	  Select the kernel version to get headers from.

	  The kernel headers must be at least as old as the oldest kernel
	  you intend to run on your target.

	  If you use Buildroot to build a kernel, then you can use
	  the sources from that kernel as source for the headers.

	  If you choose a custom version of the kernel headers, or choose
	  to use the same sources as the kernel, you'll have to select
	  (below) the series of that kernel, so that Buildroot can show
	  or hide packages that have strong requirements on the kernel
	  headers.
