe Tonello has done some good work fixing up our
f_midi gadget and Tal Shorer has implemented a nice
API change for our ULPI bus.
Apart from these, we have our usual set of
non-critical fixes, spelling fixes, build warning
fixes, etc.

usb: patches for v4.9 merge window
This time around we have 92 non-merge commits. Most
of the changes are in drivers/usb/gadget (40.3%)
with drivers/usb/gadget/function being the most
active directory (27.2%).
As for UDC drivers, only dwc3 (26.5%) and dwc2
(12.7%) have really been active.
The most important changes for dwc3 are better
support for scatterlist and, again, throughput
improvements. While on dwc2 got some minor stability
fixes related to soft reset and FIFO usage.
Felipe Tonello has done some good work fixing up our
f_midi gadget and Tal Shorer has implemented a nice
API change for our ULPI bus.
Apart from these, we have our usual set of
non-critical fixes, spelling fixes, build warning
fixes, etc.
Four more SoCs converted to the new clock framework (A31, A31s, A23 and
A33).

Information about interrupts is exposed via /proc/interrupts, but the
format of that file has changed over kernel versions and differs across
architectures. It also has varying column numbers depending on hardware.
That all makes it hard for tools to parse.
To solve this, expose the information through sysfs so each irq attribute
is in a separate file in a consistent, machine parsable way.
This feature is only available when both CONFIG_SPARSE_IRQ and
CONFIG_SYSFS are enabled.
Examples:
/sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7

1. Support the extcon property and add the synchronization APIs.
- This feature supports the extcon property for external connector
because each external connector might have the property according to
the H/W design.
- The property name should keep the following style.
: EXTCON_PROP_USB_[property_name]
: EXTCON_PROP_CHG_[property_name]
: EXTCON_PROP_JACK_[property_name]
: EXTCON_PROP_DISP_[property_name]
- Add the new extcon APIs to support the extcon property.
: extcon_set_property()
: extcon_get_property()
: extcon_set_property_capability()
: extcon_get_property_capability()
- Add the new synchronization extcon APIs.
: This feature adds the synchronization extcon APIs to support the noti
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.
The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().
: extcon_sync()
: extcon_set_state_sync()
: extcon_set_property_sync()
- Change the name of existing APIs.
: extcon_set_cable_state_() -> extcon_set_cable()
: extcon_get_cable_state_() -> extcon_get_cable()
2. Add the extcon type to group the connector into five category.
- EXTCON_TYPE_USB : USB connector
- EXTCON_TYPE_CHG : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector
3. Add the new property for external connector.
- EXTCON_PROP_USB_VBUS
- EXTCON_PROP_USB_TYPEC_POLARITY
- EXTCON_PROP_USB_SS (SuperSpeed)
- EXTCON_PROP_DISP_HPD (Hot Plug Detect)
4. Add the new type of external connector.
- EXTCON_DISP_DP : Display Port
- EXTCON_DISP_HMD : Head Mounted Device
- EXTCON_CHG_WPT : Wireless Power Transfer device
5. Add the new extcon driver.
- Qualcomm SPMI PMIC USB id detection driver detects whether
EXTCON_USB_HOST is attached or detached. (extcon-qcom-spmi-mis.c)
6. Remove the usage of extcon_update_state() and old extcon_set_state()
- Both extcon_update_state() and extcon_set_state() should change the state
of all external connectors with bit masking handling. It may occur the
problem. Instead, extcon provides the extcon_set/get_state() functions.
7. Fix the minor issues on extcon drivers.

Some Qualcomm PMICs have a misc device that performs USB id pin
detection via an interrupt. When the interrupt triggers, we
should read the interrupt line to see if it has gone high or low.
If the interrupt is low then the ID pin is grounded, and if the

The driver has supported touchscreen-fw-name to specify the firmware to
load since it has been merged, but this was omitted from the dt-binding
documentation.
During review of adding touchscreen-fw-name to the binding documentation
it was brought up that there is a standard property name called
"firmware-name" for this, which should be used.
Since there are no users of touchscreen-fw-name yet, this commit
adds documentation of "firmware-name" to the dt-binding documentation
and switches the driver over to use this.
This commit also makes the driver add a "silead/" prefix to the
firmware name from dt before calling request_firmware. That the
firmware files are stored under /lib/firmware/silead under Linux
is an implementation detail and does not belong in devicetree.

