this patch is responsible for massive performance degradation for those
who used only CONFIG_SECURITY_APPARMOR.
And the numbers are, take the following test for instance:
dd if=/dev/zero of=/dev/null count=2M
ARM64: 500MB/s -> 350MB/s
ARM: 400MB/s -> 300MB/s
(with some particular CPU frequencies).
Should we revert this patch?
