Therefore, the recommended and only supported way of using NEON/VFP in the

kernel is by adhering to the following rules:

* isolate the NEON code in a separate compilation unit and compile it with

  '-mfpu=neon -mfloat-abi=softfp';

  '-march=armv7-a -mfpu=neon -mfloat-abi=softfp';

* issue the calls to kernel_neon_begin(), kernel_neon_end() as well as the calls

  into the unit containing the NEON code from a compilation unit which is *not*

  built with the GCC flag '-mfpu=neon' set.