This driver provides PHY init support in a generic way and can be bound
with XHCI controller driver.
There aren't any public datasheets from Broadcom so we can't have nice
defines for all used bits. It means we just follow Broadcom's
initialization procedure using their magic values. We were quite lucky
actually that Broadcom put some comments in their SDK reference code

Pull power management fixes from Rafael Wysocki:
"This includes a PM QoS framework fix from Tejun to prevent interrupts
from being enabled unexpectedly during early boot and a cpufreq
documentation fix.
Specifics:
- If the PM QoS framework invokes cancel_delayed_work_sync() during
early boot, it will enable interrupts which is not expected at that
point, so prevent it from happening (Tejun Heo)
- Fix cpufreq statistic documentation to follow a recent change in
behavior that forgot to update it as appropriate (Jean Delvare)"

cpufreq-stats: Minor documentation fix
PM / QoS: avoid calling cancel_delayed_work_sync() during early boot
This patch adds code instantiating the EPLL, which is used as the
audio subsystem's root clock.
The requirement to specify the external root clock in clocks property
is documented. Having the consumer 'clocks' property ensures proper
initialization order by explicitly specifying dependencies in DT.
It prevents situations when the SoC's clock controller driver has
initialized, the external oscillator clock is not yet registered
and setting clock frequencies through assigned-clock-rates property
doesn't work properly due to unknown external oscillator frequency.

Exynos5410 Audio Subsystem Clock Controller, comparing to the already

so a new compatible string is added.
It is not clear from the Exynos5410 User's Manual released on 2012.03.09

- A set of patches to OMAP to deal with hwmod for RTC on am33xx (beaglebone

so a new flag needed introduction once this problem was discovered.
- A collection of CCI fixes for performance counters discovered once people

- An optional PME (power management event) interrupt line that
can be utilized to wake up the system on network activity.
This signal exist on all the SMSC911x devices, it is just not
very often routed.
Both these lines are routed to the SoC on the Qualcomm APQ8060
Dragonboard and thus needs to be bound in the device tree.

- The guide currently says to pad the structure to a multiple of
64-bits. This is not necessary in cases where the structure contains
no 64-bit types. Clarify this concept to avoid unnecessary padding.
- When using __u64 to hold user pointers, blindly trying to do a cast to
a void __user * may generate a warning on 32-bit systems about a cast
from an integer to a pointer of different size. There is a macro to
deal with this which hides an ugly double cast. Add a reference to
this macro.

Don't expose skbs to in-kernel users, such as the AFS filesystem, but
instead provide a notification hook the indicates that a call needs
attention and another that indicates that there's a new call to be
collected.
This makes the following possibilities more achievable:
(1) Call refcounting can be made simpler if skbs don't hold refs to calls.
(2) skbs referring to non-data events will be able to be freed much sooner
rather than being queued for AFS to pick up as rxrpc_kernel_recv_data
will be able to consult the call state.
(3) We can shortcut the receive phase when a call is remotely aborted
because we don't have to go through all the packets to get to the one
cancelling the operation.
(4) It makes it easier to do encryption/decryption directly between AFS's
buffers and sk_buffs.
(5) Encryption/decryption can more easily be done in the AFS's thread
contexts - usually that of the userspace process that issued a syscall
- rather than in one of rxrpc's background threads on a workqueue.
(6) AFS will be able to wait synchronously on a call inside AF_RXRPC.
To make this work, the following interface function has been added:
int rxrpc_kernel_recv_data(
struct socket *sock, struct rxrpc_call *call,
void *buffer, size_t bufsize, size_t *_offset,
bool want_more, u32 *_abort_code);
This is the recvmsg equivalent. It allows the caller to find out about the
state of a specific call and to transfer received data into a buffer
piecemeal.
afs_extract_data() and rxrpc_kernel_recv_data() now do all the extraction
logic between them. They don't wait synchronously yet because the socket
lock needs to be dealt with.
Five interface functions have been removed:
rxrpc_kernel_is_data_last()
rxrpc_kernel_get_abort_code()
rxrpc_kernel_get_error_number()
rxrpc_kernel_free_skb()
rxrpc_kernel_data_consumed()
As a temporary hack, sk_buffs going to an in-kernel call are queued on the
rxrpc_call struct (->knlrecv_queue) rather than being handed over to the
in-kernel user. To process the queue internally, a temporary function,
temp_deliver_data() has been added. This will be replaced with common code
between the rxrpc_recvmsg() path and the kernel_rxrpc_recv_data() path in a
future patch.

