The "hisilicon,pcie-almost-ecam" binding goes against the usual DT
conventions, and is non-sensical in that it describes the IP based on
what it isn't. Fix the DT binding with "hisilicon,hip06-pcie-ecam"
and "hisilicon,hip07-pcie-ecam".

This file is actually quite complex, and required several
manual handwork:
- add a title for the document;
- use the right tags for monospaced fonts;
- use c references where needed;
- adjust cross-reference to writing_usb_driver.rst
- hightlight cross-referenced lines.
With regards to C code snippet line highlights, the better would be
to use :linenos: for the C code snippets that are referenced by
the line number. However, at least with Sphinx 1.4.9, enabling
it cause the line number to be misaligned with the code,
making it even more confusing. So, instead, let's use
:emphasize-lines: tag to mark the lines that are referenced

Add bi-directional and output-enable pin configuration properties.
bi-directional allows to specify when a pin shall operate in input and
output mode at the same time. This is particularly useful in platforms
where input and output buffers have to be manually enabled.
output-enable is just syntactic sugar to specify that a pin shall
operate in output mode, ignoring the provided argument.
This pairs with input-enable pin configuration option.

This patch adds support for usb role swap via sysfs "role".
For example:
1) Connect a usb cable using 2 Salvator-X boards.
- For A-Device, the cable is connected to CN11 (USB3.0 ch0).
- For B-Device, the cable is connected to CN9 (USB2.0 ch0).
2) On A-Device, you input the following command:
# echo peripheral > /sys/devices/platform/soc/ee020000.usb/role
3) On B-Device, you input the following command:
# echo host > /sys/devices/platform/soc/ee080200.usb-phy/role
Then, the A-Device acts as a peripheral and the B-Device acts as
a host. Please note that A-Device must input the following command
if you want the board to act as a host again.
# echo host > /sys/devices/platform/soc/ee020000.usb/role

Introduce the "lrclk-strength" property to allow LRCLK pad drive strength
to be changed via device tree.
When running a stress playback loop test on a mx6dl wandboard channel
swap can be noticed on about 10% of the times.
While debugging this issue I noticed that when probing the SGTL5000

the probe the swap started to happen again.
After changing the LRCLK pad drive strength to the maximum value the
issue is gone.

Range based cpu lists are commonly used along with bitmask based cpu files
in various subsystems throughout the kernel.

Detailed description for this pull request:
1. Add new 'extcon-intel-cht-wc.c' driver
- Intel Cherrytrail Whiskey Cove PMIC extcon driver supports
the detection of the charger connectors and the control.
2. Add new extcon API to monitor the all external connectors.
- The extcon consumer might need to monitor the all supported external
connectors from the extcon device. Before, the extcon consumer
should have each notifier_block structure for each external connector.
In order to support the requirement, the extcon adds new
extcon_register_notifier_all() API. The extcon consumer is able
to monitor the state change of all supported external connectors
from the extcon device by using only one notifier_block.
- extcon_(register|unregister)_notifier_all(struct extcon_dev *edev
struct notifier_block *nb)
- devm_extcon_(register|unregister)_notifier_all(struct device *dev,
struct extcon_dev *edev
struct notifier_block *nb)
3. Remove porting compatibility of old switch class
- The extcon removes the porting compatibility of old switch class
because there are no any use-case and requirement of switch class.
4. Update the extcon drivers and Fix the minor issues
- Revert the ACPI gpio interface on the extcon-usb-gpioc.c.
- Fix the issues related to the suspend-to-ram for both extcon-usb-gpio.c
and extcon-palmas.c.
- Add warning message for extcon-arizona.c when headphone detection is not
finished.

