Description:

The kernel package contains the Linux kernel (vmlinuz), the core of your
Mandriva Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc. This kernel is compiled for server use, single or
multiple x86_64 processor(s)/core(s), using no preempt, HZ_100,
CFS cpu scheduler and cfq i/o scheduler.
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.
