Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1. And it's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree, I'll follow up with fixes for those after this gets merged.

USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to the Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task. All of these have been in linux-next for a while with no reported issues.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull livepatch updates from Jiri Kosina: - a per-task consistency model is being added for architectures that support reliable stack dumping (extending this, currently rather trivial set, is currently in the works). This extends the nature of the types of patches that can be applied by live patching infrastructure. The code stems from the design proposal made [1] back in November 2014. It's a hybrid of SUSE's kGraft and RH's kpatch, combining advantages of both: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible. Most of the heavy lifting done by Josh Poimboeuf with help from Miroslav Benes and Petr Mladek [1] https://lkml.kernel.org/r/20141107140458.GA21774@suse.cz - module load time patch optimization from Zhou Chengming - a few assorted small fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching: livepatch: add missing printk newlines livepatch: Cancel transition a safe way for immediate patches livepatch: Reduce the time of finding module symbols livepatch: make klp_mutex proper part of API livepatch: allow removal of a disabled patch livepatch: add /proc/<pid>/patch_state livepatch: change to a per-task consistency model livepatch: store function sizes livepatch: use kstrtobool() in enabled_store() livepatch: move patching functions into patch.c livepatch: remove unnecessary object loaded check livepatch: separate enabled and patched states livepatch/s390: add TIF_PATCH_PENDING thread flag livepatch/s390: reorganize TIF thread flag bits livepatch/powerpc: add TIF_PATCH_PENDING thread flag livepatch/x86: add TIF_PATCH_PENDING thread flag livepatch: create temporary klp_update_patch_state() stub x86/entry: define _TIF_ALLWORK_MASK flags explicitly stacktrace/x86: add function for detecting reliable stack traces |

ACPI updates for v4.12-rc1
- Update the core device enumeration code to make it more internally
consistent and robust and drop the force_remove sysfs attribute
that could be used to tell it to ignore errors on device
hot-removal which was dangerous in general and no real and
still relevant use cases for it could be found (Rafael Wysocki,
Michal Hocko).
- Make the core device enumeration code use _PXM to associate
platform devices created by it with specific NUMA nodes (Shanker
Donthineni).
- Extend the CPPC library by adding more sysfs entries for
performance capabilities to it and making it use the lowest
nonlinear performance parameter (Prashanth Prakash).
- Make the CPU online more consistent with CPU initialization in
the ACPI processor driver (Prashanth Prakash).
- Update the AC and battery drivers to help them avoid attaching to
devices that cannot be handled by them and update the axp288_charger
power supply driver to work correctly on ACPI systems without the
INT3496 device (Hans de Goede).
- Add an ACPI operation region driver for the Intel CHT Whiskey Cove
PMIC and update the xpower operation region driver to work without
IIO which isn't really necessary for it to work (Hans de Goede).
- Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist
(Kai Heng Feng).
- Make the code in the ACPI video driver easier to follow by adding
symbols and comments to it (Dmitry Frank).
- Update ACPI documentation and drop a function that has no users
from the tables-handling code (Cao jin, Baoquan He).

PCI: Add sysfs sriov_drivers_autoprobe to control VF driver binding
Sometimes it is not desirable to bind SR-IOV VFs to drivers. This can save host side resource usage by VF instances that will be assigned to VMs. Add a new PCI sysfs interface "sriov_drivers_autoprobe" to control that from the PF. To modify it, echo 0/n/N (disable probe) or 1/y/Y (enable probe) to: /sys/bus/pci/devices/<DOMAIN:BUS:DEVICE.FUNCTION>/sriov_drivers_autoprobe Note that this must be done before enabling VFs. The change will not take effect if VFs are already enabled. Simply, one can disable VFs by setting sriov_numvfs to 0, choose whether to probe or not, and then re-enable the VFs by restoring sriov_numvfs.

The attribute 'role' is used to switch host/gadget role dynamically, the uewr can read the current role, and write the other role compare to current one to finish the switch.

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.

