Linux Kernel Configuration
└─>Processor type and features
└─>Randomize the kernel memory sections
In linux kernel since version 3.10 (release Date: 2013-06-30)  
Randomizes the base virtual address of kernel memory sections
(physical memory mapping, vmalloc & vmemmap). This security feature
makes exploits relying on predictable memory locations less reliable.

The order of allocations remains unchanged. Entropy is generated in
the same way as RANDOMIZE_BASE. Current implementation in the optimal
configuration have in average 30,000 different possible virtual
addresses for each memory section.

If unsure, say Y.
