can: janz-ican3: add support for CAL/CANopen firmware
In our department we are using some older Janz ICAN3-modules in our dekstop pcs. There we have slightly different carrier boards than the janz-cmodio supported in the kernel sources, called CAN-PCI2 with two submodules. But the pci configuration regions are identical. So extending the supported pci devices to the corresponding device ids is sufficient to get the drivers working. * The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart after reset. I've increased the timeout to 500ms. * The janz_ican3 module uses the raw can services of the Janz-firmware, this means firmware must be ICANOS/2. Our ICAN3-modules are equipped with CAL/CANopen-firmware, so I must use the appropriate commands for the layer management services. Te driver detects the firmware after module reset and selects the commands matching the firmware. This affects the bus on/off-command (ican3_set_bus_state) and the configuration of the bittiming (ican3_set_bittiming). For better diagnostics the detected firmware string is presented as sysfs attribute (fwinfo).

bridge: change BR_GROUPFWD_RESTRICTED to allow forwarding of LLDP frames
BR_GROUPFWD_RESTRICTED bitmask restricts users from setting values to /sys/class/net/brX/bridge/group_fwd_mask that allow forwarding of some IEEE 802.1D Table 7-10 Reserved addresses: (MAC Control) 802.3 01-80-C2-00-00-01 (Link Aggregation) 802.3 01-80-C2-00-00-02 802.1AB LLDP 01-80-C2-00-00-0E Change BR_GROUPFWD_RESTRICTED to allow to forward LLDP frames and document group_fwd_mask. e.g. echo 16384 > /sys/class/net/brX/bridge/group_fwd_mask allows to forward LLDP frames. This may be needed for bridge setups used for network troubleshooting or any other scenario where forwarding of LLDP frames is desired (e.g. bridge connecting a virtual machine to real switch transmitting LLDP frames that virtual machine needs to receive). Tested on a simple bridge setup with two interfaces and host transmitting LLDP frames on one side of this bridge (used lldpd). Setting group_fwd_mask as described above lets LLDP frames traverse bridge. Signed-off-by: Bernhard Thaler <bernhard.thaler@wvnet.at> Signed-off-by: David S. Miller <davem@davemloft.net> |

efi: Add esrt support
Add sysfs files for the EFI System Resource Table (ESRT) under /sys/firmware/efi/esrt and for each EFI System Resource Entry under entries/ as a subdir. The EFI System Resource Table (ESRT) provides a read-only catalog of system components for which the system accepts firmware upgrades via UEFI's "Capsule Update" feature. This module allows userland utilities to evaluate what firmware updates can be applied to this system, and potentially arrange for those updates to occur. The ESRT is described as part of the UEFI specification, in version 2.5 which should be available from http://uefi.org/specifications in early 2015. If you're a member of the UEFI Forum, information about its addition to the standard is available as UEFI Mantis 1090. For some hardware platforms, additional restrictions may be found at http://msdn.microsoft.com/en-us/library/windows/hardware/jj128256.aspx , and additional documentation may be found at http://download.microsoft.com/download/5/F/5/5F5D16CD-2530-4289-8019-94C6A20BED3C/windows-uefi-firmware-update-platform.docx .

Common MTD:
* Add Kconfig option for keeping both the 'master' and 'partition' MTDs
registered as devices. This would really make a better default if we could
do it over, as it allows a lot more flexibility in (1) determining the flash
topology of the system from user-space and (2) adding temporary partitions
at runtime (ioctl(BLKPG)). Unfortunately, this would possibly cause
user-space breakage, as it will cause renumbering of the /dev/mtdX devices.
We'll see if we can change this in the future, as there have already been a
few people looking for this feature, and I know others have just been
working around our current limitations instead of fixing them this way.
* Along with the previous change, add some additional information to sysfs, so
user-space can read the offset of each partition within its master device
SPI NOR:
* add new device tree compatible binding to represent the mostly-compatible
class of SPI NOR flash which can be detected by their extended JEDEC ID
bytes, cutting down the duplication of our ID tables
* misc. new IDs
Various other miscellaneous fixes and changes

- Most extensive changes this cycle are the DM core improvements to add
full blk-mq support to request-based DM.
- disabled by default but user can opt-in with CONFIG_DM_MQ_DEFAULT
- depends on some blk-mq changes from Jens' for-4.1/core branch so
that explains why this pull is built on linux-block.git
- Update DM to use name_to_dev_t() rather than open-coding a less
capable device parser.
- includes a couple small improvements to name_to_dev_t() that offer
stricter constraints that DM's code provided.
- Improvements to the dm-cache "mq" cache replacement policy.
- A DM crypt crypt_ctr() error path fix and an async crypto deadlock fix.
- A small efficiency improvement for DM crypt decryption by leveraging
immutable biovecs.
- Add error handling modes for corrupted blocks to DM verity.
- A new "log-writes" DM target from Josef Bacik that is meant for
file system developers to test file system integrity at particular
points in the life of a file system.
- A few DM log userspace cleanups and fixes.
- A few Documentation fixes (for thin, cache, crypt and switch).

zram: deprecate zram attrs sysfs nodes
Add Documentation/ABI/obsolete/sysfs-block-zram file and list obsolete and deprecated attributes there. The patch also adds additional information to zram documentation and describes the basic strategy: - the existing RW nodes will be downgraded to WO nodes (in 4.11) - deprecated RO sysfs nodes will eventually be removed (in 4.11) Users will be additionally notified about deprecated attr usage by pr_warn_once() (added to every deprecated attr _show()), as suggested by Minchan Kim. User space is advised to use zram<id>/stat, zram<id>/io_stat and zram<id>/mm_stat files.

