From 5bc66170dc486556a1e36fd384463536573f4b82 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Thu, 18 Oct 2012 15:10:56 +0200 Subject: [PATCH] x86, MCE: Remove bios_cmci_threshold sysfs attribute 450cc201038f3 ("x86/mce: Provide boot argument to honour bios-set CMCI threshold") added the bios_cmci_threshold sysfs attribute which was supposed to communicate to userspace tools that BIOS CMCI threshold has been honoured. However, this info is not of any importance to userspace - it should rather get the actual error count it has been thresholded already from MCi_STATUS[38:52]. So drop this before it becomes a used interface (good thing we caught this early in 3.7-rc1, right after the merge window closed). Cc: Naveen N.
