I suggest saturating at KERNEL_VERSION at xxxxFF.

Code which needs to care about versions after 255 can check LINUX_VERSION_SUBLEVEL directly.

That seems to be the best thing to be done.

Without that, media applications will break, as they several of them rely at the Kernel version in order to enable some features:

drivers/media/cec/core/cec-api.c: caps.version = LINUX_VERSION_CODE;
drivers/media/mc/mc-device.c: info->media_version = LINUX_VERSION_CODE;
drivers/media/v4l2-core/v4l2-ioctl.c: cap->version = LINUX_VERSION_CODE;
drivers/media/v4l2-core/v4l2-subdev.c: cap->version = LINUX_VERSION_CODE;