Merge tag 'extcon-next-for-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next
Update extcon for 4.12
Detailed description for this pull request:
1. Add new 'extcon-intel-cht-wc.c' driver
- Intel Cherrytrail Whiskey Cove PMIC extcon driver supports
the detection of the charger connectors and the control.
2. Add new extcon API to monitor the all external connectors.
- The extcon consumer might need to monitor the all supported external
connectors from the extcon device. Before, the extcon consumer
should have each notifier_block structure for each external connector.
In order to support the requirement, the extcon adds new
extcon_register_notifier_all() API. The extcon consumer is able
to monitor the state change of all supported external connectors
from the extcon device by using only one notifier_block.
- extcon_(register|unregister)_notifier_all(struct extcon_dev *edev
struct notifier_block *nb)
- devm_extcon_(register|unregister)_notifier_all(struct device *dev,
struct extcon_dev *edev
struct notifier_block *nb)
3. Remove porting compatibility of old switch class
- The extcon removes the porting compatibility of old switch class
because there are no any use-case and requirement of switch class.
4. Update the extcon drivers and Fix the minor issues
- Revert the ACPI gpio interface on the extcon-usb-gpioc.c.
- Fix the issues related to the suspend-to-ram for both extcon-usb-gpio.c
and extcon-palmas.c.
- Add warning message for extcon-arizona.c when headphone detection is not
finished.

variable-sized descriptors providing information about various compile-

structure containing most run-time resident memory regions set up by
coreboot).
These definitions allow kernel drivers to easily access data contained

When we merged the Gemini interrupt controller it was not yet
discovered that this IP block is actually a standard Faraday
Technology interrupt controller.
As the IP block will probably appear in other designs as well,
let's augment the DT bindings to reflect that it is first and
foremost a standard Faraday part with a function name (FTINTC010)
so that people reusing the IP easily find the driver they need.
Sorry for the mistakes due to lack of information.

Recent pinctrl changes to allow dynamic allocation of pins exposed one
more issue with the pinctrl pins claimed early by the controller itself.
This caused a regression for IMX6 pinctrl hogs.
Before enabling the pin controller driver we need to wait until it has
been properly initialized, then claim the hogs, and only then enable it.
To fix the regression, split the code into pinctrl_claim_hogs() and
pinctrl_enable(). And then let's require that pinctrl_enable() is always
called by the pin controller driver when ready after calling
pinctrl_register_and_init().

work for hogs")

SP800-56A defines the use of DH with key derivation function based on a
counter. The input to the KDF is defined as (DH shared secret || other
information). The value for the "other information" is to be provided by
the caller.
The KDF is implemented using the hash support from the kernel crypto API.
The implementation uses the symmetric hash support as the input to the
hash operation is usually very small. The caller is allowed to specify
the hash name that he wants to use to derive the key material allowing
the use of all supported hashes provided with the kernel crypto API.
As the KDF implements the proper truncation of the DH shared secret to
the requested size, this patch fills the caller buffer up to its size.
The patch is tested with a new test added to the keyutils user space
code which uses a CAVS test vector testing the compliance with
SP800-56A.

Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
Keyrings recently gained restrict_link capabilities that allow
individual keys to be validated prior to linking. This functionality
was only available using internal kernel APIs.
With the KEYCTL_RESTRICT_KEYRING command existing keyrings can be
configured to check the content of keys before they are linked, and
then allow or disallow linkage of that key to the keyring.
To restrict a keyring, call:
keyctl(KEYCTL_RESTRICT_KEYRING, key_serial_t keyring, const char *type,
const char *restriction)
where 'type' is the name of a registered key type and 'restriction' is a
string describing how key linkage is to be restricted. The restriction
option syntax is specific to each key type.
Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
The restrict_link functions used to validate keys as they are linked
to a keyring can be associated with specific key types. Each key type
may be loaded (or not) at runtime, so lookup of restrict_link
functions needs to be part of the key type implementation to ensure
that the requested keys can be examined.
Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com>
Replace struct key's restrict_link function pointer with a pointer to
the new struct key_restriction. The structure contains pointers to the
restriction function as well as relevant data for evaluating the
restriction.
The garbage collector checks restrict_link->keytype when key types are
unregistered. Restrictions involving a removed key type are converted
to use restrict_link_reject so that restrictions cannot be removed by
unregistering key types.

Also unify/merge with the existing stuff.
I was a bit torn where to put this, but in the end I decided to put
all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we
have a bit a split with the other uapi related stuff used internally,
like drm_file.[hc], but I think overall this makes more sense.
If it's too confusing we can always add more cross-links to make it
more discoverable. But the auto-sprinkling of links kernel-doc already
does seems sufficient.
Also for prettier docs and more cross-links, switch the internal
defines over to an enum, as usual.

