2015-05-27phy: sun4i-usb: Add a sunxi specific function for setting squelch-detectHans de Goede
The sunxi otg phy has a bug where it wrongly detects a high speed squelch when reset on the root port gets de-asserted with a lo-speed device. The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Add a sunxi specific phy function to allow the sunxi-musb glue to do this.

2015-05-27perf: allow for PMU-specific event filteringMark Rutland
In certain circumstances it may not be possible to schedule particular events due to constraints other than a lack of hardware counters (e.g. on big.LITTLE systems where CPUs support different events). The core perf event code does not distinguish these cases and pessimistically assumes that any failure to schedule an event means that it is not worth attempting to schedule later events, even if some hardware counters are still unused. When an event a pmu cannot schedule exists in a flexible group list it can unnecessarily prevent event groups following it in the list from being scheduled (until it is rotated to the end of the list). This means some events are scheduled for only a portion of the time they could be, and for short running programs no events may be scheduled if the list is initially sorted in an unfortunate order. This patch adds a new (optional) filter_match function pointer to struct pmu which a pmu driver can use to tell perf core when an event matches pmu-specific scheduling requirements. This plugs into the existing event_filter_match logic, and makes it possible to avoid the scheduling problem described above. When no filter is provided by the PMU, the existing behaviour is retained.

2015-05-27perf/x86: Fix event/group validationPeter Zijlstra
Commit 43b4578071c0 ("perf/x86: Reduce stack usage of x86_schedule_events()") violated the rule that 'fake' scheduling; as used for event/group validation; should not change the event state. This went mostly un-noticed because repeated calls of x86_pmu::get_event_constraints() would give the same result. And x86_pmu::put_event_constraints() would mostly not do anything. Commit e979121b1b15 ("perf/x86/intel: Implement cross-HT corruption bug workaround") made the situation much worse by actually setting the event->hw.constraint value to NULL, so when validation and actual scheduling interact we get NULL ptr derefs. Fix it by removing the constraint pointer from the event and move it back to an array, this time in cpuc instead of on the stack. validate_group() x86_schedule_events() event->hw.constraint = c; # store <context switch> perf_task_event_sched_in() ... x86_schedule_events(); event->hw.constraint = c2; # store ... put_event_constraints(event); # assume failure to schedule intel_put_event_constraints() event->hw.constraint = NULL; <context switch end> c = event->hw.constraint; # read -> NULL if (!test_bit(hwc->idx, c->idxmsk)) # <- *BOOM* NULL deref This in particular is possible when the event in question is a cpu-wide event and group-leader, where the validate_group() tries to add an event to the group.

2015-05-26sched, cgroup: replace signal_struct->group_rwsem with a global percpu_rwsemTejun Heo
The cgroup side of threadgroup locking uses signal_struct->group_rwsem to synchronize against threadgroup changes. This per-process rwsem adds small overhead to thread creation, exit and exec paths, forces cgroup code paths to do lock-verify-unlock-retry dance in a couple places and makes it impossible to atomically perform operations across multiple processes. This patch replaces signal_struct->group_rwsem with a global percpu_rwsem cgroup_threadgroup_rwsem which is cheaper on the reader side and contained in cgroups proper. This patch converts one-to-one. This does make writer side heavier and lower the granularity; however, cgroup process migration is a fairly cold path, we do want to optimize thread operations over it and cgroup migration operations don't take enough time for the lower granularity to matter.

2015-05-26sched, cgroup: reorganize threadgroup lockingTejun Heo
threadgroup_change_begin/end() are used to mark the beginning and end of threadgroup modifying operations to allow code paths which require a threadgroup to stay stable across blocking operations to synchronize against those sections using threadgroup_lock/unlock(). It's currently implemented as a general mechanism in sched.h using per-signal_struct rwsem; however, this never grew non-cgroup use cases and becomes noop if !CONFIG_CGROUPS. It turns out that cgroups is gonna be better served with a different sycnrhonization scheme and is a bit silly to keep cgroups specific details as a general mechanism. What's general here is identifying the places where threadgroups are modified. This patch restructures threadgroup locking so that threadgroup_change_begin/end() become a place where subsystems which need to sycnhronize against threadgroup changes can hook into. cgroup_threadgroup_change_begin/end() which operate on the per-signal_struct rwsem are created and threadgroup_lock/unlock() are moved to cgroup.c and made static. This is pure reorganization which doesn't cause any functional changes. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Ingo Molnar <mingo@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org>

2015-05-26usb: phy: Add interface to get phy give of device_node.NeilBrown
Split the "get phy from device_node" functionality out of "get phy by phandle" so it can be used directly. This is useful when a battery-charger is intimately associated with a particular phy but handled by a separate driver. The charger can find the device_node based on sibling relationships without the need for a redundant declaration in the devicetree description. As a peripheral that gets a phy will often want to register a notifier block, and de-register it later, that functionality is included so the de-registration is automatic.

