Javier González a4bd217b43 lightnvm: physical block device (pblk) target
This patch introduces pblk, a host-side translation layer for
Open-Channel SSDs to expose them like block devices. The translation
layer allows data placement decisions, and I/O scheduling to be
managed by the host, enabling users to optimize the SSD for their
specific workloads.

An open-channel SSD has a set of LUNs (parallel units) and a
collection of blocks. Each block can be read in any order, but
writes must be sequential. Writes may also fail, and if a block
requires it, must also be reset before new writes can be
applied.

To manage the constraints, pblk maintains a logical to
physical address (L2P) table,  write cache, garbage
collection logic, recovery scheme, and logic to rate-limit
user I/Os versus garbage collection I/Os.

The L2P table is fully-associative and manages sectors at a
4KB granularity. Pblk stores the L2P table in two places, in
the out-of-band area of the media and on the last page of a
line. In the cause of a power failure, pblk will perform a
scan to recover the L2P table.

The user data is organized into lines. A line is data
striped across blocks and LUNs. The lines enable the host to
reduce the amount of metadata to maintain besides the user
data and makes it easier to implement RAID or erasure coding
in the future.

pblk implements multi-tenant support and can be instantiated
multiple times on the same drive. Each instance owns a
portion of the SSD - both regarding I/O bandwidth and
capacity - providing I/O isolation for each case.

Finally, pblk also exposes a sysfs interface that allows
user-space to peek into the internals of pblk. The interface
is available at /dev/block/*/pblk/ where * is the block
device name exposed.

Laurent Pinchart 99bb078eee [media] v4l: Clearly document interactions between formats, controls and buffers
V4L2 exposes parameters that influence buffers sizes through the format
ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly
VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of
the format structure may also influence buffer sizes or buffer layout in
general. One existing such parameter is rotation, which is implemented
by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control
ioctls.

The interaction between those parameters and buffers is currently only
partially specified by the V4L2 API. In particular interactions between
controls and buffers isn't specified at all. The behaviour of the
VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is
also not fully specified.

This patch clearly defines and documents the interactions between
formats, selections, controls and buffers.

The preparatory discussions for the documentation change considered
completely disallowing controls that change the buffer size or layout,
in favour of extending the format API with a new ioctl that would bundle
those controls with format information. The idea has been rejected, as
this would essentially be a restricted version of the upcoming request
API that wouldn't bring any additional value.

Another option we have considered was to mandate the use of the request
API to modify controls that influence buffer size or layout. This has
also been rejected on the grounds that requiring the request API to
change rotation even when streaming is stopped would significantly
complicate implementation of drivers and usage of the V4L2 API for
applications.

Applications will however be required to use the upcoming request API to
change at runtime formats or controls that influence the buffer size or
layout, because of the need to synchronize buffers with the formats and
controls. Otherwise there would be no way to interpret the content of a
buffer correctly.

Omar Sandoval 00e043936e blk-mq: introduce Kyber multiqueue I/O scheduler
The Kyber I/O scheduler is an I/O scheduler for fast devices designed to
scale to multiple queues. Users configure only two knobs, the target
read and synchronous write latencies, and the scheduler tunes itself to
achieve that latency goal.

The implementation is based on "tokens", built on top of the scalable
bitmap library. Tokens serve as a mechanism for limiting requests. There
are two tiers of tokens: queueing tokens and dispatch tokens.

A queueing token is required to allocate a request. In fact, these
tokens are actually the blk-mq internal scheduler tags, but the
scheduler manages the allocation directly in order to implement its
policy.

Dispatch tokens are device-wide and split up into two scheduling
domains: reads vs. writes. Each hardware queue dispatches batches
round-robin between the scheduling domains as long as tokens are
available for that domain.

These tokens can be used as the mechanism to enable various policies.
The policy Kyber uses is inspired by active queue management techniques
for network routing, similar to blk-wbt. The scheduler monitors
latencies and scales the number of dispatch tokens accordingly. Queueing
tokens are used to prevent starvation of synchronous requests by
asynchronous requests.

Various extensions are possible, including better heuristics and ionice
support. The new scheduler isn't set as the default yet.

Akinobu Mita a9e9c7153e iio: adc: add max1117/max1118/max1119 ADC driver
This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver.

This new driver uses the zero length spi_transfers with the cs_change
flag set and/or the non-zero delay_usecs.

1. The zero length transfer with the spi_transfer.cs_change set is
required in order to select CH1.  The chip select line must be brought
high and low again without transfer.

