2016-01-01cpufreq: Simplify core code related to boost supportRafael J. Wysocki
Notice that the boost_supported field in struct cpufreq_driver is redundant, because the driver's ->set_boost callback may be left unset if "boost" is not supported. Moreover, the only driver populating the ->set_boost callback is acpi_cpufreq, so make it avoid populating that callback if "boost" is not supported, rework the core to check ->set_boost instead of boost_supported to verify "boost" support and drop boost_supported which isn't used any more.

ACPICA commit e4743959b59ad93eab7310adf756adc930be0ddb This reverts commit 8e7a8753827660c3dd1f571f3185610402b756f0. The _SUB method was found to be problematic for this interface because some implementations use control methods. Therefore, it is being removed. Operations cannot be used because this interface is called during the device discovery scan and the region handlers are not fully installed at that time.

2016-01-01ACPI / video: Add a acpi_video_handles_brightness_key_presses() helperHans de Goede
Several drivers want to know if the acpi-video is generating key-presses for brightness change hotkeys to avoid sending double key-events to userspace for these. Currently these driver use this construct for this: if (acpi_video_get_backlight_type() == acpi_backlight_vendor) report_brightness_key_event(); This indirect way of detecting if acpi-video is active does not make the code easier to understand, and in some cases it is wrong because just because the preferred type != vendor does not mean that acpi-video is actually listening for brightness events, e.g. there may be no acpi-video bus on the system at all. This commit adds a acpi_video_handles_brightness_key_presses() helper function, making the code needing this functionality both easier to read and more correct.

2015-12-30ASoC: Use nested lock for snd_soc_dapm_mutex_lockCharles Keepax
snd_soc_dapm_mutex_lock currently uses the un-nested call which can cause lockdep warnings when called from control handlers (a relatively common usage) and using modules. As creating the control causes a potential mutex inversion with the handler, creating the control will take the controls_rwsem under the dapm_mutex and accessing the control will take the dapm_mutex under controls_rwsem. All the users look like they want to be using the runtime class of the lock anyway, so this patch just changes snd_soc_dapm_mutex_lock to use the nested call, with the SND_SOC_DAPM_CLASS_RUNTIME class.

2015-12-29mm/vmstat: fix overflow in mod_zone_page_state()Heiko Carstens
mod_zone_page_state() takes a "delta" integer argument. delta contains the number of pages that should be added or subtracted from a struct zone's vm_stat field. If a zone is larger than 8TB this will cause overflows. E.g. for a zone with a size slightly larger than 8TB the line mod_zone_page_state(zone, NR_ALLOC_BATCH, zone->managed_pages); in mm/page_alloc.c:free_area_init_core() will result in a negative result for the NR_ALLOC_BATCH entry within the zone's vm_stat, since 8TB contain 0x8xxxxxxx pages which will be sign extended to a negative value. Fix this by changing the delta argument to long type. This could fix an early boot problem seen on s390, where we have a 9TB system with only one node. ZONE_DMA contains 2GB and ZONE_NORMAL the rest. The system is trying to allocate a GFP_DMA page but ZONE_DMA is completely empty, so it tries to reclaim pages in an endless loop. This was seen on a heavily patched 3.10 kernel. One possible explaination seem to be the overflows caused by mod_zone_page_state(). Unfortunately I did not have the chance to verify that this patch actually fixes the problem, since I don't have access to the system right now. However the overflow problem does exist anyway. Given the description that a system with slightly less than 8TB does work, this seems to be a candidate for the observed problem.

2015-12-29watchdog: Separate and maintain variables based on variable lifetimeGuenter Roeck
All variables required by the watchdog core to manage a watchdog are currently stored in struct watchdog_device. The lifetime of those variables is determined by the watchdog driver. However, the lifetime of variables used by the watchdog core differs from the lifetime of struct watchdog_device. To remedy this situation, watchdog drivers can implement ref and unref callbacks, to be used by the watchdog core to lock struct watchdog_device in memory. While this solves the immediate problem, it depends on watchdog drivers to actually implement the ref/unref callbacks. This is error prone, often not implemented in the first place, or not implemented correctly. To solve the problem without requiring driver support, split the variables in struct watchdog_device into two data structures - one for variables associated with the watchdog driver, one for variables associated with the watchdog core. With this approach, the watchdog core can keep track of its variable lifetime and no longer depends on ref/unref callbacks in the driver. As a side effect, some of the variables originally in struct watchdog_driver are now private to the watchdog core and no longer visible in watchdog drivers. As a side effect of the changes made, an ioctl will now always fail with -ENODEV after a watchdog device was unregistered with the character device still open. Previously, it would only fail with -ENODEV in some situations. Also, ioctl operations are now atomic from driver perspective. With this change, it is now guaranteed that the driver will not unregister a watchdog between a timeout change and the subsequent ping. The 'ref' and 'unref' callbacks in struct watchdog_driver are no longer used and marked as deprecated.

We are about to make a private copy of omapdss for omapfb and for omapdrm. The omapdss.h file will still be shared for the time being. The copy will need to change the config symbols, and we happen to have one use of these config symbols in omapdss.h which needs to be removed. Luckily we can just delete the use of CONFIG_OMAP2_DSS_VENC from omapdss, as it's used only to hide extern declarations, and there's no harm to have those declarations even if CONFIG_OMAP2_DSS_VENC is not set.

The big one here is the configfs support which has been a long time in the works but should allow for cleaner ways to do instantiation of those elements of IIO that aren't directly connected to specific hardware. Lots of cool new stuff we can use this for in the works! New core stuff (basically all configfs support related) * Configfs support - Core support (was waiting for a configfs patch that went in around 4.4rc2) - A little fixlet to add a configfs.h to contain a reference to the configfs_subsystem structure. * Some infrastructure to simplify handling of software based triggers (i.e. ones with no actual hardware associated with them) * A high resolution timer based trigger. This has been around for years but until the configfs support was ready we didn't have a sensible way of instantiating instances of it (the method used for the sysfs_trigger has never been really satisfactory) New Device Support * AMS iAQ Volatile Organic Compounds sensor support. * Freescale imx7d ADC driver * Maxim MAX30100 oximeter driver (note that for these devices most of the smart stuff will be in userspace - effectively they are just light sensors with some interesting led synchronization as far as the kernel is concerned). * Microchip mcp3421 support added to the mcp3422 driver. * TI adc124s021 support added to the adc128s052 driver. * TI ina219, inda226 power monitors. Note that there is an existing hwmon driver for these parts, the usecase is somewhat different so it is unclear at this point if the hwmon driver will eventually be replaced by a bridge from this driver. In the meantime the Kconfig dependencies should prevent both from being built. New driver functionality * us8152d power management support. Cleanups, fixups * Use list_for_each_entry_safe instead of list_for_each_safe with the entry bit coded longhand. * Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost when the driver was moved so lets do it again. * st-accel - drop an unused define. * vz89x, lidar - optimize i2c transactions by using a single i2c tranfers instead of multiple calls where supported (fall back to smbus calls as before if not). * Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency drivers instead of direct access to the structure element.
