Subject: [PATCH] arch/x86: get rid of KERN_CONT in show_fault_oops()
Date:   Wed, 20 Jun 2018 14:55:40 +0200
Message-Id: <20180620125540.228766-1-dvyukov@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Dmitry Vyukov <dvyukov@google.com>

KERN_CONT leads to split lines in kernel output
and complicates useful changes to printk like
printing context before each line.

Only acceptable use of continuations is basically
boot-time testing.

Get rid of it.