zram: export new 'io_stat' sysfs attrs
Per-device `zram<id>/io_stat' file provides accumulated I/O statistics of
particular zram device in a format similar to block layer statistics. The
file consists of a single line and represents the following stats
(separated by whitespace):
failed_reads
failed_writes
invalid_io
notify_free

zram: remove `num_migrated' device attr
This patch introduces rework to zram stats. We have per-stat sysfs nodes,
and it makes things a bit hard to use in user space: it doesn't give an
immediate stats 'snapshot', it requires user space to use more syscalls -
open, read, close for every stat file, with appropriate error checks on
every step, etc.
First, zram now accounts block layer statistics, available in
/sys/block/zram<id>/stat and /proc/diskstats files. So some new stats are
available (see Documentation/block/stat.txt), besides, zram's activities
now can be monitored by sysstat's iostat or similar tools.
Example:
cat /sys/block/zram0/stat
248 0 1984 0 251029 0 2008232 5120 0 5116 5116
Second, group currently exported on per-stat basis nodes into two
categories (files):
-- zram<id>/io_stat
accumulates device's IO stats, that are not accounted by block layer,
and contains:
failed_reads
failed_writes
invalid_io
notify_free
Example:
cat /sys/block/zram0/io_stat
0 0 0 652572
-- zram<id>/mm_stat
accumulates zram mm stats and contains:
orig_data_size
compr_data_size
mem_used_total
mem_limit
mem_used_max
zero_pages
num_migrated
Example:
cat /sys/block/zram0/mm_stat
434634752 270288572 279158784 0 579895296 15060 0
per-stat sysfs nodes are now considered to be deprecated and we plan to
remove them (and clean up some of the existing stat code) in two years (as
of now, there is no warning printed to syslog about deprecated stats being
used). User space is advised to use the above mentioned 3 files.
This patch (of 7):
Remove sysfs `num_migrated' attribute. We are moving away from per-stat
device attrs towards 3 stat files that will accumulate io and mm stats in
a format similar to block layer statistics in /sys/block/<dev>/stat. That
will be easier to use in user space, and reduce the number of syscalls
needed to read zram device statistics.
`num_migrated' will return back in zram<id>/mm_stat file.

dm: add 'use_blk_mq' module param and expose in per-device ro sysfs attr
Request-based DM's blk-mq support defaults to off; but a user can easily change the default using the dm_mod.use_blk_mq module/boot option. Also, you can check what mode a given request-based DM device is using with: cat /sys/block/dm-X/dm/use_blk_mq This change enabled further cleanup and reduced work (e.g. the md->io_pool and md->rq_pool isn't created if using blk-mq).

dm: impose configurable deadline for dm_request_fn's merge heuristic
Otherwise, for sequential workloads, the dm_request_fn can allow excessive request merging at the expense of increased service time. Add a per-device sysfs attribute to allow the user to control how long a request, that is a reasonable merge candidate, can be queued on the request queue. The resolution of this request dispatch deadline is in microseconds (ranging from 1 to 100000 usecs), to set a 20us deadline: echo 20 > /sys/block/dm-7/dm/rq_based_seq_io_merge_deadline The dm_request_fn's merge heuristic and associated extra accounting is disabled by default (rq_based_seq_io_merge_deadline is 0). This sysfs attribute is not applicable to bio-based DM devices so it will only ever report 0 for them. By allowing a request to remain on the queue it will block others requests on the queue. But introducing a short dequeue delay has proven very effective at enabling certain sequential IO workloads on really fast, yet IOPS constrained, devices to build up slightly larger IOs -- yielding 90+% throughput improvements. Having precise control over the time taken to wait for larger requests to build affords control beyond that of waiting for certain IO sizes to accumulate (which would require a deadline anyway). This knob will only ever make sense with sequential IO workloads and the particular value used is storage configuration specific. Given the expected niche use-case for when this knob is useful it has been deemed acceptable to expose this relatively crude method for crafting optimal IO on specific storage -- especially given the solution is simple yet effective. In the context of DM multipath, it is advisable to tune this sysfs attribute to a value that offers the best performance for the common case (e.g. if 4 paths are expected active, tune for that; if paths fail then performance may be slightly reduced). Alternatives were explored to have request-based DM autotune this value (e.g. if/when paths fail) but they were quickly deemed too fragile and complex to warrant further design and development time. If this problem proves more common as faster storage emerges we'll have to look at elevating a generic solution into the block core.

iio: add support for hardware fifo
Some devices have hardware buffers that can store a number of samples for later consumption. Hardware usually provides interrupts to notify the processor when the FIFO is full or when it has reached a certain watermark level. This helps with reducing the number of interrupts to the host processor and thus it helps decreasing the power consumption. This patch enables usage of hardware FIFOs for IIO devices in conjunction with software device buffers. When the hardware FIFO is enabled the samples are stored in the hardware FIFO. The samples are later flushed to the device software buffer when the number of entries in the hardware FIFO reaches the hardware watermark or when a flush operation is triggered by the user when doing a non-blocking read on an empty software device buffer. In order to implement hardware FIFO support the device drivers must implement the following new operations: setting and getting the hardware FIFO watermark level, flushing the hardware FIFO to the software device buffer. The device must also expose information about the hardware FIFO such it's minimum and maximum watermark and if necessary a list of supported watermark values. Finally, the device driver must activate the hardware FIFO when the device buffer is enabled, if the current device settings allows it. The software device buffer watermark is passed by the IIO core to the device driver as a hint for the hardware FIFO watermark. The device driver can adjust this value to allow for hardware limitations (such as capping it to the maximum hardware watermark or adjust it to a value that is supported by the hardware). It can also disable the hardware watermark (and implicitly the hardware FIFO) it this value is below the minimum hardware watermark. Since a driver may support hardware FIFO only when not in triggered buffer mode (due to different semantics of hardware FIFO sampling and triggered sampling) this patch changes the IIO core code to allow falling back to non-triggered buffered mode if no trigger is enabled.

drivers/core/of: Add symlink to device-tree from devices with an OF node
So I've been annoyed lately with having a bunch of devices such as i2c eeproms (for use by VPDs, server world !) and other bits and pieces that I want to be able to identify from userspace, and possibly provide additional data about from FW. Basically, it boils down to correlating the sysfs device with the OF tree device node, so that user space can use device-tree info such as additional "location" or "label" (or whatever else we can come up with) propreties to identify a given device, or get some attributes of use about it, etc... Now, so far, we've done that in some subsystem in a fairly ad-hoc basis using "devspec" properties. For example, PCI creates them if it can correlate the probed device with a DT node. Some powerpc specific busses do that too. However, i2c doesn't and it would be nice to have something more generic since technically any device can have a corresponding device tree node. This patch adds an "of_node" symlink to devices that have a non-NULL dev->of_node pointer, the patch is pretty trivial and seems to work just fine for me.

