4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felipe Balbi <felipe.balbi@xxxxxxxxxxxxxxx>
commit 04fb365c453e14ff9e8a28f1c46050d920a27a4a upstream.
%p will leak kernel pointers, so let's not expose the information on
dmesg and instead use %pK. %pK will only show the actual addresses if
explicitly enabled under /proc/sys/kernel/kptr_restrict.
