From 36d4fe147c870f6d3f6602befd7ef44393a1c87a Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Wed, 10 Apr 2024 22:40:50 -0700 Subject: x86/bugs: Remove CONFIG_BHI_MITIGATION_AUTO and spectre_bhi=auto Unlike most other mitigations' "auto" options, spectre_bhi=auto only mitigates newer systems, which is confusing and not particularly useful. Remove it.