* MS5611 pressure and temperature sensor.
New functionality
* mup6050 - create mux clients for devices described via ACPI. The reasoning
and approach taken in this patch are complex. Basically there is no
otherway of finding out what is there than by some esoteric look ups in
the ACPI data.
* cm3232 - PM support
* itg3200 - suspend/resume support
* mcp320x - add more ADCs to the kconfig to reflect what the driver supports
(this patch and the bindings got left behind when the support was added
a while back).
Docs / utils
* ti-adc128s052 - DT bindings.
* mcp3422 - DT bindings.
* mcp320x - DT bindings
* ABI docs for event threshold scale attributes, in_magn_offset, proximity
scan_element and thresh falling/rising values for accelerometers. All
elements long in use that have slipped by being explicitly documented.
* Tidy up the tools previously in drivers/staging/iio/Documentation and move
them out to /tools/iio. Yet another move that should have happened long ago.
This time Roberta Dobrescu did the leg work. Thanks!
Core Cleanups
* Export userspace IIO headers. We should have done the appropriate header
splitting a long time ago. Thanks to Daniel for sorting this out.
* Refactor the registring of attributes for buffers to move all non-custom
ones to a vector allowing easier additions to the current set in the future.
Driver Cleanups
* gpiod related cleanups. Make use of the additional parameter to specify
initial direciton to avoid extra code.
* bmc150 - Various refactorings to reduce code repitition and prepare for
hardware buffer support. Some of these cleanups are good even
without the new functionality.
* kmx61 - direct use of index to an array avoiding a structure element which
was always the index to an element in an array of that structure.
* vf610 - avoid incorrect type for return from wait_for_completion_timeout.
* gp2ap020a00f - use put_unaligned_le32 for slight code simplification.
* ade7754 - improve error handling including suppressing some build warnings.
* ade7759 - improve error handling including suppressing some build warnings.
* hmc5843 - Long line and indentation fixes. Also some constifying of various
constant data.

net: add support for phys_port_name
Similar to port id allow netdevices to specify port names and export
the name via sysfs. Drivers can implement the netdevice operation to
assist udev in having sane default names for the devices using the
rule:
$ cat /etc/udev/rules.d/80-net-setup-link.rules
SUBSYSTEM=="net", ACTION=="add", ATTR{phys_port_name}!="",
NAME="$attr{phys_port_name}"
Use of phys_name versus phys_id was suggested-by Jiri Pirko.

net: Add max rate tx queue attribute
This adds a tx_maxrate attribute to the tx queue sysfs entry allowing for max-rate limiting. Along with DCB-ETS and BQL this provides another knob to tune queue performance. The limit units are Mbps. By default it is disabled. To disable the rate limitation after it has been set for a queue, it should be set to zero.

HID: expose country code in sysfs
This commit exposes in sysfs the HID country code that is stored in the country member of hid_device structure. It identifies the country code of localized hardware. For example some keyboards use it to exhibit the language of the key layout. It helps the upper layer to identify the localized hardware and setup the correct language to use. For USB HID devices the country code comes for the HID descriptor and for Bluetooth HID devices it is the HIDCountryCode attribute from the SDP database.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull live patching infrastructure from Jiri Kosina:
"Let me provide a bit of history first, before describing what is in
this pile.
Originally, there was kSplice as a standalone project that implemented
stop_machine()-based patching for the linux kernel. This project got
later acquired, and the current owner is providing live patching as a
proprietary service, without any intentions to have their
implementation merged.
Then, due to rising user/customer demand, both Red Hat and SUSE
started working on their own implementation (not knowing about each
other), and announced first versions roughly at the same time [1] [2].
The principle difference between the two solutions is how they are
making sure that the patching is performed in a consistent way when it
comes to different execution threads with respect to the semantic
nature of the change that is being introduced.
In a nutshell, kPatch is issuing stop_machine(), then looking at
stacks of all existing processess, and if it decides that the system
is in a state that can be patched safely, it proceeds insterting code
redirection machinery to the patched functions.
On the other hand, kGraft provides a per-thread consistency during one
single pass of a process through the kernel and performs a lazy
contignuous migration of threads from "unpatched" universe to the
"patched" one at safe checkpoints.
If interested in a more detailed discussion about the consistency
models and its possible combinations, please see the thread that
evolved around [3].
It pretty quickly became obvious to the interested parties that it's
absolutely impractical in this case to have several isolated solutions
for one task to co-exist in the kernel. During a dedicated Live
Kernel Patching track at LPC in Dusseldorf, all the interested parties
sat together and came up with a joint aproach that would work for both
distro vendors. Steven Rostedt took notes [4] from this meeting.
And the foundation for that aproach is what's present in this pull
request.
It provides a basic infrastructure for function "live patching" (i.e.
code redirection), including API for kernel modules containing the
actual patches, and API/ABI for userspace to be able to operate on the
patches (look up what patches are applied, enable/disable them, etc).
It's relatively simple and minimalistic, as it's making use of
existing kernel infrastructure (namely ftrace) as much as possible.
It's also self-contained, in a sense that it doesn't hook itself in
any other kernel subsystem (it doesn't even touch any other code).
It's now implemented for x86 only as a reference architecture, but
support for powerpc, s390 and arm is already in the works (adding
arch-specific support basically boils down to teaching ftrace about
regs-saving).
Once this common infrastructure gets merged, both Red Hat and SUSE
have agreed to immediately start porting their current solutions on
top of this, abandoning their out-of-tree code. The plan basically is
that each patch will be marked by flag(s) that would indicate which
consistency model it is willing to use (again, the details have been
sketched out already in the thread at [3]).
Before this happens, the current codebase can be used to patch a large
group of secruity/stability problems the patches for which are not too
complex (in a sense that they don't introduce non-trivial change of
function's return value semantics, they don't change layout of data
structures, etc) -- this corresponds to LEAVE_FUNCTION &&
SWITCH_FUNCTION semantics described at [3].
This tree has been in linux-next since December.

[ The core code is introduced by the three commits authored by Seth
Jennings, which got a lot of changes incorporated during numerous
respins and reviews of the initial implementation. All the followup
commits have materialized only after public tree has been created,
so they were not folded into initial three commits so that the

samsung-laptop: enable better lid handling
Some Samsung laptops with SABI3 delay the sleep for 10 seconds after
the lid is closed and do not wake up from sleep after the lid is opened.
A SABI command is needed to enable the better behavior.
Command = 0x6e, d0 = 0x81 enables this behavior. Returns d0 = 0x01.
Command = 0x6e, d0 = 0x80 disables this behavior. Returns d0 = 0x00.
Command = 0x6d and any d0 queries the state. This returns:
d0 = 0x00000*01, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is enabled.
d0 = 0x00000*00, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is disabled.
Where * is 0 - laptop has never slept or hibernated after switch on,
1 - laptop has hibernated just before,
2 - laptop has slept just before.
Patch addresses bug https://bugzilla.kernel.org/show_bug.cgi?id=75901 .
It adds a sysfs attribute lid_handling with a description and also an
addition to the quirks structure to enable the mode by default.
A user with another laptop in the bug report says that "power button has
to be pressed twice to wake the machine" when he or she enabled the mode
manually using the SABI command. Therefore, it is enabled by default
only for the single laptop that I have tested.