2. The zero length transfer with the spi_transfer.delay_usecs > 0 is
required for waiting the conversion to be complete.  The conversion
begins with the falling edge of the chip select.  During the conversion
process, SCLK is ignored.

These two usages are unusual.  But the spi controller drivers that use
a default implementation of transfer_one_message() are likely to work.
(I've tested this adc driver with spi-omap2-mcspi and spi-xilinx)

On the other hand, some spi controller drivers that have their own
transfer_one_message() may not work.  But at least for the zero length
transfer with delay_usecs > 0, I'm proposing a new testcase for the
spi-loopback-test that can test whether the delay_usecs setting has
taken effect.

encoder that can counts up/down depending of the levels and edges
of the selected external pins.

This patch allow to read/write the counter, get it direction,
set/get quadrature modes and get scale factor.

When counting up preset value is the limit of the counter.
When counting down the counter start from preset value down to 0.
This preset value could be set/get by using
/sys/bus/iio/devices/iio:deviceX/in_count0_preset attribute.

Stefan Agner 8566f70c8a rtc: ds1307: support m41t0 variant
The m41t0 variant is very similar to the already supported m41t00
variant, with the notable exception of the oscillator fail bit.
The data sheet notes:

  If the oscillator fail (OF) bit is internally set to a '1,' this
  indicates that the oscillator has either stopped, or was stopped
  for some period of time and can be used to judge the validity of
  the clock and date data.

The bit will get cleared with a regular write of the system time,
so no changes are needed to clear it.

Matthew R. Ochs 8fa4f1770d scsi: cxlflash: Remove port configuration assumptions
At present, the cxlflash driver only supports hardware with two FC ports. The
code was initially designed with this assumption and is dependent on having
two FC ports - adding more ports will break logic within the driver.

To mitigate this issue, remove the existing port assumptions and transition
the code to support more than two ports. As a side effect, clarify the
interpretation of the DK_CXLFLASH_ALL_PORTS_ACTIVE flag.

Michal Hocko ffc10d82ff ACPI / scan: Drop support for force_remove
/sys/firmware/acpi/hotplug/force_remove was presumably added to support
auto offlining in the past. This is, however, inherently dangerous for
some hotplugable resources like memory. The memory offlining fails when
the memory is still in use and cannot be dropped or migrated. If we
ignore the failure we are basically allowing for subtle memory
corruption or a crash.

We have actually noticed the later while hitting BUG() during the memory
hotremove (remove_memory):
	ret = walk_memory_range(PFN_DOWN(start), PFN_UP(start + size - 1), NULL,
			check_memblock_offlined_cb);
	if (ret)
		BUG();

it took us quite non-trivial time realize that the customer had
force_remove enabled. Even if the BUG was removed here and we could
propagate the error up the call chain it wouldn't help at all because
then we would hit a crash or a memory corruption later and harder to
debug. So force_remove is unfixable for the memory hotremove. We haven't
checked other hotplugable resources to be prone to a similar problems.

Remove the force_remove functionality because it is not fixable currently.
Keep the sysfs file and report an error if somebody tries to enable it.
Encourage users to report about the missing functionality and work with
them with an alternative solution.

In the following example, if MAX is defined to be 1, then the compiler
knows (Q % MAX) is equal to zero.  The compiler can therefore throw
away the "then" branch (and the "if"), retaining only the "else" branch.

	q = READ_ONCE(a);
	if (q % MAX) {
		WRITE_ONCE(b, 1);
		do_something();
	} else {
		WRITE_ONCE(b, 2);
		do_something_else();
	}

It is therefore necessary to modify the example like this:

        q = READ_ONCE(a);
-       WRITE_ONCE(b, 1);
+       WRITE_ONCE(b, 2);

Michalis Kokologiannakis 93728af0a1 doc: Update the comparisons rule in rcu_dereference.txt
When an RCU-protected pointer is fetched but never dereferenced
rcu_access_pointer() should be used in place of rcu_dereference().
This commit explicitly records this very fact in Documentation/
RCU/rcu_dereference.txt, in order to prevent the usage of
rcu_dereference() in comparisons.

Paul E. McKenney 6771853bce doc: Update requirements based on recent changes
These changes include lighter-weight expedited grace periods, the fact
that expedited grace periods and rcu_barrier() no longer block CPU
hotplug, some HTML font fixups, noting that rcu_barrier() need not wait
for a grace period (even if callbacks are posted), the fact that SRCU
read-side critical sections can be used from offline CPUs, and the fact
that SRCU now maintains per-CPU callback lists.

