Subject: [PATCH v2 08/13] sh: fault: Modernize printing of kernel messages
Date:   Sun, 16 Feb 2020 10:18:38 +0200
Message-Id: <20200216081843.28670-9-rppt@kernel.org>
In-Reply-To: <20200216081843.28670-1-rppt@kernel.org>

Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Geert Uytterhoeven <geert+renesas@glider.be>

  - Convert from printk() to pr_*(),
  - Add missing continuations,
  - Use "%llx" to format u64,
  - Join multiple prints in show_fault_oops() into a single print.
