Locking API testsuite output mangled

The "Locking API testsuite" output during bootup (with
CONFIG_DEBUG_LOCKING_API_SELFTESTS=y) on this PowerPC system looks
mangled, possibly related to the recent printk changes (4bcc595ccd80,
"printk: reinstate KERN_CONT for printing continuation lines"). Before
(e.g. with v4.6) it looked like this:
http://nerdbynature.de/bits/4.6.0-rc7/dmesg.txt
See below for the current output.
