2016-09-14genirq/msi: Add cpumask allocation to alloc_msi_entryThomas Gleixner
For irq spreading want to store affinity masks in the msi_entry. Add the infrastructure for it. We allocate an array of cpumasks with an array size of the number of used vectors in the entry, so we can hand in the information per linux interrupt later. As we hand in the number of used vectors, we assign them right away. Convert all the call sites.

2016-09-14list: Expand list_first_entry_or_null()Chris Wilson
Due to the use of READ_ONCE() in list_empty() the compiler cannot optimise !list_empty() ? list_first_entry() : NULL very well. By manually expanding list_first_entry_or_null() we can take advantage of the READ_ONCE() to avoid the list element changing under the test while the compiler can generate smaller code.

New device support * ad8801 dac - new driver supporting ad8801 and ad8803 DACs. * adc12138 - new driver supporting TI adc12130/adc12132 and adc12138 ADCs. * ltc2485 adc - new driver * mxc6255 - add support for the mxc6225 part name and fixup the ID check so it works. * vz89x VOC sensor - add support for the vz89te part which drops the voc_short channel and adds CRCs compared to other supported parts. New features * core - immutable triggers. These effectively grant exclusive control over a trigger. The typical usecase is a device representing an analog part (perhaps a MUX) that needs to control the sampling of a downstream ADC. - resource managed trigger registration and triggered_buffer_init. - iio_push_event now protected against case of the event interface registration not having yet occured. Only matters if an interrupt can occur during this window - might happen on shared interrupt lines. - helper to let a driver query if the trigger it is using is provided by itself (using the convention of both device and trigger having the same parent). * tools - iio-utils. Used channel modifier scaling in preference to generic scaling when both exist. * at91-adc - Add support for touchscreen switches closure time needed by some newer parts. * stx104 - support the ADC channels on this ADC/DAC board. As these are the primary feature of the board also move the driver to the iio/adc directory. * sx9500 - device tree bindings. Cleanups / Fixes * ad5755 - fix an off-by-one on devnr limit check (introduced earlier this cycle) * ad7266 - drop NULL check on devm_regulator_get_optional as it can't return NULL. * ak8974 - avoid an unused functional warning due to rework in PM core code. - remove .owner field setting as done by i2c_core. * ina2xx - clear out a left over debug field from chip global data. * hid-sensors - avoid an unused functional warning due to rework in PM core code. * maxim-thermocouple - fix non static symbol warnings. * ms5611 - fetch and enable regulators unconditionally when they aren't optional. * sca3000 - whitespace cleanup. * st_sensors - fetch and enable regulators unconditionally rather than having them supported as optional regulators (missunderstanding on my part amongst others a while back) - followup to previous patch fixes error checking on the regulators. - mark symbols static where possible. - use the 'is it my trigger' help function. This prevents the odd case of another device triggering from the st-sensors trigger whilst the st-sensors trigger is itself not using it but rather using say an hrtimer. * ti-ads1015 - add missing of_node_put. * vz89x - rework to all support of new devices. - prevent reading of a corrupted buffer. - fixup a return value of 0/1 in a bool returning function. Address updates - Vlad Dogaru email address change.

As for UDC drivers, only dwc3 (26.5%) and dwc2 (12.7%) have really been active. The most important changes for dwc3 are better support for scatterlist and, again, throughput improvements. While on dwc2 got some minor stability fixes related to soft reset and FIFO usage. Felipe Tonello has done some good work fixing up our f_midi gadget and Tal Shorer has implemented a nice API change for our ULPI bus. Apart from these, we have our usual set of non-critical fixes, spelling fixes, build warning fixes, etc.

2016-09-14dm rq: add DM_MAPIO_DELAY_REQUEUE to delay requeue of blk-mq requestsMike Snitzer
Otherwise blk-mq will immediately dispatch requests that are requeued via a BLK_MQ_RQ_QUEUE_BUSY return from blk_mq_ops .queue_rq. Delayed requeue is implemented using blk_mq_delay_kick_requeue_list() with a delay of 5 secs. In the context of DM multipath (all paths down) it doesn't make any sense to requeue more quickly.

To do this the request_queue's 'requeue_work' member was changed to a delayed_work. blk_mq_delay_kick_requeue_list() allows DM to defer processing requeued requests while it doesn't make sense to immediately requeue them (e.g. when all paths in a DM multipath have failed).