cxl: Export optional AFU configuration record in sysfs
An AFU may optionally contain one or more PCIe like configuration records, which can be used to identify the AFU. This patch adds support for exposing the raw config space and the vendor, device and class code under sysfs. These will appear in a subdirectory of the AFU device corresponding with the configuration record number, e.g. cat /sys/class/cxl/afu0.0/cr0/vendor 0x1014 cat /sys/class/cxl/afu0.0/cr0/device 0x4350 cat /sys/class/cxl/afu0.0/cr0/class 0x120000 hexdump -C /sys/class/cxl/afu0.0/cr0/config 00000000 14 10 50 43 00 00 00 00 06 00 00 12 00 00 00 00 |..PC............| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000100 These files behave in much the same way as the equivalent files for PCI devices, with one exception being that the config file is currently read-only and restricted to the root user. It is not necessarily required to be this strict, but we currently do not have a compelling use-case to make it writable and/or world-readable, so I erred on the side of being restrictive.

iio: core: Introduce IIO_CHAN_INFO_DEBOUNCE_COUNT and _TIME
The pedometer needs to filter out false steps that might be generated by tapping the foot, sitting, etc. To do that it computes the number of steps that occur in a given time and decides the user is moving only if this value is over a threshold. E.g.: the user starts moving only if he takes 4 steps in 3 seconds. This filter is applied only when the user starts moving. A device that has such pedometer functionality is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf. To export this feature, this patch introduces IIO_CHAN_INFO_DEBOUNCE_COUNT and IIO_CHAN_INFO_DEBOUNCE_TIME. For the pedometer, in_steps_debounce_count will specify the number of steps that need to occur in in_steps_debounce_time seconds so that the pedometer decides the user is moving.

cxl: Add ability to reset the card
Adds reset to sysfs which will PERST the card. If load_image_on_perst is set to "user" or "factory", the PERST will cause that image to be loaded. load_image_on_perst is set to "user" for production. "none" could be used for debugging. The PSL trace arrays are preserved which then can be read through debugfs. PERST also triggers CAPP recovery. An HMI comes in, which is handled by EEH. EEH unbinds the driver, calls into Sapphire to reinitialize the PHB, then rebinds the driver.

cxl: Add image control to sysfs
load_image_on_perst identifies whether a PERST will cause the image to be flashed to the card. And if so, which image. Valid entries are: "none", "user" and "factory". A value of "none" means PERST will not cause the image to be flashed. A power cycle to the pcie slot is required to load the image. "user" loads the user provided image and "factory" loads the factory image upon PERST. sysfs updates the cxl struct in the driver then calls cxl_update_image_control to write the vals in the VSEC.

perf Documentation: Add event parameters
Event parameters are a basic way for partial events to be specified in sysfs with per-event names given to the fields that need to be filled in when using a particular event. It is intended for supporting cases where the single 'cpu' parameter is insufficient. For example, POWER 8 has events for physical sockets/cores/cpus that are accessible from with virtual machines. To keep using the single 'cpu' parameter we'd need to perform a mapping between Linux's cpus and the physical machine's cpus (in this case Linux is running under a hypervisor). This isn't possible because bindings between our cpus and physical cpus may not be fixed, and we probably won't have a "cpu" on each physical cpu.

First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2
Updated pull request with Daniel's fix on top for the power management
Kconfig changes that had snuck in since last update of the IIO tree
worked it's way through from mainline.
Original pull message
New device support
* jsa1212 proxmity / ambient light sensor
* SM08500 supported added to the kxcjk-1013 accelerometer driver
* KMX61 Accelerometer/Magnetometer. This took a somewhat rocky path
being first merged, then reverted for a rewrite after a discussion of
how to support additional functionality and finally being merged prior
to some last reviews coming in, with resultant follow up patches.
* Freescale mma9551l driver (minor follow up warning supression patch).
* Semtech SX9500 proximity device driver.
* ak8975 gains support for ak09911 and ak09912 and drop the standalone driver
for the ak09911.
New functionality
* Dummy driver gains some virtual registers making it more flexible.
* IIO_ACTIVITY channel types, with modifiers running, walking etc. This is
to support on chip motion clasifiers. As such it is in the form of a
confidence percentage. The only devices so far only do binary decisions
but this gives us room when other devices give more nuanced clasification.
* IIO_EV_DIR_NONE type for events where there is no obvious direction.
First case is step detection.
* IIO_STEPS channel type for pedometers.
* ENABLE mask element used to control turning on counting types such as
the pedometer that need a 'start point'.
* INSTANCE event type to support things that happen once.
* info element for height calibration (used in various motion estimation
algorithms). Note heigh tof use
* dummy driver demonstration of the use of all the new bits above.
* event monitor support for the new events.
* inv_mpu6050 gains an i2c mux to allow bypassing the device to access
additional devices connected on the other side of it. Note that in
Windows these are handled by firmware on the device and not exposed
directly.
* inv_mpu6050 gains ACPI enumeration.
* inkern interface gains iio_write_channel_raw to allow in kernel users
of DAC functionality via a simple wrapper.
* Document input current readings in the ABI docs.
* Add an error message when we get an out of range error in device tree
processing for the in kernel interfaces. Basically a device tree debugging
aid.
* Add a sanity check that a scan index for a channel is unique during
registration. There to help catch bugs as this should never happen
in a bug free driver.
Cleanups and fixlets
A rework of buffer registration from Lars - a precursor to some other
upcoming new stuff (a few patches from others rolled in here as well).
* Ensure all drivers register the same channels for the device and buffer.
* Move buffer registration into the core rather than using the old
two step approach. Now we have simple ways of using a unified set channels
for both without requiring channels be exposed by both interface, this
removes a fair bit of boilerplate.
* Stop sca3000 and ad5933 (both in staging) enabling buffer channels by
default. It has long be convention in IIO to startup with no channels
enabled and leave it up to userspace to say what goes in the buffer.
Getting rid of these allows us to drop export of iio_scan_mask_set.
* Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used
for a while.
* Allocate standard buffer attributes in the core rather than in every
driver with a buffer.
* Make the length attribute read only when a driver is not able to set
the length.
* Drop the get_length callback for buffers as it is already available in
struct iio_buffer.
* Drop an unused arguement form iio_kfifo_allocate and add devm allocator
for it.
* some kconfig entries gain anotation with the resulting module name.
* Fix a resulting compile issue in dummy driver due to a stub taking
wrong parameters as a result of the above rework.
* Fix an off by 2 error in copying the core assigned buffer attributes.
Other cleanups,
* Trivial space before comma fixups.
* ak8975 fixlets - none critical. Rework to allow more device support.
* Drop unnecessary sizeof(u8) calls.
* bmp280 - refactor the compensation code to reduce copy operations and
code length. A second patch futher optimized this and performed some
other minor cleanups.
* kxcjk-1013 - various power control cleanups to avoid unnecessary enable
/ disable of device. Make sure it is only controlled at all if CONFIG_PM
is enabled. Also som cleanups of error paths.
* Small cleanups in adf4530 driver - pointless message and unnecessary braces.
* Clarifiy the proximity ABI docs to make it clear it should get bigger
as we move futher away.
* Drop a misleading comment form industrialio-core.c
* Trivial white space cleanups.
* sca3000 looses an unused debug function.
* Fix char unsigned ordering in ad8366
* Increase the sleep time in ad9523 to make it predictable (value didn't
really matter so make it more than 20 msecs)
* mxs-lradc touchscreen property cleanups in device tree are fixed to ensure
the meet all the 'interesting' documentation.
* A couple of cleanups for the staging ad5933 driver to avoid unnecessary
conversion to a processed temperature vlaue in kernel and remove
platform data form the state structure as not needed after probe.
* Fix a wrong scale factor in the docs.
Misc
* Add IIO include files to the maintainers entry.

