SUBLEVEL only has 8 bits of space, which means that we'll overflow it once it reaches 256. Few of the stable branches will imminently overflow SUBLEVEL while there's no risk of overflowing VERSION. Thus, give SUBLEVEL 8 more bits which will be stolen from VERSION, this should create a better balance between the different version numbers we use. We can't however use the original KERNEL_VERSION and LINUX_VERSION_CODE as userspace has created ABI dependency on their structure, and we risk breaking this userspace by modifying the layout of the version integers.

I wanted to re-use an older commit but forgot to drop the two tags above. The tags from Masahiro and Greg shouldn't be here, sorry about that. -- Thanks, Sasha
