Regarding the Raspberry Pi kernel version, what's the difference
between using the tip of the rpi-3.18.y branch and the tip of the
rpi-3.18.y-rebase branch? The kernel source code looks the same
between branches except for some trailing whitespace in files. Is the
rpi-3.18.y branch safe from rebases?
