%define common_desc_kernel The kernel package contains the Linux kernel (vmlinuz), the core of your \
Mageia operating system. The kernel handles the basic functions \
of the operating system: memory allocation, process allocation, device \
input and output, etc.

%define common_desc_kernel_smp This kernel relies on in-kernel smp alternatives to switch between up & smp \
mode depending on detected hardware. To force the kernel to boot in single \
processor mode, use the "nosmp" boot parameter.

The %{kname}-source package contains the source code files for the Mageia

own custom kernel that is better tuned to your particular hardware.

If you only want the files needed to build 3rdparty (nVidia, Ati, dkms-*,...)
drivers against, install the *-devel-* rpm that is matching your kernel.