When a kretprobe is installed on a kernel function, there is a maximum
limit of how many calls in parallel it can catch (aka "maxactive"). A
kernel module could call register_kretprobe() and initialize maxactive
(see example in samples/kprobes/kretprobe_example.c).
But that is not exposed to userspace and it is currently not possible to
choose maxactive when writing to /sys/kernel/debug/tracing/kprobe_events
The default maxactive can be as low as 1 on single-core with a
non-preemptive kernel. This is too low and we need to increase it not
only for recursive functions, but for functions that sleep or resched.
This patch updates the format of the command that can be written to
kprobe_events so that maxactive can be optionally specified.
I need this for a bpf program attached to the kretprobe of
inet_csk_accept, which can sleep for a long time.
This patch includes a basic selftest:
> # ./ftracetest -v test.d/kprobe/
> === Ftrace unit tests ===
> [1] Kprobe dynamic event - adding and removing [PASS]
> [2] Kprobe dynamic event - busy event check [PASS]

word, meaning that userspace must always use the lower 5 bits to
communicate with the KVM device and must shift the value left by 3
places to obtain the actual priority mask level.
Since GICv3 supports the full 8 bits of priority masking in the ICH_VMCR,
we have to fix the value we export when emulating a GICv2 on top of a
hardware GICv3 and exporting the emulated GICv2 state to userspace.
Take the chance to clarify this aspect of the ABI.

This adds a new dynamic PMU to the Perf Events framework to program
and control the L3 cache PMUs in some Qualcomm Technologies SOCs.
The driver supports a distributed cache architecture where the overall
cache for a socket is comprised of multiple slices each with its own PMU.
Access to each individual PMU is provided even though all CPUs share all
the slices. User space needs to aggregate to individual counts to provide
a global picture.
The driver exports formatting and event information to sysfs so it can
be used by the perf user space tools with the syntaxes:
perf stat -a -e l3cache_0_0/read-miss/

The first argument to the restrict_link_func_t functions was a keyring
pointer. These functions are called by the key subsystem with this
argument set to the destination keyring, but restrict_link_by_signature
expects a pointer to the relevant trusted keyring.
Restrict functions may need something other than a single struct key
pointer to allow or reject key linkage, so the data used to make that
decision (such as the trust keyring) is moved to a new, fourth
argument. The first argument is now always the destination keyring.

Disable kasan after the first report. There are several reasons for
this:
- Single bug quite often has multiple invalid memory accesses causing
storm in the dmesg.
- Write OOB access might corrupt metadata so the next report will print
bogus alloc/free stacktraces.
- Reports after the first easily could be not bugs by itself but just
side effects of the first one.
Given that multiple reports usually only do harm, it makes sense to
disable kasan after the first one. If user wants to see all the
reports, the boot-time parameter kasan_multi_shot must be used.

The size of .word is the size of a word in the given platform, which
for intel systems is 16-bits but other architectures use different
sizes. However, .hword emits 16-bit numbers regardless of the
platform (and despite the name). The quantities specified in EDID are
platform independent, so they should work in spite of the default
target of the cc you are using, so use .hword where EDID specifies
16-bit numbers.

throtl_slice is important for blk-throttling. It's called slice
internally but it really is a time window blk-throttling samples data.
blk-throttling will make decision based on the samplings. An example is
bandwidth measurement. A cgroup's bandwidth is measured in the time
interval of throtl_slice.
A small throtl_slice meanse cgroups have smoother throughput but burn
more CPUs. It has 100ms default value, which is not appropriate for all
disks. A fast SSD can dispatch a lot of IOs in 100ms. This patch makes
it tunable.
Since throtl_slice isn't a time slice, the sysfs name
'throttle_sample_time' reflects its character better.

The i915 GVT team need the rc4 code to base some more code on.
Introduce a simple data structure for collecting correctable errors
along with accessors. More detailed description in the code itself.
The error decoding is done with the decoding chain now and
mce_first_notifier() gets to see the error first and the CEC decides
whether to log it and then the rest of the chain doesn't hear about it -
basically the main reason for the CE collector - or to continue running
the notifiers.
When the CEC hits the action threshold, it will try to soft-offine the
page containing the ECC and then the whole decoding chain gets to see
the error.

