From: Thomas Gleixner <[email protected]>
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")