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 Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

livepatch: change to a per-task consistency model
Change livepatch to use a basic per-task consistency model. This is the
foundation which will eventually enable us to patch those ~10% of
security patches which change function or data semantics. This is the
biggest remaining piece needed to make livepatch more generally useful.
This code stems from the design proposal made by Vojtech [1] in November
2014. It's a hybrid of kGraft and kpatch: it uses kGraft's per-task
consistency and syscall barrier switching combined with kpatch's stack
trace switching. There are also a number of fallback options which make
it quite flexible.
Patches are applied on a per-task basis, when the task is deemed safe to
switch over. When a patch is enabled, livepatch enters into a
transition state where tasks are converging to the patched state.
Usually this transition state can complete in a few seconds. The same
sequence occurs when a patch is disabled, except the tasks converge from
the patched state to the unpatched state.
An interrupt handler inherits the patched state of the task it
interrupts. The same is true for forked tasks: the child inherits the
patched state of the parent.
Livepatch uses several complementary approaches to determine when it's
safe to patch tasks:
1. The first and most effective approach is stack checking of sleeping
tasks. If no affected functions are on the stack of a given task,
the task is patched. In most cases this will patch most or all of
the tasks on the first try. Otherwise it'll keep trying
periodically. This option is only available if the architecture has
reliable stacks (HAVE_RELIABLE_STACKTRACE).
2. The second approach, if needed, is kernel exit switching. A
task is switched when it returns to user space from a system call, a
user space IRQ, or a signal. It's useful in the following cases:
a) Patching I/O-bound user tasks which are sleeping on an affected
function. In this case you have to send SIGSTOP and SIGCONT to
force it to exit the kernel and be patched.
b) Patching CPU-bound user tasks. If the task is highly CPU-bound
then it will get patched the next time it gets interrupted by an
IRQ.
c) In the future it could be useful for applying patches for
architectures which don't yet have HAVE_RELIABLE_STACKTRACE. In
this case you would have to signal most of the tasks on the
system. However this isn't supported yet because there's
currently no way to patch kthreads without
HAVE_RELIABLE_STACKTRACE.
3. For idle "swapper" tasks, since they don't ever exit the kernel, they
instead have a klp_update_patch_state() call in the idle loop which
allows them to be patched before the CPU enters the idle state.
(Note there's not yet such an approach for kthreads.)
All the above approaches may be skipped by setting the 'immediate' flag
in the 'klp_patch' struct, which will disable per-task consistency and
patch all tasks immediately. This can be useful if the patch doesn't
change any function or data semantics. Note that, even with this flag
set, it's possible that some tasks may still be running with an old
version of the function, until that function returns.
There's also an 'immediate' flag in the 'klp_func' struct which allows
you to specify that certain functions in the patch can be applied
without per-task consistency. This might be useful if you want to patch
a common function like schedule(), and the function change doesn't need
consistency but the rest of the patch does.
For architectures which don't have HAVE_RELIABLE_STACKTRACE, the user
must set patch->immediate which causes all tasks to be patched
immediately. This option should be used with care, only when the patch
doesn't change any function or data semantics.
In the future, architectures which don't have HAVE_RELIABLE_STACKTRACE
may be allowed to use per-task consistency if we can come up with
another way to patch kthreads.
The /sys/kernel/livepatch/<patch>/transition file shows whether a patch
is in transition. Only a single patch (the topmost patch on the stack)
can be in transition at a given time. A patch can remain in transition
indefinitely, if any of the tasks are stuck in the initial patch state.
A transition can be reversed and effectively canceled by writing the
opposite value to the /sys/kernel/livepatch/<patch>/enabled file while
the transition is in progress. Then all the tasks will attempt to
converge back to the original patch state.

* spear adc. It's not perfect and there are some datasheet disagreements, but
it works and is good enough to graduate.
New features
* documentation
- abi docs for in_proximity_sampling_frequency_available.
- generalise counting direction ABI docs as a second driver is going to
use them.
* hid-sensor-prox
- Add support for HID_USAGE_SENSOR_HUMAN_PRESENCE if used on a particular
device.

zram: remove obsolete sysfs attrs
We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.

IB/cma: Add default RoCE TOS to CMA configfs
Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

rtc: bq32000: add support to enable disable the trickle charge FET bypass
The bq32000 includes a trickle charge circuit to maintain the charge of the backup supply when a super capacitor is used. You can enable the charging circuit by setting 'trickle-resistor-ohms', additionally you can set TCFE to 1 to bypass the internal diode and boost the charge voltage of the backup supply. You might want to enable/disable the TCFE switch from userspace (e.g when device is only connected to a battery) This patch introduces a new sysfs entry to enable and disable this FET form userspace.

