From 7540f70df98f5c46feb5fe2257f93f543e5821e5 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 27 Nov 2023 13:00:53 +0100 Subject: [PATCH] arm64: Kconfig: drop KAISER reference from KPTI option description KAISER is a reference to the KASLR hardening technique that already existed before Meltdown happened, and by now, it is sufficiently obscure that mentioning it does not actually clarify anything. So remove this reference, and replace it with KPTI.
