Background/Reasoning:
Books:
------
* Linux Kernel Networking by Rami Rosen
While some parts are quite short and could be
more carefully explained it's still a good recomendation
for understanding linux kernel networking, (IMHO)
* Linux Treiber entwickeln:
It sure is a drawback that this is a german book.
But it's quite recent, well structured and there are also
other non-english (spanish) books/papers in this list.
Papers:
-------
* On Submitting kernel Patches
Contains 2 case studies of bigger patch sets and how (or how not)
they were merged. I found it helpful
* Tracing the Way of Data in a TCP Connection through the Linux Kernel
Since this was written by me this inclusion may be a bit biased :p
Neitherless I think this gives a good introduction on
understanding/exploring linux internals using ftrace and an overview
of Linux TCP internals.

italics. That looks nicer on epub (and html) output, as
no scroll bar will be added. Also, it will adjust line

On Sphinx/ReST notation, ``foo`` means that foo will be will be
marked as inline literal, effectively making it to be presented
as a monospaced font.
As we want this document to be parsed by Sphinx, instead of using
"foo", use ``foo`` for the names that are literal, because it is an
usual typographic convention to use monospaced fonts for functions
and language commands on documents, and we're following such
convention on the other ReST books.

As discussed at linux-doc ML, the best is to keep all documents
backward compatible with Sphinx version 1.2, as it is the latest
version found on some distros like Debian.
All books currently support it.
Please notice that, while it mentions the eventual need of
XeLaTex and texlive to build pdf files, this is not a minimal
requirement, as one could just be interested on building html
documents. Also, identifying the minimal requirements for
texlive packages is not trivial, as each distribution seems to
use different criteria on grouping LaTex functionalities.

Suggested patch solves two issues:
1) Currently documentation is unclear whether `make kselftest` should
be run before or after kernel was installed and booted. `make help`
gives a clear answer on that: "kselftest - Build and run kernel selftest
(run as root). Build, install, and boot kernel before running kselftest
on it."
2) Documentation states that `make kselftest` executes "unit" tests.
Technically it's not a _unit_ test if it requires to install an
application first. It's either integration or system test. To not to
confuse a user I suggest not to use a word "unit".

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.

The existing IOMMU bindings are able to specify the relationship between
masters and IOMMUs, but they are insufficient for describing the general
case of hotpluggable busses such as PCI where the set of masters is not
known until runtime, and the relationship between masters and IOMMUs is
a property of the integration of the system.
This patch adds a generic binding for mapping PCI devices to IOMMUs,
using a new iommu-map property (specific to PCI*) which may be used to
map devices (identified by their Requester ID) to sideband data for the
IOMMU which they master through.

Make the following changes in the HDMI gpio bindings:
- Use "-gpios" as the suffix for all the gpio names
- Move all the gpios to optional, since there are platforms that use none
of them.
- The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from
it.
- Remove the HDMI DDC clk/data gpios. They are just leftovers of an old
way to configure pinctrl properties.
- Add a missing lpm gpio used on some platforms.
Make the necessary changes in the driver to incorporate these changes.
There hasn't been any upstream DT that uses the HDMI bindings, so it's
okay to change and move around these properties.

"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

Per the PCI Firmware spec, r3.0, sec 4.5.1, on ACPI systems, the OS must
not use AER unless _OSC is present and _OSC grants AER control to the OS.
The aerdriver.forceload kernel parameter was a way to enable Linux AER
support on ACPI systems that lack _OSC or fail to grant control the the OS.
Enabling Linux AER support when the firmware doesn't want us to is a recipe
for problems, e.g., the firmware might be handling AER itself.
Remove the aerdriver.forceload kernel parameter and related supporting
code.
Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
The aerdriver.nosourceid kernel parameter was intended for working around
broken chipsets don't supply the source ID for AER events. We recently
added PCI_BUS_FLAGS_NO_AERSID, which can be set by quirks for the same
purpose.
Remove the aerdriver.nosourceid kernel parameter. For anything other than
debugging, asking users to find and use kernel parameters is a poor user
experience. Instead, we should add PCI_BUS_FLAGS_NO_AERSID quirks for any
hardware that needs it.