2015-05-26dmaengine: pxa: add pxa dmaengine driverRobert Jarzmik
This is a new driver for pxa SoCs, which is also compatible with the former mmp_pdma. The rationale behind a new driver (as opposed to incremental patching) was : - the new driver relies on virt-dma, which obsoletes all the internal structures of mmp_pdma (sw_desc, hw_desc, ...), and by consequence all the functions - mmp_pdma allocates dma coherent descriptors containing not only hardware descriptors but linked list information The new driver only puts the dma hardware descriptors (ie. 4 u32) into the dma pool allocated memory. This changes completely the way descriptors are handled - the architecture behind the interrupt/tasklet management was rewritten to be more conforming to virt-dma - the buffers alignment is handled differently The former driver assumed that the DMA channel stopped between each descriptor. The new one chains descriptors to let the channel running. This is a necessary guarantee for real-time high bandwidth usecases such as video capture on "old" architectures such as pxa. - hot chaining / cold chaining / no chaining Whenever possible, submitting a descriptor "hot chains" it to a running channel. There is still no guarantee that the descriptor will be issued, as the channel might be stopped just before the descriptor is submitted. Yet this allows to submit several video buffers, and resubmit a buffer while another is under handling. As before, dma_async_issue_pending() is the only guarantee to have all the buffers issued. When an alignment issue is detected (ie. one address in a descriptor is not a multiple of 8), if the already running channel is in "aligned mode", the channel will stop, and restarted in "misaligned mode" to finished the issued list. - descriptors reusing A submitted, issued and completed descriptor can be reused, ie resubmitted if it was prepared with the proper flag (DMA_PREP_ACK). Only a channel resources release will in this case release that buffer. This allows a rolling ring of buffers to be reused, where there are several thousands of hardware descriptors used (video buffer for example). Additionally, a set of more casual features is introduced : - debugging traces - lockless way to know if a descriptor is terminated or not The driver was tested on zylonite board (pxa3xx) and mioa701 (pxa27x), with dmatest, pxa_camera and pxamci.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new driver, functionality and cleanups for IIO in the 4.2 cycle. Core functionality * i and q modifiers from quadrature channels. * IIO_CHAN_INFO_OVERSAMPLING_RATIO added. * High pass filter attributes added to mirror the existing low pass filter ones. Core cleanups * Make IIO tools building more cross compiler friendly. * Substantial rework of the function __iio_update_buffers to greatly simplify a hideously evolved function. New drivers and support * ACPI0008 ambient light sensor driver. This one has been around a long time to will be good to finally get it into mainline. * Berlin SOC ADC support. * BMC150 magnetometer. The accelerometer in the same package has been supported for quite some time, so good to have this half as well. * m62332 DAC driver * MEMSIC MMC35420 magnetometer. * ROHM BH1710 and similar ambient light sensors. * Sensortek STK3310 light sensor. * Sensortek STK8312 accelerometer. * Sensortek STK8BA50 accelerometer. * ti-adc128s052 gains support form the adc122s021 2 channel ADC. Driver cleanups and functionality. * Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled. * bmc150 - decouple trigger from buffer to allow other triggers to be used. * bmg160 - decouple trigger from buffer to allow other triggers to be used. Fix a trivial unused field. * Constify a load of platform_device_id structures. * inv_mpu6050 - device tree bindings. * hid-sensors - fix a memory leak during probe if certain errors occur. * ltr501 - illuminance channel derived (in an non obvious fashion) from the intensity channels. * ltr501 - fix a boundary check on the proximity threshold. * mlx90614 - drop a pointless return. * mma8452 - Debugfs register access and fix a bug that had no effect (by coincidence) * ti_am335x_adc - add device tree bindings for sample-delay, open-delay and averaging. The ideal settings for these tend to be board design specific.

Refine the mechanism introduced by commit f244d8b623da ("ACPIPHP / radeon / nouveau: Fix VGA switcheroo problem related to hotplug") to propagate the ignore_hotplug setting of the device to its parent bridge in case hotplug notifications related to the graphics adapter switching are given for the bridge rather than for the device itself (they need to be ignored in both cases).

In order to prepare for the next few commits, that will stop migrating sysfs files on cpu hotplug, this patch starts managing sysfs-cpu separately. The behavior is still the same as we are still migrating sysfs files on hotplug, later commits would change that.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contain Netfilter fixes for your net tree, they are: 1) Fix a race in nfnetlink_log and nfnetlink_queue that can lead to a crash. This problem is due to wrong order in the per-net registration and netlink socket events. Patch from Francesco Ruggeri. 2) Make sure that counters that userspace pass us are higher than 0 in all the x_tables frontends. Discovered via Trinity, patch from Dave Jones. 3) Revert a patch for br_netfilter to rely on the conntrack status bits. This breaks stateless IPv6 NAT transformations.
