Update to 3.15-rc7.
    - Eliminated 1 patch.
    - Config changes:
      - CX_ECAT=m (default n) for i386/x86_64
        - The vendor supplying this hardware only uses 32/64-bit Atom CPUs.
          This may need to be revisited if the hardware extends to different
          architectures (ARM, probably).
      - SENSORS_NTC_THERMISTOR=m (default n)
        - Sensor chip that could be found essentially anywhere.