tpm: device class for tpm
Added own device class for TPM. Uses MISC_MAJOR:TPM_MINOR for the first character device in order to retain backwards compatibility. Added tpm_dev_release() back attached to the character device. I've been running this code now for a while on my laptop (Lenovo T430S) TrouSerS works perfectly without modifications. I don't believe it breaks anything significantly. The sysfs attributes that have been placed under the wrong place and are against sysfs-rules.txt should be probably left to stagnate under platform device directory and start defining new sysfs attributes to the char device directory. Guidelines for future TPM sysfs attributes should be probably along the lines of - Single flat set of mandatory sysfs attributes. For example, current PPI interface is way way too rich when you only want to use it to clear and activate the TPM. - Define sysfs attribute if and only if there's no way to get the value from ring-3. No attributes for TPM properties. It's just unnecessary maintenance hurdle that we don't want.

livepatch: kernel: add support for live patching
This commit introduces code for the live patching core. It implements an ftrace-based mechanism and kernel interface for doing live patching of kernel and kernel module functions. It represents the greatest common functionality set between kpatch and kgraft and can accept patches built using either method. This first version does not implement any consistency mechanism that ensures that old and new code do not run together. In practice, ~90% of CVEs are safe to apply in this way, since they simply add a conditional check. However, any function change that can not execute safely with the old version of the function can _not_ be safely applied in this version.

Staging patches for 3.19-rc1
Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

ACPI and power management updates for 3.19-rc1
This time we have some more new material than we used to have during
the last couple of development cycles.
The most important part of it to me is the introduction of a unified
interface for accessing device properties provided by platform
firmware. It works with Device Trees and ACPI in a uniform way and
drivers using it need not worry about where the properties come
from as long as the platform firmware (either DT or ACPI) makes
them available. It covers both devices and "bare" device node
objects without struct device representation as that turns out to
be necessary in some cases. This has been in the works for quite
a few months (and development cycles) and has been approved by
all of the relevant maintainers.
On top of that, some drivers are switched over to the new interface
(at25, leds-gpio, gpio_keys_polled) and some additional changes are
made to the core GPIO subsystem to allow device drivers to manipulate
GPIOs in the "canonical" way on platforms that provide GPIO information
in their ACPI tables, but don't assign names to GPIO lines (in which
case the driver needs to do that on the basis of what it knows about
the device in question). That also has been approved by the GPIO
core maintainers and the rfkill driver is now going to use it.
Second is support for hardware P-states in the intel_pstate driver.
It uses CPUID to detect whether or not the feature is supported by
the processor in which case it will be enabled by default. However,
it can be disabled entirely from the kernel command line if necessary.
Next is support for a platform firmware interface based on ACPI
operation regions used by the PMIC (Power Management Integrated
Circuit) chips on the Intel Baytrail-T and Baytrail-T-CR platforms.
That interface is used for manipulating power resources and for
thermal management: sensor temperature reporting, trip point setting
and so on.
Also the ACPI core is now going to support the _DEP configuration
information in a limited way. Basically, _DEP it supposed to reflect
off-the-hierarchy dependencies between devices which may be very
indirect, like when AML for one device accesses locations in an
operation region handled by another device's driver (usually, the
device depended on this way is a serial bus or GPIO controller).
The support added this time is sufficient to make the ACPI battery
driver work on Asus T100A, but it is general enough to be able to
cover some other use cases in the future.
Finally, we have a new cpufreq driver for the Loongson1B processor.
In addition to the above, there are fixes and cleanups all over the
place as usual and a traditional ACPICA update to a recent upstream
release.
As far as the fixes go, the ACPI LPSS (Low-power Subsystem) driver
for Intel platforms should be able to handle power management of
the DMA engine correctly, the cpufreq-dt driver should interact
with the thermal subsystem in a better way and the ACPI backlight
driver should handle some more corner cases, among other things.
On top of the ACPICA update there are fixes for race conditions
in the ACPICA's interrupt handling code which might lead to some
random and strange looking failures on some systems.
In the cleanups department the most visible part is the series
of commits targeted at getting rid of the CONFIG_PM_RUNTIME
configuration option. That was triggered by a discussion
regarding the generic power domains code during which we realized
that trying to support certain combinations of PM config options
was painful and not really worth it, because nobody would use them
in production anyway. For this reason, we decided to make
CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and that lead to the
conclusion that the latter became redundant and CONFIG_PM could
be used instead of it. The material here makes that replacement
in a major part of the tree, but there will be at least one more
batch of that in the second part of the merge window.
Specifics:
- Support for retrieving device properties information from ACPI
_DSD device configuration objects and a unified device properties
interface for device drivers (and subsystems) on top of that.
As stated above, this works with Device Trees and ACPI and allows
device drivers to be written in a platform firmware (DT or ACPI)
agnostic way. The at25, leds-gpio and gpio_keys_polled drivers
are now going to use this new interface and the GPIO subsystem
is additionally modified to allow device drivers to assign names
to GPIO resources returned by ACPI _CRS objects (in case _DSD is
not present or does not provide the expected data). The changes
in this set are mostly from Mika Westerberg, Rafael J Wysocki,
Aaron Lu, and Darren Hart with some fixes from others (Fabio Estevam,
Geert Uytterhoeven).
- Support for Hardware Managed Performance States (HWP) as described
in Volume 3, section 14.4, of the Intel SDM in the intel_pstate
driver. CPUID is used to detect whether or not the feature is
supported by the processor. If supported, it will be enabled
automatically unless the intel_pstate=no_hwp switch is present in
the kernel command line. From Dirk Brandewie.
- New Intel Broadwell-H ID for intel_pstate (Dirk Brandewie).
- Support for firmware interface based on ACPI operation regions
used by the PMIC chips on the Intel Baytrail-T and Baytrail-T-CR
platforms for power resource control and thermal management
(Aaron Lu).
- Limited support for retrieving off-the-hierarchy dependencies
between devices from ACPI _DEP device configuration objects
and deferred probing support for the ACPI battery driver based
on the _DEP information to make that driver work on Asus T100A
(Lan Tianyu).
- New cpufreq driver for the Loongson1B processor (Kelvin Cheung).
- ACPICA update to upstream revision 20141107 which only affects
tools (Bob Moore).
- Fixes for race conditions in the ACPICA's interrupt handling
code and in the ACPI code related to system suspend and resume
(Lv Zheng and Rafael J Wysocki).
- ACPI core fix for an RCU-related issue in the ioremap() regions
management code that slowed down significantly after CPUs had
been allowed to enter idle states even if they'd had RCU callbakcs
queued and triggered some problems in certain proprietary graphics
driver (and elsewhere). The fix replaces synchronize_rcu() in
that code with synchronize_rcu_expedited() which makes the issue
go away. From Konstantin Khlebnikov.
- ACPI LPSS (Low-Power Subsystem) driver fix to handle power
management of the DMA engine included into the LPSS correctly.
The problem is that the DMA engine doesn't have ACPI PM support
of its own and it simply is turned off when the last LPSS device
having ACPI PM support goes into D3cold. To work around that,
the PM domain used by the ACPI LPSS driver is redesigned so at
least one device with ACPI PM support will be on as long as the
DMA engine is in use. From Andy Shevchenko.
- ACPI backlight driver fix to avoid using it on "Win8-compatible"
systems where it doesn't work and where it was used by default by
mistake (Aaron Lu).
- Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki,
Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and
Ashwin Chaugule (mostly related to the upcoming ARM64 support).
- Intel RAPL (Running Average Power Limit) power capping driver
fixes and improvements including new processor IDs (Jacob Pan).
- Generic power domains modification to power up domains after
attaching devices to them to meet the expectations of device
drivers and bus types assuming devices to be accessible at
probe time (Ulf Hansson).
- Preliminary support for controlling device clocks from the
generic power domains core code and modifications of the
ARM/shmobile platform to use that feature (Ulf Hansson).
- Assorted minor fixes and cleanups of the generic power
domains core code (Ulf Hansson, Geert Uytterhoeven).
- Assorted minor fixes and cleanups of the device clocks control
code in the PM core (Geert Uytterhoeven, Grygorii Strashko).
- Consolidation of device power management Kconfig options by making
CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter
which is now redundant (Rafael J Wysocki and Kevin Hilman). That
is the first batch of the changes needed for this purpose.
- Core device runtime power management support code cleanup related
to the execution of callbacks (Andrzej Hajda).
- cpuidle ARM support improvements (Lorenzo Pieralisi).
- cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and
a new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and
Bartlomiej Zolnierkiewicz).
- New cpufreq driver callback (->ready) to be executed when the
cpufreq core is ready to use a given policy object and cpufreq-dt
driver modification to use that callback for cooling device
registration (Viresh Kumar).
- cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu,
James Geboski, Tomeu Vizoso).
- Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate,
cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao,
Stefan Wahren, Petr Cvek).
- OPP (Operating Performance Points) framework modification to
allow OPPs to be removed too and update of a few cpufreq drivers
(cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added
during initialization) on driver removal (Viresh Kumar).
- Hibernation core fixes and cleanups (Tina Ruchandani and
Markus Elfring).
- PM Kconfig fix related to CPU power management (Pankaj Dubey).
- cpupower tool fix (Prarit Bhargava).