Make the location monitor callback function prototype more useful by
changing the argument from an integer to a void pointer.
All VME bridge drivers were simply passing the location monitor index
(e.g. 0-3) as the argument to these callbacks. It is much more useful
to pass back a pointer to data that the callback-registering driver
cares about.
There appear to be no in-kernel callers of vme_lm_attach (or
vme_lme_request for that matter), so this change only affects the VME
subsystem and bridge drivers.
This has been tested with Tsi148 hardware, but the CA91Cx42 changes

The ESP8089 chips can mostly be enumerated via their sdio interface,
but they are clocked by an external crystal which may differ from one
board to the other.
This commit adds a binding for the sdio child node for these chips,
allowing to specify the external crystal type (for now, this binding
could be be extended with e.g. OOB irq support later).
The Android driver for this chip uses a text file with key,value pairs
which gets loaded as firmware to pass this info to the firmware.
The "esp,crystal_26M_en" name is chosen to match the crystal_26M_en
key-name in that text file.
Note that at this point there only is an out of tree driver for this
hardware, there is no clear timeline / path for merging this. Still
I believe it would be good to specify the binding for this in tree
now, so that any future migration to an in tree driver will not cause
compatiblity issues.

Userspace can begin and suspend a transaction within the signal
handler which means they might enter sys_rt_sigreturn() with the
processor in suspended state.
sys_rt_sigreturn() wants to restore process context (which may have
been in a transaction before signal delivery). To do this it must
restore TM SPRS. To achieve this, any transaction initiated within the
signal frame must be discarded in order to be able to restore TM SPRs
as TM SPRs can only be manipulated non-transactionally..

It isn't clear exactly if there is really a use case for userspace
returning with a suspended transaction, however, doing so doesn't (on
its own) constitute a bad frame. As such, this patch simply discards
the transactional state of the context calling the sigreturn and
continues.

switchdev_port_fwd_mark_set() is used to set the 'offload_fwd_mark' of
port netdevs so that packets being flooded by the device won't be
flooded twice.
It works by assigning a unique identifier (the ifindex of the first
bridge port) to bridge ports sharing the same parent ID. This prevents
packets from being flooded twice by the same switch, but will flood
packets through bridge ports belonging to a different switch.
This method is problematic when stacked devices are taken into account,
such as VLANs. In such cases, a physical port netdev can have upper
devices being members in two different bridges, thus requiring two
different 'offload_fwd_mark's to be configured on the port netdev, which
is impossible.
The main problem is that packet and netdev marking is performed at the
physical netdev level, whereas flooding occurs between bridge ports,
which are not necessarily port netdevs.
Instead, packet and netdev marking should really be done in the bridge
driver with the switch driver only telling it which packets it already
forwarded. The bridge driver will mark such packets using the mark
assigned to the ingress bridge port and will prevent the packet from
being forwarded through any bridge port sharing the same mark (i.e.
having the same parent ID).
Remove the current switchdev 'offload_fwd_mark' implementation and
instead implement the proposed method. In addition, make rocker - the
sole user of the mark - use the proposed method.

