From e1c8a3dc8aeee26e7d483669ca34fceb8e80d933 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Mon, 16 Sep 2024 12:56:06 +0100 Subject: [PATCH] x86/boot: Drop stale comment about zeroing the stack This used to be true, but was altered by commit 37786b23b027 ("x86/cet: Remove writeable mapping of the BSPs shadow stack") which moved cpu0_stack into .init.bss.stack_aligned.