- Fixes for race conditions in the ACPICA's interrupt handling code
and in the ACPI code related to system suspend and resume (Lv Zheng
and Rafael J Wysocki).
- ACPI core fix for an RCU-related issue in the ioremap() regions
management code that slowed down significantly after CPUs had been
allowed to enter idle states even if they'd had RCU callbakcs
queued and triggered some problems in certain proprietary graphics
driver (and elsewhere). The fix replaces synchronize_rcu() in that
code with synchronize_rcu_expedited() which makes the issue go
away. From Konstantin Khlebnikov.
- ACPI LPSS (Low-Power Subsystem) driver fix to handle power
management of the DMA engine included into the LPSS correctly. The
problem is that the DMA engine doesn't have ACPI PM support of its
own and it simply is turned off when the last LPSS device having
ACPI PM support goes into D3cold. To work around that, the PM
domain used by the ACPI LPSS driver is redesigned so at least one
device with ACPI PM support will be on as long as the DMA engine is
in use. From Andy Shevchenko.
- ACPI backlight driver fix to avoid using it on "Win8-compatible"
systems where it doesn't work and where it was used by default by
mistake (Aaron Lu).
- Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki,
Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and Ashwin
Chaugule (mostly related to the upcoming ARM64 support).
- Intel RAPL (Running Average Power Limit) power capping driver fixes
and improvements including new processor IDs (Jacob Pan).
- Generic power domains modification to power up domains after
attaching devices to them to meet the expectations of device
drivers and bus types assuming devices to be accessible at probe
time (Ulf Hansson).
- Preliminary support for controlling device clocks from the generic
power domains core code and modifications of the ARM/shmobile
platform to use that feature (Ulf Hansson).
- Assorted minor fixes and cleanups of the generic power domains core
code (Ulf Hansson, Geert Uytterhoeven).
- Assorted minor fixes and cleanups of the device clocks control code
in the PM core (Geert Uytterhoeven, Grygorii Strashko).
- Consolidation of device power management Kconfig options by making
CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter
which is now redundant (Rafael J Wysocki and Kevin Hilman). That
is the first batch of the changes needed for this purpose.
- Core device runtime power management support code cleanup related
to the execution of callbacks (Andrzej Hajda).
- cpuidle ARM support improvements (Lorenzo Pieralisi).
- cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and a
new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and
Bartlomiej Zolnierkiewicz).
- New cpufreq driver callback (->ready) to be executed when the
cpufreq core is ready to use a given policy object and cpufreq-dt
driver modification to use that callback for cooling device
registration (Viresh Kumar).
- cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu, James
Geboski, Tomeu Vizoso).
- Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate,
cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao,
Stefan Wahren, Petr Cvek).
- OPP (Operating Performance Points) framework modification to allow
OPPs to be removed too and update of a few cpufreq drivers
(cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added
during initialization) on driver removal (Viresh Kumar).
- Hibernation core fixes and cleanups (Tina Ruchandani and Markus
Elfring).
- PM Kconfig fix related to CPU power management (Pankaj Dubey).
- cpupower tool fix (Prarit Bhargava)"

