Make rodata strictly non-executable


Linux Kernel Configuration
└─>Make rodata strictly non-executable
In linux kernel since version 4 (release Date: 2015-04-12)  
If this is set, rodata will be made explicitly non-executable. This
provides protection on the rare chance that attackers might find and
use ROP gadgets that exist in the rodata section. This adds an
additional section-aligned split of rodata from kernel text so it
can be made explicitly non-executable. This padding may waste memory
space to gain the additional protection.