Commit 63c32ed4af ("dm raid: add raid4/5/6 journaling support") added

writethrough caching.
Introduce a "journal_mode" feature and use the new
r5c_journal_mode_set() API to add support for switching the journal
device's cache mode between write-through (the current default) and
write-back.
NOTE: If the journal device is not layered on resilent storage and it
fails, write-through mode will cause the "write hole" to reoccur. But
if the journal fails while in write-back mode it will cause data loss
for any dirty cache entries unless resilent storage is used for the
journal.

40GbE Intel Wired LAN Driver Updates 2017-03-23
This series contains updates to i40e and i40e.txt documentation.
Jake provides all the changes in the series which are centered around
ntuple filter fixes and additional support. Fixed the current
implementation of .set_rxnfc, where we were not reading the mask field
for filter entries which was resulting in filters not behaving as
expected and not working correctly. When cleaning up after disabling
flow director support, ensure that the default input set is correctly
reprogrammed. Since the hardware only supports a single input set for
all flows of that type, the driver shall only allow the input set to
change if there are no other configured filters for that flow type, so
add support to detect when we can update the input set for each flow
type. Align the driver to other drivers to partition the ring_cookie
value into 8bits of VF index, along with 32bits of queue number instead
of using the user-def field. Added support to parse the user-def field
into a data structure format to allow future extensions of the user-def
filed by keeping all the code that read/writes the field into a single
location. Added support for flexible payloads passed via ethtool
user-def field. We support a single flexible word (2byte) value per
protocol type, and we handle the FLX_PIT register using a list of
flexible entries so that each flow type may be configured separately.
Enabled flow director filters for SCTPv4 packets using the ethtool
ntuple interface to enable filters. Updated the documentation on the
i40e driver to include the newly added support to ntuple filters.
Reduced complexity of a if-continue-else-break section of code by
taking advantage of using hlist_for_each_entry_continue() instead.

Certain system process significant unconnected UDP workload.
It would be preferrable to disable UDP early demux for those systems
and enable it for TCP only.
By disabling UDP demux, we see these slight gains on an ARM64 system-
782 -> 788Mbps unconnected single stream UDPv4
633 -> 654Mbps unconnected UDPv4 different sources
The performance impact can change based on CPU architecure and cache
sizes. There will not much difference seen if entire UDP hash table
is in cache.
Both sysctls are enabled by default to preserve existing behavior.

suggested by Stephen.

Add optional "sector_size" parameter that specifies encryption sector
size (atomic unit of block device encryption).
Parameter can be in range 512 - 4096 bytes and must be power of two.
For compatibility reasons, the maximal IO must fit into the page limit,
so the limit is set to the minimal page size possible (4096 bytes).
NOTE: this device cannot yet be handled by cryptsetup if this parameter
is set.
IV for the sector is calculated from the 512 bytes sector offset unless
the iv_large_sectors option is used.
Test script using dmsetup:
DEV="/dev/sdb"
DEV_SIZE=$(blockdev --getsz $DEV)

For the new authenticated encryption we have to support generic composed
modes (combination of encryption algorithm and authenticator) because
this is how the kernel crypto API accesses such algorithms.
To simplify the interface, we accept an algorithm directly in crypto API
format. The new format is recognised by the "capi:" prefix. The
dmcrypt internal IV specification is the same as for the old format.
The crypto API cipher specifications format is:
capi:cipher_api_spec-ivmode[:ivopts]
Examples:
capi:cbc(aes)-essiv:sha256 (equivalent to old aes-cbc-essiv:sha256)
capi:xts(aes)-plain64 (equivalent to old aes-xts-plain64)
Examples of authenticated modes:
capi:gcm(aes)-random
capi:authenc(hmac(sha256),xts(aes))-random
capi:rfc7539(chacha20,poly1305)-random
Authenticated modes can only be configured using the new cipher format.
Note that this format allows user to specify arbitrary combinations that
can be insecure. (Policy decision is done in cryptsetup userspace.)
Authenticated encryption algorithms can be of two types, either native
modes (like GCM) that performs both encryption and authentication
internally, or composed modes where user can compose AEAD with separate
specification of encryption algorithm and authenticator.
For composed mode with HMAC (length-preserving encryption mode like an
XTS and HMAC as an authenticator) we have to calculate HMAC digest size
(the separate authentication key is the same size as the HMAC digest).
Introduce crypt_ctr_auth_cipher() to parse the crypto API string to get
HMAC algorithm and retrieve digest size from it.
Also, for HMAC composed mode we need to parse the crypto API string to
get the cipher mode nested in the specification. For native AEAD mode
(like GCM), we can use crypto_tfm_alg_name() API to get the cipher
specification.
Because the HMAC composed mode is not processed the same as the native
AEAD mode, the CRYPT_MODE_INTEGRITY_HMAC flag is no longer needed and
"hmac" specification for the table integrity argument is removed.

