Preparing to compile for kernel version 4.13.0

***WARNING:*** You do not have the full kernel sources installed.
This does not prevent you from building the v4l-dvb tree if you have the
kernel headers, but the full kernel source may be required in order to use
make menuconfig / xconfig / qconfig.

If you are experiencing problems building the v4l-dvb tree, please try
building against a vanilla kernel before reporting a bug.

Vanilla kernels are available at http://kernel.org.
On most distros, this will compile a newly downloaded kernel:

cp /boot/config-`uname -r` <your kernel dir>/.config
cd <your kernel dir>
make all modules_install install

Please see your distro's web site for instructions to build a new kernel.

WARNING: This is the V4L/DVB backport tree, with experimental drivers
	 backported to run on legacy kernels from the development tree at:
		http://git.linuxtv.org/media-tree.git.
	 It is generally safe to use it for testing a new driver or
	 feature, but its usage on production environments is risky.
	 Don't use it in production. You've been warned.
