2018-11-16iio: imu: st_lsm6dsx: add i2c embedded controller supportLorenzo Bianconi
i2c controller embedded in lsm6dx series can connect up to four slave devices using accelerometer sensor as trigger for i2c read/write operations. Introduce sensor hub support for lsm6dso sensor. Add register map for lis2mdl magnetometer sensor. In order to perform single read/write operations st_lsm6dsx driver relies on SLV0 channel (hw FIFO is not supported yet) Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

If we're polling for IO on a device that doesn't use interrupts, then IO completion loop (and wake of task) is done by submitting task itself. If that is the case, then we don't need to enter the wake_up_process() function, we can simply mark ourselves as TASK_RUNNING.

2018-11-16iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbersHans de Goede
Before this commit sensor_hub_input_attr_get_raw_value() failed to take the signedness of 16 and 8 bit values into account, returning e.g. 65436 instead of -100 for the z-axis reading of an accelerometer. This commit adds a new is_signed parameter to the function and makes all callers pass the appropriate value for this. While at it, this commit also fixes up some neighboring lines where statements were needlessly split over 2 lines to improve readability.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-11-14 This series contains updates to i40e and virtchnl. Lance Roy updates i40e to use lockdep_assert_held() instead of spin_is_locked(), since it is better suited to check locking requirements. Jan improves the code readability in XDP by adding the use of a local variable. Provides protection on methods that create/modify/destroy VF's via locking mechanism to prevent unstable behaviour and potential kernel panics. Krzysztof adds a hardware capability flag to indicate whether firmware supports stopping the LLDP agent. Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer is NULL terminated. Mitch fixes the issue of trying to start nway on devices that do not support auto-negotiation, by checking the autoneg state before attempting to restart nway. Alice updates virtchnl to keep the checks all together for ease of readability and consistency. Also fixed a "off by one" error in the number of traffic classes being calculated. Richard fixed VF port VLANs, where the priority bits were incorrectly set because the incorrect shift and mask bits were being used. Alan adds a bit to set and check if a timeout recovery is already pending to prevent overlapping transmit timeout recovery. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-11-15regulator: wm8994: Pass descriptor instead of GPIO numberLinus Walleij
Instead of passing a global GPIO number for the enable GPIO, pass a descriptor looked up from the device tree node or the board file decriptor table for the regulator. There is a single board file passing the GPIOs for LDO1 and LDO2 through platform data, so augment this to pass descriptors associated with the i2c device as well. The special GPIO enable DT property for the enable GPIO is nonstandard but this was accomodated in commit 6a537d48461deacc57c07ed86d9915e5aa4b3539 "gpio: of: Support regulator nonstandard GPIO properties".

2018-11-15rxrpc: Fix life checkDavid Howells
The life-checking function, which is used by kAFS to make sure that a call is still live in the event of a pending signal, only samples the received packet serial number counter; it doesn't actually provoke a change in the counter, rather relying on the server to happen to give us a packet in the time window. Fix this by adding a function to force a ping to be transmitted. kAFS then keeps track of whether there's been a stall, and if so, uses the new function to ping the server, resetting the timeout to allow the reply to come back. If there's a stall, a ping and the call is *still* stalled in the same place after another period, then the call will be aborted.

2018-11-15efi/arm: Defer persistent reservations until after paging_init()Ard Biesheuvel
The new memory EFI reservation feature we introduced to allow memory reservations to persist across kexec may trigger an unbounded number of calls to memblock_reserve(). The memblock subsystem can deal with this fine, but not before memblock resizing is enabled, which we can only do after paging_init(), when the memory we reallocate the array into is actually mapped. So break out the memreserve table processing into a separate routine and call it after paging_init() on arm64. On ARM, because of limited reviewing bandwidth of the maintainer, we cannot currently fix this, so instead, disable the EFI persistent memreserve entirely on ARM so we can fix it later.

2018-11-13platform/chrome: straighten out cros_ec_get_{next,host}_event() error codesBrian Norris
cros_ec_get_next_event() is documented to return 0 for success and negative for errors. It currently returns negative for some errors, and non-negative (number of bytes received) for success (including some "no data available" responses as zero). This mostly works out OK, because the callers were more or less ignoring the documentation, and only treating positive values as success (and indepdently checking the modification of 'wakeup'). Let's button this up by avoiding pretending to handle event/wakeup distinctions when no event info was retrieved (i.e., returned 0 bytes). And fix the documentation of cros_ec_get_host_event() and cros_ec_get_next_event() to accurately describe their behavior.

2018-11-13fanotify: introduce new event mask FAN_OPEN_EXEC_PERMMatthew Bobrowski
A new event mask FAN_OPEN_EXEC_PERM has been defined. This allows users to receive events and grant access to files that are intending to be opened for execution. Events of FAN_OPEN_EXEC_PERM type will be generated when a file has been opened by using either execve(), execveat() or uselib() system calls. This acts in the same manner as previous permission event mask, meaning that an access response is required from the user application in order to permit any further operations on the file.

2018-11-13fanotify: introduce new event mask FAN_OPEN_EXECMatthew Bobrowski
A new event mask FAN_OPEN_EXEC has been defined so that users have the ability to receive events specifically when a file has been opened with the intent to be executed. Events of FAN_OPEN_EXEC type will be generated when a file has been opened using either execve(), execveat() or uselib() system calls. The feature is implemented within fsnotify_open() by generating the FAN_OPEN_EXEC event type if __FMODE_EXEC is set within file->f_flags.