Paul E. McKenney b4553f0cfe doc: Add mid-boot operation to expedited grace periods
This commit adds a description of how expedited grace periods operate
during the mid-boot "dead zone", which starts when the scheduler spawns
the first kthread and ends when all of RCU's kthreads have been spawned.
In short, before mid-boot, synchronous grace periods can be a no-op.
After the end of mid-boot, workqueues may be used.  During mid-boot,
the requesting task drivees the expedited grace period.

Laxman Dewangan 0dafdd168b pwm: tegra: Add DT binding details to configure pin in suspends/resume
In some of NVIDIA Tegra's platform, PWM controller is used to
control the PWM controlled regulators. PWM signal is connected to
the VID pin of the regulator where duty cycle of PWM signal decide
the voltage level of the regulator output.

When system enters suspend, some PWM client/slave regulator devices
require the PWM output to be tristated.

Add DT binding details to provide the pin configuration state
from PWM and pinctrl DT node in suspend and active state of
the system.

Mauro Carvalho Chehab 67cc20e008 writing_musb_glue_layer.rst: Enrich its ReST representation
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
at the text.

Jacopo Mondi 8c58f1a7a4 pinctrl: generic: Add bi-directional and output-enable
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.

Yoshihiro Shimoda cc995c9ec1 usb: gadget: udc: renesas_usb3: add support for usb role swap
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

Fabio Estevam 570c70a60f ASoC: sgtl5000: Allow LRCLK pad drive strength to be changed
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
LRCLK pin with the scope the swap did not happen. After removing
the probe the swap started to happen again.

After changing the LRCLK pad drive strength to the maximum value the
issue is gone.

Same fix works on a mx6dl Colibri board as well.

Jiri Olsa 4ffa3c977b x86/intel_rdt: Add cpus_list rdtgroup file
The resource control filesystem provides only a bitmask based cpus file for
assigning CPUs to a resource group. That's cumbersome with large cpumasks
and non-intuitive when modifying the file from the command line.

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

Add 'cpus_list' file which is CPU range based.

  # cd /sys/fs/resctrl/
  # echo 1-10 > krava/cpus_list
  # cat krava/cpus_list
  1-10
  # cat krava/cpus
  0007fe

 to monitor the state change of all supported external connectors
 from the extcon device by using only one notifier_block.

 				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

Meng Dongyang e3462f9e07 dt-bindings: phy-rockchip-inno-usb2: add assign clock property in usb2-phy node
On some platform such as RK3328, the 480m clock may need to assign
clock parent in dts in stead of clock driver. So this patch add
property of assigned-clocks and assigned-clock-parents to assign
parent for 480m clock.

Icenowy Zheng a0b1910e85 dt: bindings: add pmu0 regs for USB PHYs on Allwinner H3/V3s/A64
Allwinner H3/V3s/A64 SoCs have a special USB PHY0 that can route to two
controllers: one is MUSB and the other is a EHCI/OHCI pair.

When it's routed to EHCI/OHCI pair, it will needs a "pmu0" regs to
tweak, like other EHCI/OHCI pairs in Allwinner SoCs.

Add this to the binding of USB PHYs on Allwinner H3/V3s/A64.

Alexander Graf 3fe17e6826 KVM: arm/arm64: Add ARM user space interrupt signaling ABI
We have 2 modes for dealing with interrupts in the ARM world. We can
either handle them all using hardware acceleration through the vgic or
we can emulate a gic in user space and only drive CPU IRQ pins from
there.

Unfortunately, when driving IRQs from user space, we never tell user
space about events from devices emulated inside the kernel, which may
result in interrupt line state changes, so we lose out on for example
timer and PMU events if we run with user space gic emulation.

Define an ABI to publish such device output levels to userspace.

Linus Walleij 96b3c83303 iio: xoadc: augment DT bindings a bit
In order to accommodate in a logical manner for the premuxed channels
in PM8921 and the similarly addressed channels in later PMICs, we
need a twocell arrangement with premux and analog mux setting as
a tuple to uniquely identify a hardware channel.

These bindings are not yet in use, so it should be fine to augment
them before we actually start using it in drivers and device trees.

This scheme came out of lengthy discussions and reverse-engineering
and reading of the few information sources we have.

contains address definitions for the coreboot table (a list of
variable-sized descriptors providing information about various compile-
and run-time generated firmware parameters) and the CBMEM area (the
structure containing most run-time resident memory regions set up by
coreboot).

These definitions allow kernel drivers to easily access data contained
in and pointed to by these regions (such as coreboot's in-memory log).

Linus Walleij bb0c6bb3b7 clocksource: Augment bindings for Faraday timer
It turns out that the Cortina Gemini timer block is just a
standard IP block from Faraday Technology named FTTMR010.

