Randomizes the virtual address space of kernel memory sections (physical
memory mapping, vmalloc & vmemmap) for x86_64. This security feature
mitigates exploits relying on predictable kernel addresses. These
addresses can be used to disclose the kernel modules base addresses or
corrupt specific str