PM / devfreq: Simplify the sysfs name of devfreq-event device
This patch just removes '.' character from the sysfs name of devfreq-event
device as following. Usually, the subsystem uses the similiar naming style
such as {framework name}{Number}.
- old : /sys/class/devfreq-event/event.(X)
- new : /sys/class/devfreq-event/event(X)
And this patch initializes the value of 'event_no' with -1
in order to remove the unneeded operation (-1) when calling
the atomic_inc_return(&event_no).
Lastly, this patch adds the ABI document for devfreq-event class.

[media] rc: change wakeup_protocols to list all protocol variants
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

leds: class: Add new optional brightness_hw_changed attribute
Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

iio: Add STM32 timer trigger driver
Timers IPs can be used to generate triggers for other IPs like DAC or ADC. Each trigger may result of timer internals signals like counter enable, reset or edge, this configuration could be done through "master_mode" device attribute. Since triggers could be used by DAC or ADC their names are defined in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger function could be used to check if the trigger is valid or not. "trgo" trigger have a "sampling_frequency" attribute which allow to configure timer sampling frequency. version 8: - change kernel version from 4.10 to 4.11 in ABI documentation version 7: - remove all iio_device related code - move driver into trigger directory version 5: - simplify tables of triggers - only create an IIO device when needed version 4: - get triggers configuration from "reg" in DT - add tables of triggers - sampling frequency is enable/disable when writing in trigger sampling_frequency attribute - no more use of interruptions version 3: - change compatible to "st,stm32-timer-trigger" - fix attributes access right - use string instead of int for master_mode and slave_mode - document device attributes in sysfs-bus-iio-timer-stm32 version 2: - keep only one compatible - use st,input-triggers-names and st,output-triggers-names to know which triggers are accepted and/or create by the device Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> |

First round of new device support, features and cleanups for IIO in the 4.11 cycle.
It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * |

Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner:
"This provides support for Intel's Cache Allocation Technology, a cache
partitioning mechanism.
The interface is odd, but the hardware interface of that CAT stuff is
odd as well.
We tried hard to come up with an abstraction, but that only allows
rather simple partitioning, but no way of sharing and dealing with the
per package nature of this mechanism.
In the end we decided to expose the allocation bitmaps directly so all
combinations of the hardware can be utilized.
There are two ways of associating a cache partition:
- Task
A task can be added to a resource group. It uses the cache
partition associated to the group.
- CPU
All tasks which are not member of a resource group use the group to
which the CPU they are running on is associated with.
That allows for simple CPU based partitioning schemes.
The main expected user sare:
- Virtualization so a VM can only trash only the associated part of
the cash w/o disturbing others
- Real-Time systems to seperate RT and general workloads.
- Latency sensitive enterprise workloads
- In theory this also can be used to protect against cache side
channel attacks"
[ Intel RDT is "Resource Director Technology". The interface really is
rather odd and very specific, which delayed this pull request while I
was thinking about it. The pull request itself came in early during
the merge window, I just delayed it until things had calmed down and I
had more time.
But people tell me they'll use this, and the good news is that it is
_so_ specific that it's rather independent of anything else, and no
user is going to depend on the interface since it's pretty rare. So if

sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work
and quite a lot of cleanups and improvements to existing code have
been done. The rest are usual stuff, a few HD-audio and USB-audio
quirks and fixes, as well as the drop of kthread usages in the whole
subsystem.
Below are some highlights:
ASoC:
- Support for stereo DAPM controls
- Some initial work on the of-graph sound card
- regmap conversions of the remaining AC'97 drivers
- A new version of the topology ABI; this should be backward compatible
- Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
Intel skylake, atom-sst
- New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
Realtek RT5665
USB-audio:
- Yet another race fix at disconnection
- Tolerated packet size calculation for some Android devices
- Quirks for Axe-Fx II, QuickCam, TEAC 501/503
HD-audio:
- Improvement of Dell pin fixup mapping
- Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
Misc:
- Replace all kthread usages with simple works

Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1. Big thing here is the nice addition of "functional dependencies" to the driver core. The idea has been talked about for a very long time, great job to Rafael for stepping up and implementing it. It's been tested for longer than the 4.9-rc1 date, we held off on merging it earlier in order to feel more comfortable about it. Other than that, it's just a handful of small other patches, some good cleanups to the mess that is the firmware class code, and we have a test driver for the deferred probe logic.

