From 3b184b71dfcb156e08246f8fbe0cd088c6a6efed Mon Sep 17 00:00:00 2001 From: Vegard Nossum Date: Tue, 19 Dec 2023 16:11:59 +0100 Subject: x86/asm: Always set A (accessed) flag in GDT descriptors We have no known use for having the CPU track whether GDT descriptors have been accessed or not. Simplify the code by adding the flag to the common flags and removing it everywhere else.
