From 7f1b8e0d6360178e3527d4f14e6921c254a86035 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 20 Dec 2021 21:43:28 +0100 Subject: x86/mce: Remove the tolerance level control This is pretty much unused and not really useful. What is more, all relevant MCA hardware has recoverable machine checks support so there's no real need to tweak MCA tolerance levels in order to *maybe* extend machine lifetime. So rip it out.