Staging/IIO patches for 4.10-rc1
Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev
tree), and some iio drivers were also dropped, but I think we ended up
adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands
out at all.
All of these have been in linux-next for a while. There will be a merge
conflict with Al's vfs tree in the lustre code, but the resolution for
that should be pretty simple, that too has been in linux-next.

Pull power management updates from Rafael Wysocki:
"Again, cpufreq gets more changes than the other parts this time (one
new driver, one old driver less, a bunch of enhancements of the
existing code, new CPU IDs, fixes, cleanups)
There also are some changes in cpuidle (idle injection rework, a
couple of new CPU IDs, online/offline rework in intel_idle, fixes and
cleanups), in the generic power domains framework (mostly related to
supporting power domains containing CPUs), and in the Operating
Performance Points (OPP) library (mostly related to supporting devices
with multiple voltage regulators)
In addition to that, the system sleep state selection interface is
modified to make it easier for distributions with unchanged user space
to support suspend-to-idle as the default system suspend method, some
issues are fixed in the PM core, the latency tolerance PM QoS
framework is improved a bit, the Intel RAPL power capping driver is
cleaned up and there are some fixes and cleanups in the devfreq
subsystem

Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.
- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.
- Support for WRITE_ZEROES from Chaitanya.
- Lightnvm updates from Javier/Matias.
- Supoort for FC for the nvme-over-fabrics code. From James Smart.
- A bunch of fixes from a whole slew of people, too many to name
here"

VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing
this virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a
portion of a physical GPU. QEMU composes these mdevs into PCI
representations using the existing VFIO user API. This enables
both Intel KVM-GT support, which is also expected to arrive into
Linux mainline during the v4.10 merge window, as well as NVIDIA
vGPU, and also Channel I/O devices (aka CCW devices) for s390
virtualization support. (Kirti Wankhede, Neo Jia)
- Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
- Fixes to VFIO capability chain handling (Eric Auger)
- Error handling fixes for fallout from mdev (Christophe JAILLET)
- Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)

remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. Handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation. This ensures that all vrings for all virtio devices are allocated before we boot the remote processor. The debugfs mechanism for starting and stopping remoteproc instances was replaced with a sysfs interface, also providing a mechanism for specifying firmware to use by the instance. This allows user space to load and boot use case specific firmware on remote processors. New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as removal of the unused StE modem loader. Finally support for crash recovery in the Qualcomm Wirelss subsystem (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes and cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJYTzfjAAoJEAsfOT8Nma3Fcs0P/irQd7U3gW14XFnl4ObdCOSO WlfG6jYP3fkWYA/ynxmu1FbRsyjP1aCrTRmW7oUGtTjCey8oUj69jo2+nLm0yx1k EtaTM+72hc7wULaGCBVvmA+LdQRRmTof9uJEjKvDyC8FAY0Thyvu77qlXQ5BrJkN o9xNVPDne/1RZx8vVI/zGEeL5+pNK1LXVy0vtFdG89acimu8yIJWJGS0IabnEWLs 8US6kpxROwkLefuTD4Rs4ByL6S5+1pHwVM6L/5GxsMawMzOhvzYgRa0SNNh7cNO/ e5ND7dUTcCt7lMOnpbSfqm2BbVRky6ATsoYrOdnVEH9sYJkQ9pMONadHIlVZFwce YVDp0UwEasf2IMtAFlvxDI31C5Wm8lpYOL7eixkkVrI1DJaBj8+Ih38F2IruWl9R QeDSFH/8a9l6fyN6RIUuPR8b1eeurl+CDoYWKEN6vzXDSi8GqsElB70xIAN/Umdq wdJvJByfitYLKEHenG5+mnQrDTQJ0C2f45hynkTCfJY1Qdl6nsMQi5sZFrE8HpOs dXFnpg/YK98wWmjyADEYDziH2y5oMHM6r5uljjcKOJDnzwLsDh8WQqhH4dNPNZBA 2+b4ouhbJLwYMM3zpem8JvV0rIsXvn3Kc8VNKcWOtHymkn8hLQ6Zexsr+RkbttQL Em5DvXL5lPm7wVYHvgP8 =/1kU -----END PGP SIGNATURE----- Merge tag 'rproc-v4.10' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: - introduce remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. - handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation.

