An SELinux message that contains "avc: granted {something}" is just a
notification, not an error or denial (a denial would say "denied").  In
this case, memory was mmap'ed with both write and execute permission and
SELinux is set up to log it.  See:

http://people.redhat.com/drepper/selinux-mem.html

This type of memory usage is, FWIW, common in the X/graphics area.  So
the "granted" messages may appear from time to time; there's no need to
be alarmed by them.
