I called protection keys: X86_INTEL_MEMORY_PROTECTION_KEYS AMD recently posted documentation which shows them implementing it as well. The "INTEL_" is feeling now like a mistake. Going forward, we should probably avoid sticking the company name on them, if for no other reason than avoiding confusion and/or churn in the future. Shadow stacks, for instance, seem like something that another vendor might implement one day. So, let's at least remove the "INTEL_" from the config option names themselves. Mentioning Intel in the changelog and the Kconfig help text is fine.
