From 746140625a0f6e8b6e16e999618d3236855a668c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 20 Apr 2022 16:44:17 +0300 Subject: [PATCH] Revert "ACPI: processor: idle: fix lockup regression on 32-bit ThinkPad T40" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit 20e582e16af24b074e583f9551fad557882a3c9d upstream. This reverts commit bfe55a1f7fd6bfede16078bf04c6250fbca11588. This was presumably misdiagnosed as an inability to use C3 at all when I suspect the real problem is just misconfiguration of C3 vs. ARB_DIS.