iio: core: Introduce STEPS channel, ENABLE mask and INSTANCE event
These changes are needed to support the functionality of a pedometer. A pedometer has two basic functionalities: step counter and step detector. The step counter needs to be enabled and then it will count the steps in its hardware register. Whenever the application needs to check the step count, it will read the step counter register. To support the step counter a new channel type STEPS is added. Since the pedometer needs to be enabled first so that the hardware can count and store the steps, we need a specific ENABLE channel info mask. The step detector will generate an interrupt each time a step is detected. To support this functionality we add a new event type INSTANCE. For more information on the Android requirements for step counter and step detector see: http://source.android.com/devices/sensors/composite_sensors.html#counter and http://source.android.com/devices/sensors/composite_sensors.html#detector. A device that has the pedometer functionality this interface needs to support is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> |

iio: core: Introduce IIO_ACTIVITY channel
This channel will be used for exposing information about
activity composite sensors. Activities supported so far:
* running
* jogging
* walking
* still
THRESHOLD event is used to signal a change in the activity
state.
We associate a confidence interval for each activity expressed
as a percentage from 0 to 100.
* 0, means the sensor IS NOT reporting that activity.
* 100, means the sensor IS reporting that activity.
Users of this interface have two possible means to gather
information about the ongoing activities.
1. Event based, via event file descriptor
* sensor may report an event when ENTERING an activity or LEAVING
an activity based on a threshold value.
* drivers will wake up applications waiting data on the event fd
2. Polling, by reading the sysfs associated attribute files:
* /sys/bus/iio/devices/iio:device0/in_activity_running_input
expressed as percentage confidence value from 0 to 100.
This will offer an interface for Android significant motion
composite sensor defined here:
http://source.android.com/devices/sensors/composite_sensors.html
Activities listed above are supported by Freescale's MMA9553 sensor:

IB/srp: Add multichannel support
Improve performance by using multiple RDMA/RC channels per SCSI host for communication with an SRP target. About the implementation: - Introduce a loop over all channels in the code that uses target->ch. - Set the SRP_MULTICHAN_MULTI flag during login for the creation of the second and subsequent channels. - RDMA completion vectors are chosen such that RDMA completion interrupts are handled by the CPU socket that submitted the I/O request. As one can see in this patch it has been assumed if a system contains n CPU sockets and m RDMA completion vectors have been assigned to an RDMA HCA that IRQ affinity has been configured such that completion vectors [i*m/n..(i+1)*m/n) are bound to CPU socket i with 0 <= i < n. - Modify srp_free_ch_ib() and srp_free_req_data() such that it becomes safe to invoke these functions after the corresponding allocation function failed. - Add a ch_count sysfs attribute per target port.

drivers: base: support cpu cache information interface to userspace via sysfs
This patch adds initial support for providing processor cache information to userspace through sysfs interface. This is based on already existing implementations(x86, ia64, s390 and powerpc) and hence the interface is intended to be fully compatible. The main purpose of this generic support is to avoid further code duplication to support new architectures and also to unify all the existing different implementations. This implementation maintains the hierarchy of cache objects which reflects the system's cache topology. Cache devices are instantiated as needed as CPUs come online. The cache information is replicated per-cpu even if they are shared. A per-cpu array of cache information maintained is used mainly for sysfs-related book keeping. It also implements the shared_cpu_map attribute, which is essential for enabling both kernel and user-space to discover the system's overall cache topology. This patch also add the missing ABI documentation for the cacheinfo sysfs interface already, which is well defined and widely used.

PCI: Allow numa_node override via sysfs
NUMA systems with ACPI normally describe the physical topology via _PXM methods. But many BIOSes don't implement _PXM, which leaves the kernel with no way to discover the device topology, which reduces performance because we can't put memory and processes close to the device. The NUMA node of a PCI device is already exported in the sysfs "numa_node" file. Make that file writable so users can workaround the lack of _PXM methods in the BIOS. For example: echo 3 > /sys/devices/pci0000:ff/0000:03:1f.3/numa_node sets the node for PCI device 0000:03:1f.3. Writing the file emits a FW_BUG warning to encourage users to request firmware updates. It also taints the kernel with TAINT_FIRMWARE_WORKAROUND because overriding the node incorrectly can cause performance issues.

Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more perf updates from Ingo Molnar:
"A second (and last) round of late coming fixes and changes, almost all
of them in perf tooling:
User visible tooling changes:
- Add period data column and make it default in 'perf script' (Jiri
Olsa)
- Add a visual cue for toggle zeroing of samples in 'perf top'
(Taeung Song)
- Improve callchains when using libunwind (Namhyung Kim)
Tooling fixes and infrastructure changes:
- Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
- Fix off-by-one bugs in map->end handling (Stephane Eranian)
- Fix off-by-one bug in maps__find(), also related to map->end
handling (Namhyung Kim)
- Make struct symbol->end be the first addr after the symbol range,
to make it match the convention used for struct map->end. (Arnaldo
Carvalho de Melo)
- Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
live' (Jiri Olsa)
- Fix python test build by moving callchain_param to an object linked
into the python binding (Jiri Olsa)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- Do not include a struct hists per perf_evsel, untangling the
histogram code from perf_evsel, to pave the way for exporting a
minimalistic tools/lib/api/perf/ library usable by tools/perf and
initially by the rasd daemon being developed by Borislav Petkov,
Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo)
- Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
thread maps mean syswide monitoring, reducing the boilerplate for
tools that only want system wide mode. (Arnaldo Carvalho de Melo)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)
and other misc fixes"

