[Bug 333739] Sycalls are very slow

Using "auditctl -e 0" improved speed a bit. Running my benchmark (20 million
getuid() calls) in runlevel 1 I got these times:
default kernel, audit on: 8.312 seconds
default kernel, audit off: 6.443 seconds
my own kernel, no audit support: 2.998 seconds
Kubuntu kernel, no audit support: 3.018 seconds (runlevel 5)
Which means there is something else that is taking a lot of time, something
that does not get switched off by the auditctl command. As Tony said, Ubuntu
has CONFIG_AUDITSYSCALL disabled.
