From d293b20b840037211d9b43ded17901354e5204ad Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Fri, 2 Feb 2024 19:35:13 +0100 Subject: cpu/x86/Kconfig: Mark 64bit support as stable With SMM holding page tables itself, we can consider SMM support stable and safe enough for general use. Also update the respective documentation.
