Public bug reported:
I noticed this because mysql failed to start after I rebooted my
machine. I initially thought this was because of a change in mysql:
[ 1323.162491] audit: type=1400 audit(1488154060.141:39): apparmor="DENIED"
operation="open" profile="/usr/sbin/mysqld" name="/sys/devices/system/node/"

comm="mysqld" requested_mask="r" denied_mask="r" fsuid=107 ouid=107
I added those two files in usr.sbin.mysqld, the error messages went away
but mysql still doesn't start. I See other messages as well, here's the
entire log:

I wasn't sure if I should log the bug against apparmor or mysql, but
since I see multiple problems here I logged it against apparmor.