From the old description people still can't get what's the exact
difference between nr_cpus and maxcpus. Especially in kdump kernel
nr_cpus is always suggested if it's implemented in the ARCH. The
reason is nr_cpus is used to limit the max number of possible cpu
in system, the sum of already plugged cpus and hot plug cpus can't
exceed its value. However maxcpus is used to limit how many cpus
are allowed to be brought up during bootup.

The TX settings can be calibrated for particular hardware. The
phy is reset by Linux, so this cannot be handled by the bootloader.
The TRM mentions that the maximum resistance should be used for the
DN/DP calibration in order to pass USB certification.
The values for the TX registers are poorly described in the TRM.
The meanings of the register values were taken from another

Now that the dsa_switch_driver structure contains only function pointers
as it is supposed to, rename it to the more appropriate dsa_switch_ops,
uniformly to any other operations structure in the kernel.
No functional changes here, basically just the result of something like:
s/dsa_switch_driver *drv/dsa_switch_ops *ops/g
However keep the {un,}register_switch_driver functions and their
dsa_switch_drivers list as is, since they represent the -- likely to be
deprecated soon -- legacy DSA registration framework.
In the meantime, also fix the following checks from checkpatch.pl to

rsrc-card has board specific compatible (= lager/koelsh), but these were
created as 1st prototype, and it is used in my test environment only.
Now normal user can use generic compatible (= renesas,rsrc-card).
Removing these board specific compatible doesn't breake compatibility.
This patch remove these.

Storing this value will help prevent unwinders from getting out of sync
with the function graph tracer ret_stack. Now instead of needing a
stateful iterator, they can compare the return address pointer to find
the right ret_stack entry.
Note that an array of 50 ftrace_ret_stack structs is allocated for every
task. So when an arch implements this, it will add either 200 or 400
bytes of memory usage per task (depending on whether it's a 32-bit or
64-bit platform).

Device support
* ak8974
- New driver and bindings for this 2009 vintage magnetometer (it was very
popular back then!)
* atlas-ph-sensor
- ORP sensor support(I had to look up what one of these was)
* cio-dac
- New driver for Measurement Computing DAC boards
* dmard06
- New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
- New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
- max6675 and max31855 new driver
* mt6577 auxdac
- new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
hardware.

- new driver for this TI single channel differential ADC.
* vcnl4000
- support vcnl4010 and vcnl4020 which are compatible for all features
currently supported by this driver.
New features
* Core
- Allow retrieving of underlying iio_dev from a callback buffer handle.
This is needed to allow client drivers to perform operations such as
configuring the trigger used.
* hid-sensors
- asynchronous resume support to avoid really long resume times.
* kxcjk-1013
- add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
- lsiio now enumerates processed as well as raw channels.
Cleanup
* ad7298
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ad7793
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ade7854
- checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
- Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* hdc100x
- Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
- Add driver specific prefixes to defines and function names.
- Remove excessive logging.
- Drop newlines which add nothing to readability.
- General tidying up of comments.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
- Add driver specific prefixes to defines, enums and function names.
- Drop comma's from available attribute output as not ABI compliant.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
- devicetree bindings.
* mag3110
- This one wasn't locking to protect against mode switches during
raw_reads. Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
- Fix missing selects for triggered buffer support in Kconfig.
* nau7802
- Use complete instead of complete_all as only one completion at a time.
* sx9500
- Use complete instead of complete_all as only one completion at a time.
* us5182d
- Add a missing error code asignment instead of checking the result of
an already checked statement.
* vcnl4000
- Use BIT macro where appropriate.
- Refactor return codes in read_raw callback.
- Add some missing locking for concurrent accesses to the device.

Change kprobe/uprobe-tracer to show the arguments type-casted
with u8/u16/u32/u64 in decimal digits instead of hexadecimal.
To minimize compatibility issue, the arguments without type
casting are typed by x64 (or x32 for 32bit arch) by default.
Note: all arguments set by old perf probe without types are
shown in decimal by default.
