The Linux Kernel: Configuring the Kernel Part 5

The next kernel feature that can be configured is a x86 random number generator (x86 architectural random number generator (ARCH_RANDOM)). Remember, we are configuring the kernel source code for an AMD64 system. This number generator uses the x86 RDRAND instructions for Intel processors. It is not necessary for general use, so I will disable this for a more lightweight kernel.
