ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

Pull dmaengine updates from Vinod Koul:
 "Fairly routine update this time around with all changes specific to
  drivers:

   - New driver for STMicroelectronics FDMA
   - Memory-to-memory transfers on dw dmac
   - Support for slave maps on pl08x devices
   - Bunch of driver fixes to use dma_pool_zalloc
   - Bunch of compile and warning fixes spread across drivers"

[ The ST FDMA driver already came in earlier through the remoteproc tree ]

Pull remoteproc updates from Bjorn Andersson:

 - introduce remoteproc "subdevice" support, which allows remoteproc
   driver to associate devices to the "running" state of the remoteproc,
   allowing devices to be probed and removed as the remote processor is
   booted, shut down or recovering from a crash.

 - handling of virtio device resources was improved, vring memory is now
   allocated as part of other memory allocation. This ensures that all
   vrings for all virtio devices are allocated before we boot the remote
   processor.

 - the debugfs mechanism for starting and stopping remoteproc instances
   was replaced with a sysfs interface, also providing a mechanism for
   specifying firmware to use by the instance. This allows user space to
   load and boot use case specific firmware on remote processors.

 - new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as
   removal of the unused StE modem loader.

 - finally support for crash recovery in the Qualcomm Wirelss subsystem
   (used for WiFi/BT/FM on a number of platforms) and a number of bug
   fixes and cleanups

Pull x86 idle updates from Ingo Molnar:
 "There were two bigger changes in this development cycle:

   - remove idle notifiers:

       32 files changed, 74 insertions(+), 803 deletions(-)

     These notifiers were of questionable value and the main usecase,
     the i7300 driver, was essentially unmaintained and can be removed,
     plus modern power management concepts don't need the callback - so
     use this golden opportunity and get rid of this opaque and fragile
     callback from a latency sensitive code path.

     (Len Brown, Thomas Gleixner)

   - improve the AMD Erratum 400 workaround that used high overhead MSR
     polling in the idle loop (Borisla Petkov, Thomas Gleixner)"