In order to make things clear and understandable, we rename the
bindings with a Faraday compatible as primary and the Cortina
gemini as a more specific case.

For the plain Faraday timer we require two clock references,
while the Gemini can keep it's syscon lookup pattern.

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.

Tony Lindgren 6118714275 pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()
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")

Will Deacon fccb4e3b8a iommu: Allow default domain type to be set on the kernel command line
The IOMMU core currently initialises the default domain for each group
to IOMMU_DOMAIN_DMA, under the assumption that devices will use
IOMMU-backed DMA ops by default. However, in some cases it is desirable
for the DMA ops to bypass the IOMMU for performance reasons, reserving
use of translation for subsystems such as VFIO that require it for
enforcing device isolation.

Rather than modify each IOMMU driver to provide different semantics for
DMA domains, instead we introduce a command line parameter that can be
used to change the type of the default domain. Passthrough can then be
specified using "iommu.passthrough=1" on the kernel command line.

The current SMR masking support using a 2-cell iommu-specifier is
primarily intended to handle individual masters with large and/or
complex Stream ID assignments; it quickly gets a bit clunky in other SMR
use-cases where we just want to consistently mask out the same part of
every Stream ID (e.g. for MMU-500 configurations where the appended TBU
number gets in the way unnecessarily). Let's add a new property to allow
a single global mask value to better fit the latter situation.

 following VZ / guest hardware features:
 - MIPS32 and MIPS64, r5 (VZ requires r5 or later) and r6
 - TLBs with GuestID (IMG cores) or Root ASID Dealias (Octeon III)
 - Shared physical root/guest TLB (IMG cores)
 - FPU / MSA
 - Cop0 timer (up to 1GHz for now due to soft timer limit)
 - Segmentation control (EVA)
 - Hardware page table walker (HTW) both for root and guest TLB
 
 Also included is a proper implementation of the TLBR instruction for the
 trap & emulate MIPS KVM implementation.
 
 Preliminary MIPS architecture changes are applied directly with Ralf's
 ack.

Merge tag 'kvm_mips_4.12_1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/kvm-mips

From: James Hogan <james.hogan@imgtec.com>

KVM: MIPS: VZ support, Octeon III, and TLBR

Add basic support for the MIPS Virtualization Module (generally known as
MIPS VZ) in KVM. We primarily support the ImgTec P5600, P6600, I6400,
and Cavium Octeon III cores so far. Support is included for the
following VZ / guest hardware features:
- MIPS32 and MIPS64, r5 (VZ requires r5 or later) and r6
- TLBs with GuestID (IMG cores) or Root ASID Dealias (Octeon III)
- Shared physical root/guest TLB (IMG cores)
- FPU / MSA
- Cop0 timer (up to 1GHz for now due to soft timer limit)
- Segmentation control (EVA)
- Hardware page table walker (HTW) both for root and guest TLB

Also included is a proper implementation of the TLBR instruction for the
trap & emulate MIPS KVM implementation.

Preliminary MIPS architecture changes are applied directly with Ralf's
ack.

Yi Min Zhao a892095013 KVM: s390: introduce adapter interrupt inject function
Inject adapter interrupts on a specified adapter which allows to
retrieve the adapter flags, e.g. if the adapter is subject to AIS
facility or not. And add documentation for this interface.

For adapters subject to AIS, handle the airq injection suppression
for a given ISC according to the interruption mode:
- before injection, if NO-Interruptions Mode, just return 0 and
  suppress, otherwise, allow the injection.
- after injection, if SINGLE-Interruption Mode, change it to
  NO-Interruptions Mode to suppress the following interrupts.

Besides, add tracepoint for suppressed airq and AIS mode transitions.

Fei Li 5197839354 KVM: s390: introduce ais mode modify function
Provide an interface for userspace to modify AIS
(adapter-interruption-suppression) mode state, and add documentation
for the interface. Allowed target modes are ALL-Interruptions mode
and SINGLE-Interruption mode.

We introduce the 'simm' and 'nimm' fields in kvm_s390_float_interrupt
to store interruption modes for each ISC. Each bit in 'simm' and
'nimm' targets to one ISC, and collaboratively indicate three modes:
ALL-Interruptions, SINGLE-Interruption and NO-Interruptions. This
interface can initiate most transitions between the states; transition
from SINGLE-Interruption to NO-Interruptions via adapter interrupt
injection will be introduced in a following patch. The meaningful
combinations are as follows:

    interruption mode | simm bit | nimm bit
    ------------------|----------|----------
             ALL      |    0     |     0
           SINGLE     |    1     |     0
             NO       |    1     |     1

Besides, add tracepoint to track AIS mode transitions.

