	  This option will re-use the same kernel sources as the one
	  that have been used for the kernel headers of the
	  cross-compiling toolchain. Having the same version for the
	  kernel running on the system and for the kernel headers is

	  download only one tarball of the kernel sources.

	  This option allows to use a specific 2.6.x or 2.6.x.y
	  official versions, as available on kernel.org