These are the documentation changes for 4.10.
It's another busy cycle for the docs tree, as the sphinx conversion
continues. Highlights include:
- Further work on PDF output, which remains a bit of a pain but should be
more solid now.
- Five more DocBook template files converted to Sphinx. Only 27 to go...
Lots of plain-text files have also been converted and integrated.
- Images in binary formats have been replaced with more source-friendly
versions.
- Various bits of organizational work, including the renaming of various
files discussed at the kernel summit.
- New documentation for the device_link mechanism.
...and, of course, lots of typo fixes and small updates.

block: add support for REQ_OP_WRITE_ZEROES
This adds a new block layer operation to zero out a range of LBAs. This allows to implement zeroing for devices that don't use either discard with a predictable zero pattern or WRITE SAME of zeroes. The prominent example of that is NVMe with the Write Zeroes command, but in the future, this should also help with improving the way zeroing discards work. For this operation, suitable entry is exported in sysfs which indicate the number of maximum bytes allowed in one write zeroes operation by the device.

PCI: Create revision file in sysfs
Currently the revision isn't available via sysfs/libudev thus if one wants to know the value one needs to read through the config file, which can be quite time-consuming because it wakes/powers up the device. There are at least two userspace components which could make use the new file: libpciaccess and libdrm. The former wakes up _every_ PCI device, which can be observed via glxinfo when using Mesa 10.0+ drivers. The latter, in association with Mesa 13.0, can lead to 2-3 second delays while starting firefox, thunderbird or chromium.

PM / sleep: System sleep state selection interface rework
There are systems in which the platform doesn't support any special
sleep states, so suspend-to-idle (PM_SUSPEND_FREEZE) is the only
available system sleep state. However, some user space frameworks
only use the "mem" and (sometimes) "standby" sleep state labels, so
the users of those systems need to modify user space in order to be
able to use system suspend at all and that may be a pain in practice.

phy: rcar-gen3-usb2: add sysfs for usb role swap
This patch adds sysfs "role" for usb role swap. This parameter can be read and write. If you use this file as the following, you can swap the usb role. For example: 1) Connect a usb cable using 2 Salvator-x boards 2) On A-Device (ID pin is low), you input the following command: # echo peripheral > /sys/devices/platform/soc/ee080200.usb-phy/role 3) On B-Device (ID pin is high), 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. (even if you disconnect the usb cable, since id state may be the same, the A-Device keeps to act as peripheral.) # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Reviewed-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> |

Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex
use we have had with an analog front end made from discrete components.
Brian Masney's work on moving the tsl2583 driver out of staging also
feature extensively!
New Drivers
* DAC based on a digital potentiometer
- New driver for the use of a dpot as a DAC. Includes bindings and Axentia
entry in vendor prefixes.
* Envelope detector baed on DAC and a comparator including device tree
bindings.
Staging Graduation
* tsl2583.
Core new features
- Core provision for _available attributes. This one had been stalled for
a long time until Peter picked it up and ran with it!
- In kernel interface helpers to retrieve available info from channels.
Driver new features
* mcp4531
- Add range of available raw values (used for the dpot dac driver).
Driver cleanups and fixes for issues introduced
* ad7766
- Testing the wrong variable following devm_regulator_bulk_get introduced
with the driver earlier in this cycle.
* ad9832
- Fix a wrong ordering in the probe introduced in the previous set of
patches. A use before allocation bug.
* cros_ec_sensors
- Testing for an error in a u8 will never work.
* mpu3050
- Remove duplicate initializer for the module owner.
- Add missing i2c dependency.
- Inform the i2c mux core how it is used - step one in implifying device
tree bindings.
* st-sensors
- Get rid of large number of uninformative defines in favour of putting the
constants where they are relevant. It is clear what they are from where
they are used.
* tsl2583
- Fix unused function warning when CONFIG_PM disabled and remove the
ifdefs in favour of __maybe_unused.
- Refactor taos_chip_on to only read relevant registers.
- Make sure calibscale and integration time are being set.
- Verify chip is in ready to be used before calibration.
- Remove some repeated checks for chip status (it's protected by a mutex
so can't change until it's released)
- Change current state storage from a tristate enum to a boolean seeing as
only two values are actually used now.
- Drop a redundant write to the control regiser in taos_probe (it's a noop)
- Drop the FSF mailing address.
- Clean up logging to not use hard coded function names (use __func__
instead).
- Cleanup up variable and function name prefixes.
- Alignment of #define fixes.
- Fix comparison between signed and unsigned integer warnings.
- Add some newlines in favour of readability.
- Combine the two sysfs ABI docs that somehow ended up in different places.
- Fix multiline comment syntax.
- Move a code block to inside an else statement as it makes more sense there.
- Change tsl2583_als_calibrate to return 0 rather than a value nothing
reads.
- Drop some pointless brackets
- Don't assume 32bit unsigned int.
- Change to a per device instance lux table.
- Add missing tsl2583 to the list of supported devices in the intro comments.
- Improve commment on clearing of interrupts.
- Drop some uninformative comments.
- Drop a memset call that doesn't do anything useful any more.
- Don't initialize some return variables that are always set.
- Add Brian Masney as a module author after all these changes.

iio: dpot-dac: DAC driver based on a digital potentiometer
It is assumed that the dpot is used as a voltage divider between the
current dpot wiper setting and the maximum resistance of the dpot. The
divided voltage is provided by a vref regulator.

driver core: Add deferred_probe attribute to devices in sysfs
It is sometimes useful to know that a device is on the deferred probe list rather than, say, not having a driver available. Expose this information to user-space. Signed-off-by: Ben Hutchings <ben.hutchings@codethink.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Second round of new device support, cleanups and fixes for IIO in the 4.10 cycle
This includes two branch merges for elements that may also go via MFD.
New device support
* cros_ec
- new driver to support these Chrome OS contiguous sensors which are behind
the Chrome OS embedded controller. Requires a few minor MFD and chrome
platform changes. One follow up fix deals with some dependency issues in
Kconfig.
* mpu-3050
- new driver and device tree bindings for this venerable device.
* st_accel
- support for the lng2dm an
Driver features
* ad7192
- Add DVdd regulator handling
* ad9832
- Add DVDD regulator handling
* at91
- Suspend and resume support
* si7020
- Device tree bindings
* ti-am335x
- DMA support - uses dma to accelerate short bursts of read back rather
than full blown DMA buffer support. Greatly improved performance.
Includes an MFD addition to give access to the address needed for DMA.
* tsl2583
- Device tree bindings
Cleanups and minor fixes
* ad7192
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
- Rename reg variable to reflect which regulator it is
* ad5933
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* ad7746
- Fix a missing return value (fallout from previous patch set)
* ad7780
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* ad9832
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
- Rename reg regulator to reflect which one it is
* ad9834
- Fix regulator naming to match datasheet
- Handle regulator errors correctly (so as to not break deferred probing)
* hts221
- Remove a duplicated include
* maxim thermocouple
- Handle a wrong storage side in read function. Prevent any problems that
might be introduced by additions to this driver in future.
* tsl2583 - big set from Brian Masney to drive this towards a staging
graduation.
- Convert to iio_chan_spec and read_raw / write_raw (in a couple of steps)
- Improved error handling in various functions
- Drop redundant power_state custom sysfs attribute.
- Use IIO_*_ATTR* macros for remaining attributes.
- Return an error code to userspace on invalid parameters being writen to
sysfs files.
- Add locking to various attribute accesses to remove possible races.
- Add defines for various magic numbers.
- Use smbus_read_byte_data instead of a write_byte followed by read_byte.
- Query only relevant registers in probe.
- Tidy up ordering of code comments.
- Remove a pointless power off sequence in taos_chip_on.
- Don't bother shutting down the chip when updating the lux table.
The table is held entirely in the driver and doesn't effect the chip at all.
- Drop a redundant i2c call in taos_als_calibrate where the same register
is read twice in a row.
