Kernel version numbers after 4.9.255 and 4.4.255

[Jari Ruusu]

Greg,
I hope that your linux kernel release scripts are
implemented in a way that understands that PATCHLEVEL= and
SUBLEVEL= numbers in top-level linux Makefile are encoded
as 8-bit numbers for LINUX_VERSION_CODE and
KERNEL_VERSION() macros, and must stay in range 0...255.
These 8-bit limits are hardcoded in both kernel source and
userspace ABI.

After 4.9.255 and 4.4.255, your scripts should be
incrementing a number in EXTRAVERSION= in top-level
linux Makefile.