Merge branch 'for-3.18/core' of git://git.kernel.dk/linux-block
Pull core block layer changes from Jens Axboe:
"This is the core block IO pull request for 3.18. Apart from the new
and improved flush machinery for blk-mq, this is all mostly bug fixes
and cleanups.
- blk-mq timeout updates and fixes from Christoph.
- Removal of REQ_END, also from Christoph. We pass it through the
->queue_rq() hook for blk-mq instead, freeing up one of the request
bits. The space was overly tight on 32-bit, so Martin also killed
REQ_KERNEL since it's no longer used.
- blk integrity updates and fixes from Martin and Gu Zheng.
- Update to the flush machinery for blk-mq from Ming Lei. Now we
have a per hardware context flush request, which both cleans up the
code should scale better for flush intensive workloads on blk-mq.
- Improve the error printing, from Rob Elliott.
- Backing device improvements and cleanups from Tejun.
- Fixup of a misplaced rq_complete() tracepoint from Hannes.
- Make blk_get_request() return error pointers, fixing up issues
where we NULL deref when a device goes bad or missing. From Joe
Lawrence.
- Prep work for drastically reducing the memory consumption of dm
devices from Junichi Nomura. This allows creating clone bio sets
without preallocating a lot of memory.
- Fix a blk-mq hang on certain combinations of queue depths and
hardware queues from me.
- Limit memory consumption for blk-mq devices for crash dump
scenarios and drivers that use crazy high depths (certain SCSI
shared tag setups). We now just use a single queue and limited
depth for that"

zram: use notify_free to account all free notifications
`notify_free' device attribute accounts the number of slot free
notifications and internally represents the number of zram_free_page()
calls. Slot free notifications are sent only when device is used as a
swap device, hence `notify_free' is used only for swap devices. Since

zram: report maximum used memory
Normally, zram user could get maximum memory usage zram consumed via polling mem_used_total with sysfs in userspace. But it has a critical problem because user can miss peak memory usage during update inverval of polling. For avoiding that, user should poll it with shorter interval(ie, 0.0000000001s) with mlocking to avoid page fault delay when memory pressure is heavy. It would be troublesome. This patch adds new knob "mem_used_max" so user could see the maximum memory usage easily via reading the knob and reset it via "echo 0 > /sys/block/zram0/mem_used_max".

zram: zram memory size limitation
Since zram has no control feature to limit memory usage, it makes hard to manage system memrory. This patch adds new knob "mem_limit" via sysfs to set up the a limit so that zram could fail allocation once it reaches the limit. In addition, user could change the limit in runtime so that he could manage the memory more dynamically. Initial state is no limit so it doesn't break old behavior.

PCI/MSI: Add "msi_bus" sysfs MSI/MSI-X control for endpoints
The "msi_bus" sysfs file for bridges sets a bus flag to allow or disallow future driver requests for MSI or MSI-X. Previously, the sysfs file existed for endpoints but did nothing. Add "msi_bus" support for endpoints, so an administrator can prevent the use of MSI and MSI-X for individual devices. Note that as for bridges, these changes only affect future driver requests for MSI or MSI-X, so drivers may need to be reloaded. Add documentation for the "msi_bus" sysfs file.

net_dma: simple removal
Per commit "77873803363c net_dma: mark broken" net_dma is no longer used
and there is no plan to fix it.
This is the mechanical removal of bits in CONFIG_NET_DMA ifdef guards.
Reverting the remainder of the net_dma induced changes is deferred to
subsequent patches.
Marked for stable due to Roman's report of a memory leak in
dma_pin_iovec_pages():

f2fs: give an option to enable in-place-updates during fsync to users
If user wrote F2FS_IPU_FSYNC:4 in /sys/fs/f2fs/ipu_policy, f2fs_sync_file only starts to try in-place-updates. And, if the number of dirty pages is over /sys/fs/f2fs/min_fsync_blocks, it keeps out-of-order manner. Otherwise, it triggers in-place-updates. This may be used by storage showing very high random write performance. For example, it can be used when, Seq. writes (Data) + wait + Seq. writes (Node) is pretty much slower than, Rand. writes (Data) Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |

1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.
Maintainer Updates * Add 3 designated reviewers for IIO. Lars, Peter and Hartmut have been actively reviewing a lot of patches for a while now so this reflects the status quo. These three are probably the only reason I keep my head above the water! New drivers and device support * max5821 DAC * Rockchip SARADC * TI ADC128S052 ADC * BMC150 Accelerometer * exynos ADC driver gains support for s3c24xx and s3c64xx parts. * kxcjk-1013 gainst range control and runtime PM support to drive down it's power usage. Driver removals * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple basis that they drivers just provided a register write function with no compliant user space ABI whatsoever. Much better to drop them and start again for these in the fullness of time. Core Enhancements * Join together neighbouring elements in the demux units that feeds the binary interfaces. This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJT86rcAAoJEFSFNJnE9BaIhKoQAKJ+pIpOb36k1Kjppe0PgQjG 0YCUJEte6z9RSM3s7Z47B6gm165MerYpscQW0GvTKCaxVB0GcnbE9IPYROIfZo+6 QIQbMHe9J7mYW0+qtHBxY5ItOCcVUMSwGfbXar8nFVS6266OcXP+HAau4U9WweKt GmYMuTxLdzm5JYh6C+ljv2PaRZ6B9IascF+YCrDnvkL34ojq7YpLA4QE0GcJlI4s Fz3k7UE0ckrrkAytCumjJC/zn/BSntzyUu2ctN5Z8VO6WeMyuSyFo8uxhzhoyjtm NnISm89Y2Dn5iBtb+QA/6OfOEd9MtjbALauozj70u6ONL0sYdbayNcHvhUU6lnNu hge8xlKS5MhCKtMFZ02qJM0MD/cajNt77m/QYaOoZlbuFPbREI12PtsHah6F7SJT Ad3YQ8T8rT+wzq45EqlqYE863H1OMMJulyjqUom0I8LgTijz+Exs6HWs4/qMhz6V 3T3ZwVoWSnhE4/yyRJFB/xD1P/uZIUGBP30EwlKxaiDmdxJ5X69Vlo9+AuecS3bq hRQvHSNFQG4cZEaDf/fzKGITkLv7V3oxqhg7yiSFtocj9kbF/6KyqgrUl5y7AZBL ZyW9m8OLr0K4ns8sKtRLeg9UmQ0Jxs2L1OvYtPSECAioMmMjLdij4Xt5U4Jv5ifC STIMv21b8mmNV9N8SdSo =zqHo -----END PGP SIGNATURE----- Merge tag 'iio-for-3.18a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into work-next Jonathan writes: 1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.

This cuts down on the number of individual copies needed when splitting out individual channels from the incoming channel scans. * Other demux related cleanups such as using roundup instead of a local implementation. Cleanups * Drop an unnecessary double setting of the owner field in xilinx adc. * Some more patches to use managed (devm) interfaces to cut down on complexity of removal code. * adis16060 coding style fixlets. * Fix some incorrect error returns in the Xilinx ADC driver. * Coding style fixlets for various accelerometer drivers. * Some sparse warning fixes to do with endianness and sign of variables. * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer in hid-sensor-magn-3d by dropping the relevant code. |
