%define common_desc_kernel The kernel package contains the Linux kernel (vmlinuz), the core of your \
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.
