2016-09-15tty: serial_core: add tty NULL check to uart_tx_stoppedRob Herring
Commit 761ed4a94582 ("tty: serial_core: convert uart_close to use tty_port_close") created a case where a port used for a console does not get shutdown on tty closing. Then a call to uart_tx_stopped() segfaults because the tty is NULL. This could be fixed to restore old behavior, but we also want to allow tty_ports to work without a tty attached. So this change to allow a NULL tty_struct is needed either way.

2016-09-15sched/core: Allow putting thread_info into task_structAndy Lutomirski
If an arch opts in by setting CONFIG_THREAD_INFO_IN_TASK_STRUCT, then thread_info is defined as a single 'u32 flags' and is the first entry of task_struct. thread_info::task is removed (it serves no purpose if thread_info is embedded in task_struct), and thread_info::cpu gets its own slot in task_struct. This is heavily based on a patch written by Linus.

2016-09-15ALSA: rename TLV-related macros so that they're friendly to user applicationsTakashi Sakamoto
In a previous commit, some macros newly appeared to UAPI header for TLV packet. These macros have short names and they easily bring name conflist to applications. The conflict can be avoided to rename them with a proper prefix. For this purpose, this commit renames these macros with prefix 'SNDRV_CTL_TLVD_'.

2016-09-15ALSA: control: move layout of TLV payload to UAPI headerTakashi Sakamoto
In ALSA control interface, each element set can have threshold level information. This information is transferred between drivers/applications, in a shape of tlv packet. The layout of this packet is defined in 'uapi/sound/asound.h' (struct snd_ctl_tlv): struct snd_ctl_tlv { unsigned int numid; unsigned int length; unsigned int tlv[0]; }; Data in the payload (struct snd_ctl_tlv.tlv) is expected to be filled according to our own protocol. This protocol is described in 'include/sound/tlv.h'. A layout of the payload is expected as: struct snd_ctl_tlv.tlv[0]: one of SNDRV_CTL_TLVT_XXX struct snd_ctl_tlv.tlv[1]: Length of data struct snd_ctl_tlv.tlv[2...]: data Unfortunately, the macro is not exported to user land yet, thus applications cannot get to know the protocol. Additionally, ALSA control core has a feature called as 'user-defined' element set. This allows applications to add/remove arbitrary element sets with elements to control devices. Elements in the element set can be operated by the same way as the ones added by in-kernel implementation. For threshold level information of 'user-defined' element set, applications need to register the information to an element set. However, as described above, layout of the payload is closed in kernel land. This is quite inconvenient, too. This commit moves the protocol to UAPI header for TLV.

2016-09-14genirq/affinity: Provide smarter irq spreading infrastructureThomas Gleixner
The current irq spreading infrastructure is just looking at a cpumask and tries to spread the interrupts over the mask. Thats suboptimal as it does not take numa nodes into account. Change the logic so the interrupts are spread across numa nodes and inside the nodes. If there are more cpus than vectors per node, then we set the affinity to several cpus. If HT siblings are available we take that into account and try to set all siblings to a single vector.

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.

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 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.

2016-09-14blk-mq: introduce blk_mq_delay_kick_requeue_list()Mike Snitzer
blk_mq_delay_kick_requeue_list() provides the ability to kick the q->requeue_list after a specified time. 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).

2016-09-14block: Improve bio_set_op_attrs() robustnessBart Van Assche
Since REQ_OP_BITS == 3 and __REQ_NR_BITS == 30 it is not that hard to pass an op_flags argument to bio_set_op_attrs() that is larger than the number of bits reserved for the op_flags argument. Complain if this happens. Additionally, ensure that negative arguments trigger a complaint (1 << ... is signed while 1U << ... is unsigned; adding 0U to an integer expression causes it to be promoted to an unsigned type).

In order to help determine the effectiveness of polling in a running system it is usful to determine the ratio of how often the poll function is called vs how often the completion is checked.
