This was tested on kernel.org 'next-20191128' as Rawhide kernels
don't yet support the new perf_event hooks.

Note that the default .config enables the following that have been added
to defconfig:
CONFIG_HAVE_PERF_EVENTS=y
CONFIG_PERF_EVENTS=y
CONFIG_TRACEPOINTS=y

To allow testing, the following steps are required to update Fedora
policy:

1) Using the diff below, add the perf_event class and its
   permissions to:
/usr/share/selinux/devel/include/support/all_perms.spt



2) Create a cil module 'test_perf.cil' that defines the class:

(class perf_event (open cpu kernel tracepoint read write))
(classorder (unordered perf_event))

Then insert into policy:
semodule -i test_perf.cil
