Revision fe4e09e701213213cf2024e2979ea227c2e36c60 authored by Matt Redfearn on 19 October 2016, 13:33:21 UTC, committed by Ralf Baechle on 03 November 2016, 23:58:57 UTC
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.
