2016-07-14nvme: Remove RCU namespace protectionKeith Busch
We can't sleep with RCU read lock held, but we need to do potentially blocking stuff to namespace queues when iterating the list. This patch removes the RCU locking and holds a mutex instead. To prevent deadlocks, this patch removes holding the mutex during namespace scanning and removal. The unlocked namespace scanning is made safe by holding a reference to the namespace being scanned. List iteration that does IO has to be unlocked to allow error recovery. The caller must ensure the list can not be manipulated during such an event, so this patch adds a comment explaining this requirement to the only function that iterates an unlocked list. All callers currently meet this requirement, so no further changes required. List iterations that do not do IO can safely use the lock since it couldn't block recovery from missing forced IO completions.

2016-07-14i2c: core: Add function for finding the bus speed from ACPIJarkko Nikula
ACPI 5 specification doesn't have property for the I2C bus speed but I2cSerialBus resource descriptors which define each controller-slave connection define the maximum speed supported by that connection. Thus finding the maximum safe speed for the bus is to walk all I2cSerialBus resources that are associated to I2C controller and use the speed of slowest connection. Add function i2c_acpi_find_bus_speed() to the i2c-core that adapter drivers can call prior registering itself to core. This implies two-step walk through the I2cSerialBus resources: call to i2c_acpi_find_bus_speed() does the first scan and finds the safe bus speed that adapter drivers can set up. Adapter driver registration does the second scan when i2c-core creates the I2C slaves by calling the i2c_acpi_register_devices(). In that way the bus speed is set in case slave device probe gets called during registration and does communication. Implement this by reusing the existing ACPI I2C walk routines in the i2c-core. Extend them so that slowest connection speed is saved during the walk and I2C slaves are registered only when calling through the i2c_acpi_register_devices() with the i2c_adapter pointer.

What looked like bugs at the time (a 2nd allocation was triggered but failed, reset was called regardless of previous failures, and errors have not been reported to userspace) was actually something at least one userspace tool depended on.

The CONFIG_VIRT_CPU_ACCOUNTING_GEN irq time tracking code does not appear to currently work right. On CPUs without nohz_full=, only tick based irq time sampling is done, which breaks down when dealing with a nohz_idle CPU. On firewalls and similar systems, no ticks may happen on a CPU for a while, and the irq time spent may never get accounted properly. This can cause issues with capacity planning and power saving, which use the CPU statistics as inputs in decision making.