Allow the use of per-sector metadata, provided by the dm-integrity
module, for integrity protection and persistently stored per-sector
Initialization Vector (IV). The underlying device must support the
"DM-DIF-EXT-TAG" dm-integrity profile.
The per-bio integrity metadata is allocated by dm-crypt for every bio.

Both AEAD and HMAC protection authenticates not only data but also
sector metadata.
HMAC protection is implemented through autenc wrapper (so it is
processed the same way as an authenticated mode).
In HMAC mode there are two keys (concatenated in dm-crypt mapping
table). First is the encryption key and the second is the key for
authentication (HMAC). (It is userspace decision if these keys are
independent or somehow derived.)
The sector request for AEAD/HMAC authenticated encryption looks like this:
|----- AAD -------|------ DATA -------|-- AUTH TAG --|
| (authenticated) | (auth+encryption) | |
| sector_LE | IV | sector in/out | tag in/out |
For writes, the integrity fields are calculated during AEAD encryption
of every sector and stored in bio integrity fields and sent to
underlying dm-integrity target for storage.
For reads, the integrity metadata is verified during AEAD decryption of
every sector (they are filled in by dm-integrity, but the integrity
fields are pre-allocated in dm-crypt).
There is also an experimental support in cryptsetup utility for more
friendly configuration (part of LUKS2 format).
Because the integrity fields are not valid on initial creation, the
device must be "formatted". This can be done by direct-io writes to the
device (e.g. dd in direct-io mode). For now, there is available trivial
tool to do this, see: https://github.com/mbroz/dm_int_tools

The dm-integrity target emulates a block device that has additional
per-sector tags that can be used for storing integrity information.
A general problem with storing integrity tags with every sector is that
writing the sector and the integrity tag must be atomic - i.e. in case of
crash, either both sector and integrity tag or none of them is written.
To guarantee write atomicity the dm-integrity target uses a journal. It
writes sector data and integrity tags into a journal, commits the journal
and then copies the data and integrity tags to their respective location.
The dm-integrity target can be used with the dm-crypt target - in this
situation the dm-crypt target creates the integrity data and passes them
to the dm-integrity target via bio_integrity_payload attached to the bio.
In this mode, the dm-crypt and dm-integrity targets provide authenticated
disk encryption - if the attacker modifies the encrypted device, an I/O
error is returned instead of random data.
The dm-integrity target can also be used as a standalone target, in this
mode it calculates and verifies the integrity tag internally. In this
mode, the dm-integrity target can be used to detect silent data
corruption on the disk or in the I/O path.

This was missed in Tomeu's patch. Also remove the kerneldoc for the
internal function, we don't document that in general.
While at it word-smith the docs slightly for more clarity.

Just several fixups,
- fix page fault and vblank timeout issues due to delayed vblank handling.
- fix panel driver probing to fail without te-gpios property.
- fix potential security hole by using "%pK" format.
- fix wrong if statement condition.
And one cleanup which removes Exynos4415 SoC support which is not supported
anymore.
* 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos:
drm/exynos/dsi: make te-gpios optional

f_acm got an endianness fix by Oliver Neukum. This has been around for a
long time but it's finally fixed.
f_hid learned that it should never access hidg->req without first
grabbing the spinlock.
Roger Quadros fixed two bugs in the f_uvc function driver.
Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather
difficult to trigger. When we're dealing with bounced EP0 requests, we
should delay unmap until after ->complete() is called.
UDC class got a use-after-free fix.

The purpose of USB Type-C connector class is to provide
unified interface for the user space to get the status and
basic information about USB Type-C connectors on a system,
control over data role swapping, and when the port supports
USB Power Delivery, also control over power role swapping
and Alternate Modes.