Merge tag 'irqchip-4.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core
Merge the first drop of irqchip updates for 4.9 from Marc Zyngier:
- ACPI IORT core code
- IORT support for the GICv3 ITS
- A few of GIC cleanups
New device support
* ad8801 dac
- new driver supporting ad8801 and ad8803 DACs.
* adc12138
- new driver supporting TI adc12130/adc12132 and adc12138 ADCs.
* ltc2485 adc
- new driver
* 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
- clear out a left over debug field from chip global data.
* hid-sensors
- avoid an unused functional warning due to rework in PM core code.
* maxim-thermocouple
- 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
st-sensors trigger is itself not using it but rather using say an hrtimer.
* ti-ads1015
- add missing of_node_put.
* vz89x
- rework to all support of new devices.
- prevent reading of a corrupted buffer.
- fixup a return value of 0/1 in a bool returning function.
Address updates
- Vlad Dogaru email address change.

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.

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
/sys/kernel/irq/18/chip_name: IR-IO-APIC
/sys/kernel/irq/18/hwirq: 18
/sys/kernel/irq/18/name: fasteoi

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
interrupt is high then the ID pin is being held high.

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.

The power button found in tps65217 device is very similar to the tps65218,
so let's enhance the driver to support both variants.
This driver enables us to use tps65217's power button as KEY_POWER on
am335x boards (directly connected button in chiliboard, accessible pin
via expansion header in beaglebone). This patch has been tested with

This patch adds code instantiating the EPLL, which is used as the

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.

PKRU is the register that lets you disallow writes or all access to a given
protection key.
The XSAVE hardware defines an "init state" of 0 for PKRU: its most
permissive state, allowing access/writes to everything. Since we start off
all new processes with the init state, we start all processes off with the
most permissive possible PKRU.
This is unfortunate. If a thread is clone()'d [1] before a program has
time to set PKRU to a restrictive value, that thread will be able to write
to all data, no matter what pkey is set on it. This weakens any integrity
guarantees that we want pkeys to provide.
To fix this, we define a very restrictive PKRU to override the
XSAVE-provided value when we create a new FPU context. We choose a value
that only allows access to pkey 0, which is as restrictive as we can
practically make it.
This does not cause any practical problems with applications using
protection keys because we require them to specify initial permissions for
each key when it is allocated, which override the restrictive default.
In the end, this ensures that threads which do not know how to manage their
own pkey rights can not do damage to data which is pkey-protected.
I would have thought this was a pretty contrived scenario, except that I
heard a bug report from an MPX user who was creating threads in some very
early code before main(). It may be crazy, but folks evidently _do_ it.

This is a slightly larger batch of fixes that we've been sitting on a few

slightly larger and worth pointing out:
- A set of patches to OMAP to deal with hwmod for RTC on am33xx (beaglebone
SoC, among others). It's the only clock that ever has a valid offset of 0,
so a new flag needed introduction once this problem was discovered.
- A collection of CCI fixes for performance counters discovered once people

This signal exist on all the SMSC911x devices, it is just not

Both these lines are routed to the SoC on the Qualcomm APQ8060

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].
Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

- 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

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.

Add "blue-and-red-wiring"-device tree property and update devicetree
binding document.
The red and blue components are reversed between 24 and 16 bit modes
on am335x LCDC output pins. To get 24 RGB format the red and blue
wires has to be crossed and this in turn causes 16 colors output to be
in BGR format. With straight wiring the 16 color is RGB and 24 bit is
BGR.
The new property describes whether the red and blue wires are crossed
or not. If the property is not present or its value is not recognized
the legacy mode is assumed. The legacy configuration supports RGB565,
RGB888 and XRGB8888 formats. However, depending on wiring, the red and
blue colors are swapped in either 16 or 24-bit color modes.
For more details see section 3.1.1 in AM335x Silicon Errata:

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