In order to properly implement adapter-interruption suppression, we
need a way for userspace to specify which adapters are subject to
suppression. Let's convert the existing (and unused) 'pad' field into
a 'flags' field and define a flag value for suppressible adapters.

Besides, add documentation for the interface.

Marek Szyprowski 60641e2259 [media] s5p-mfc: Use preallocated block allocator always for MFC v6+
It turned out that all versions of MFC v6+ hardware doesn't have a strict
requirement for ALL buffers to be allocated on higher addresses than the
firmware base like it was documented for MFC v5. This requirement is true
only for the device and per-context buffers. All video data buffers can be
allocated anywhere for all MFC v6+ versions. Basing on this fact, the
special DMA configuration based on two reserved memory regions is not
really needed for MFC v6+ devices, because the memory requirements for the
firmware, device and per-context buffers can be fulfilled by the simple
probe-time pre-allocated block allocator introduced in previous patch.

This patch enables support for such pre-allocated block based allocator
always for MFC v6+ devices. Due to the limitations of the memory management
subsystem the largest supported size of the pre-allocated buffer when no
CMA (Contiguous Memory Allocator) is enabled is 4 MiB.

This patch also removes the requirement to provide two reserved memory
regions for MFC v6+ devices in device tree. Now the driver is fully
functional without them.

Tony Luck c4026b7b95 x86/intel_rdt: Implement "update" mode when writing schemata file
The schemata file can have multiple lines and it is cumbersome to update
all lines.

Remove code that requires that the user provides values for every resource
(in the right order).  If the user provides values for just a few
resources, update them and leave the rest unchanged.

Side benefit: we now check which values were updated and only send IPIs to
cpus that actually have updates.

Stephan Mueller f1c316a3ab KEYS: add SP800-56A KDF support for DH
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.

Mat Martineau 6563c91fd6 KEYS: Add KEYCTL_RESTRICT_KEYRING
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.

The restrict_link functions used to validate keys as they are linked

that the requested keys can be examined.

restriction.

The garbage collector checks restrict_link->keytype when key types are

to use restrict_link_reject so that restrictions cannot be removed by
unregistering key types.

Daniel Vetter 2640981f36 drm: document drm_ioctl.[hc]
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.

v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a
bit more drive-by polish.

v3: Fix typo, spotted by xerpi on irc (Sergi).

v4: Add missing space in comment (Neil).

Alban Crequy 696ced4fb1 tracing/kprobes: expose maxactive for kretprobe in kprobe_events
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]

Alexandre Courbot bf594a896c dt-bindings: Add documentation for GP10B GPU
GP10B's definition is mostly similar to GK20A's and GM20B's. The only
noticeable difference is the use of power domains instead of a regulator
for power supply.

Christoffer Dall 6d56111c92 KVM: arm/arm64: vgic: Fix GICC_PMR uaccess on GICv3 and clarify ABI
As an oversight, for GICv2, we accidentally export the GICC_PMR register
in the format of the GICH_VMCR.VMPriMask field in the lower 5 bits of a
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.

Agustin Vega-Frias 3071f13d75 perf: qcom: Add L3 cache PMU driver
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/
   perf stat -a -e l3cache_0_0/event=0x21/

Mat Martineau aaf66c8838 KEYS: Split role of the keyring pointer for keyring restrict functions
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.

The QoS IP does not accept AVB capabilities to default/queue 0, this way we
guarantee 75% bandwidth for AVB. This patch assures that only queues >= 1

Jonathan Cameron 0c8f492dd7 iio:imu:mpu6050 add explicit mpu9250 support
The mpu9250 is a SIP containing an mpu6500 and an ak8975.  If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.

However, the WHOAMI value changes as well so best to add explicit support.

These bindings are somewhat lagging the state of the driver.  The i2c-gate

Mark Rutland b0845ce583 kasan: report only the first error by default
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.

Arnd Bergmann 9720a9a31d Rockchip dts changes based on the newly created arm/arm64 symlinks.
The core addition is the support for the rk3399-based Gru family of
 ChromeOS devices, like the Kevin board which is the recently released
 Samsung Chromebook Plus. Additionally the usb3 controllers are added
 to rk3399 as they're used on Gru devices and even without full type-c
 support they can at least drive usb2 devices already.

Tony Lindgren 25ec249632 iio: adc: cpcap: Add minimal support for CPCAP PMIC ADC
On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.

Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.

Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.

Javi Merino bd283d2f66 drm: use .hword to represent 16-bit numbers
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.
