By the way, NX bit isn't the only option to disable data execution on x86/x86-64, there are also mechanism of segmentation but it's considered deprecated about 15 years ago and modern OS (both Linux and Windows) don't use it (or, to be more precise, use it in "Flat way" where are 4 segments identical in size and mapped on same physical memory location but different in access rights).