2016-07-14sched/cputime: Count actually elapsed irq & softirq timeRik van Riel
Currently, if there was any irq or softirq time during 'ticks' jiffies, the entire period will be accounted as irq or softirq time. This is inaccurate if only a subset of the time was actually spent handling irqs, and could conceivably mis-count all of the ticks during a period as irq time, when there was some irq and some softirq time. This can actually happen when irqtime_account_process_tick is called from account_idle_ticks, which can pass a larger number of ticks down all at once. Fix this by changing irqtime_account_hi_update(), irqtime_account_si_update(), and steal_account_process_ticks() to work with cputime_t time units, and return the amount of time spent in each mode. Rename steal_account_process_ticks() to steal_account_process_time(), to reflect that time is now accounted in cputime_t, instead of ticks. Additionally, have irqtime_account_process_tick() take into account how much time was spent in each of steal, irq, and softirq time. The latter could help improve the accuracy of cputime accounting when returning from idle on a NO_HZ_IDLE CPU. Properly accounting how much time was spent in hardirq and softirq time will also allow the NO_HZ_FULL code to re-use these same functions for hardirq and softirq accounting.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third set of IIO new device support, features and cleanups for the 4.8 cycle. New core features - Selection of the clock source for IIO timestamps. This is done per device as it makes little sense to have events in one timebase and data timestamped on another. Biggest reason for this is that we currently use a clock source which is non monotonic which can result in 'interesting' data sets. (Includes export for get_monotonic_corse64 which Thomas Gleixner didn't mind in an earlier version.) - MAINTAINERS add the git tree to the list for IIO. New device support + a kind of indirect staging graduation. * Broadcom iproc-static-adc - new driver * mcp4531 - support for MCP454x, MCP456x, MCP464x and MCP466x potentiometers * mpu6050 - support the IC20608 6 axis motion tracking device * st-sensors - support the lis3l02dq + drop the lis3l02dq driver from staging. The general purpose driver is missing event support, but good to get rid of this driver which was rather long in the tooth. New driver features * ak8975 - Add vid regulator support and refactor handling in general. - Allow a delay after enabling regulators. - Runtime and system PM. * bmg160 - filter frequency control support. * bmp280 - SPI device support. - EOC interrupt support for the BMP085 - power management support. - supply regulator support. - reset gpio support - dt bindings for reset gpio and regulators. - of table to support device tree registration * max1363 - Device tree bindings. * mcp4531 - Device tree bindings. * st-pressure - temperature channels as part of triggered buffer (previously not due probably to alignment issues - see below). - lps22hb open drain interrupt support. - lps22hb temperature channel support Cleanups and reworkings. * numerous ADC drivers - ensure the iio_dev->dev.of_node is set to the parent dev.of_node so as to allow client bindings to find the device. * ak8975 - Fix incorrect handling of missing regulator - make sure power is down and remove. * bmp280 - read the calibration data only once as it doesn't change. * isl29125 - Use a few macros to make code a touch more readable. * mma8452 - fix a memory leak on error. - drop an unecessary bit of return value handling. * potentiometer kconfig - typo fix. * st-pressure - drop some uninformative default assignments of elements of the channel array structure (aids readability). * st-sensors - Harden interrupt handling considerably. These are actually all using level interrupts, but at least two known boards have them wired to edge only interrupt chips. Hence a slightly interesting bit of handling is needed in which we first allow for the easy option (level triggered) and secondly check the status registers before reenabling edge interrupts and fall back to a tight loop in the thread until we successfully clear the interrupt. No harm is done if we never succeed in doing so. It's an odd patch that has been through a lot of revisions to reach a consensus on how to handle what is basically broken hardware (which the previous defaults allowed to kind of work). - Fix alignment to defined storagebytes boundaries. - Ensure alignment of power of 2 byte boundaries. This has always in theory been part of the ABI of IIO, but we missed a few that snuck in that need fixing. The effect was minor as they were only followed by timestamp channels which were correctly aligned, - Add some docs to explain the gain calculations.

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-testing Chanwoo writes: Update extcot://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon.git tags/extcon-next-for-4.8 n for 4.8 Detailed description for patchset: 1. Update the extcon-gpio.c driver - Use PM wakeirq APIs and support to check the state of external connector when wake-up from suspend state if the interrupt of external connector is not used as wakeup source. - Support for ACPI gpio interface 2. Remove deprecated extcon APIs using the legacy cable name - The extcon framework handle the external connector only by unique id instead of legacy cable name to prevent the problem. - Removed functions : extcon_get_cable_state() : extcon_set_cable_state() : extcon_register_interest() : extcon_unregister_interest() - It has the dependency on the axp288_charger.c driver. So, this pull request includes the 'ib-extcon-powersupply-4.8' immutable branch to protect the merge conflict. 3. Support the resource-managed function for extcon_register_notifier - Add the devm_extcon_register/unregister_notifier() funticon to handle the resource automatically by resource managed functions and split out the resource-managed function from extcon core to seprate file(devres.c). 4. Supprot the suspend/resume for extcon-adc-jack.c driver - Add the support the suspend/resume function to use extcon-adc-jack.c as wakeup source. 5. Fix the minor issue - Check the return value of find_cable_index_by_id() - Move the struct extcon_cable to extcon core from header file because it should be only handled on extcon core. - Add the missing of_node_put() after calling of_parse_phandle() to decrement the reference count.
