[PATCH 5.8 51/70] x86/traps: Fix #DE Oops message regression
From: Greg Kroah-Hartman
Date: Sat Oct 31 2020 - 07:43:29 EST
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
commit 5f1ec1fd32252af5130dac23b5542e8e66fe0bcb upstream.
The conversion of #DE to the idtentry mechanism introduced a change in the
Ooops message which confuses tools which parse crash information in dmesg.
Remove the underscore from 'divide_error' to restore previous behaviour.
Fixes: 9d06c4027f21 ("x86/entry: Convert Divide Error to IDTENTRY")
