From fe4e09e701213213cf2024e2979ea227c2e36c60 Mon Sep 17 00:00:00 2001 From: Matt Redfearn Date: Wed, 19 Oct 2016 14:33:21 +0100 Subject: [PATCH] MIPS: traps: Fix output of show_stacktrace Since commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing continuation lines") the output from show_stacktrace on MIPS has been pretty unreadable due to the lack of KERN_CONT markers. Use pr_cont to provide the appropriate markers & restore the expected output. Also start a new line with printk such that the presence of timing information does not interfere with output.