2016-09-14genirq: Expose interrupt information through sysfsCraig Gallek
Information about interrupts is exposed via /proc/interrupts, but the format of that file has changed over kernel versions and differs across architectures. It also has varying column numbers depending on hardware. That all makes it hard for tools to parse. To solve this, expose the information through sysfs so each irq attribute is in a separate file in a consistent, machine parsable way. This feature is only available when both CONFIG_SPARSE_IRQ and CONFIG_SYSFS are enabled. Examples: /sys/kernel/irq/18/actions: i801_smbus,ehci_hcd:usb1,uhci_hcd:usb7 /sys/kernel/irq/18/chip_name: IR-IO-APIC /sys/kernel/irq/18/hwirq: 18 /sys/kernel/irq/18/name: fasteoi /sys/kernel/irq/18/per_cpu_count: 0,0 /sys/kernel/irq/18/type: level /sys/kernel/irq/25/actions: ahci0 /sys/kernel/irq/25/chip_name: IR-PCI-MSI /sys/kernel/irq/25/hwirq: 512000 /sys/kernel/irq/25/name: edge /sys/kernel/irq/25/per_cpu_count: 29036,0 /sys/kernel/irq/25/type: edge [ tglx: Moved kobject_del() under sparse_irq_lock, massaged code comments and changelog ] Signed-off-by: Craig Gallek <kraig@google.com> Cc: David Decotigny <decot@google.com> Link: http://lkml.kernel.org/r/1473783291-122873-1-git-send-email-kraigatgoog@gmail.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2016-09-13cpufreq / sched: SCHED_CPUFREQ_IOWAIT flag to indicate iowait conditionRafael J. Wysocki
Testing indicates that it is possible to improve performace significantly without increasing energy consumption too much by teaching cpufreq governors to bump up the CPU performance level if the in_iowait flag is set for the task in enqueue_task_fair(). For this purpose, define a new cpufreq_update_util() flag SCHED_CPUFREQ_IOWAIT and modify enqueue_task_fair() to pass that flag to cpufreq_update_util() in the in_iowait case. That generally requires cpufreq_update_util() to be called directly from there, because update_load_avg() may not be invoked in that case. Signed-off-by: Rafael J.

Support the extcon property and add the synchronization APIs. - This feature supports the extcon property for external connector because each external connector might have the property according to the H/W design. - The property name should keep the following style. : EXTCON_PROP_USB_[property_name] : EXTCON_PROP_CHG_[property_name] : EXTCON_PROP_JACK_[property_name] : EXTCON_PROP_DISP_[property_name] - Add the new extcon APIs to support the extcon property. : extcon_set_property() : extcon_get_property() : extcon_set_property_capability() : extcon_get_property_capability() - Add the new synchronization extcon APIs. : This feature adds the synchronization extcon APIs to support the noti for both state and property. When extcon_*_sync() functions is called, the extcon informs the information from extcon provider to extcon client. The extcon driver may need to change the both state and multiple properties at the same time. After setting the data of a external connector, the extcon send the notification to client driver with the extcon_*_sync(). : extcon_sync() : extcon_set_state_sync() : extcon_set_property_sync() - Change the name of existing APIs. : extcon_set_cable_state_() -> extcon_set_cable() : extcon_get_cable_state_() -> extcon_get_cable() 2. Add the extcon type to group the connector into five category. - EXTCON_TYPE_USB : USB connector - EXTCON_TYPE_CHG : Charger connector - EXTCON_TYPE_JACK : Jack connector - EXTCON_TYPE_DISP : Display connector - EXTCON_TYPE_MISC : Miscellaneous connector 3. Add the new property for external connector. - EXTCON_PROP_USB_VBUS - EXTCON_PROP_USB_TYPEC_POLARITY - EXTCON_PROP_USB_SS (SuperSpeed) - EXTCON_PROP_DISP_HPD (Hot Plug Detect) 4. Add the new type of external connector. - EXTCON_DISP_DP : Display Port - EXTCON_DISP_HMD : Head Mounted Device - EXTCON_CHG_WPT : Wireless Power Transfer device 5. Add the new extcon driver. - Qualcomm SPMI PMIC USB id detection driver detects whether EXTCON_USB_HOST is attached or detached. (extcon-qcom-spmi-mis.c) 6. Remove the usage of extcon_update_state() and old extcon_set_state() - Both extcon_update_state() and extcon_set_state() should change the state of all external connectors with bit masking handling. It may occur the problem. Instead, extcon provides the extcon_set/get_state() functions. 7. Fix the minor issues on extcon drivers.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for your net tree, they are: 1) Endianess fix for the new nf_tables netlink trace infrastructure, NFTA_TRACE_POLICY endianess was not correct, patch from Liping Zhang. 2) Fix broken re-route after userspace queueing in nf_tables route chain. This patch is large but it is simple since it is just getting this code in sync with iptable_mangle. Also from Liping. 3) NAT mangling via ctnetlink lies to userspace when nf_nat_setup_info() fails to setup the NAT conntrack extension. This problem has been there since the beginning, but it can now show up after rhashtable conversion. 4) Fix possible NULL pointer dereference due to failures in allocating the synproxy and seqadj conntrack extensions, from Gao feng. ==================== Signed-off-by: David S.

The MCA_IPID register uniquely identifies a bank's type and instance on Scalable MCA systems. We should save the value of this register in struct mce along with the other relevant error information. This ensures that we can decode errors without relying on system software to correlate the bank to the type.
