[OE-core] [PATCH 1/2] kernel-headers: linux kernel headers

[Juro Bystricky]

Header files and scripts for building modules for Linux kernel.

A set of files is needed to allow building new Linux kernel modules
against an already installed Linux kernel. The files include various
header files, script files, Makefiles, source code files for several
utility programs and Linux kerenl .config file.

The files may be needed by programs such as:
    dkms, nvidia-304xx-dkms, virtualbox, acpi_call, audit,
    bbswitch, ipsec-tools, nvidia-304xx, nvidia-340xx, openssh,
    r8168, rt3562sta, sysprof, tp_smapi, vhba-module, kmod, ...
