*
* Part 1: The three most significant bytes represent the kernel's
* numeric version, x.y.z. These fields denote:
* x -- major release
* y -- minor release
* z -- patchlevel release
* Each of these elements must therefore be in the range 0 to 255, inclusive.
*
* Part 2: The least significant byte is reserved for future use.
