There are several methods of setting and printing variables. Add a
couple frames to help clarify that before jumping into the more
complex examples.

There is a latency between when partprobe is called and when udev
actually creates the device nodes. Wait for the desired device
nodes to appear before continuing.

In case it is run on a system where PIE is not the default,
explicitly set for the binary to be built as PIE.

Remove german slides if a completely translated english version is
available. For slides that have been translated to english, but do
not contain all the information of the german slides, the german
slides are still available. But they are only available for
reference. That will not be built.

The rtex tool only demonstrates prefaultingn to avoid runtime
page faults. It makes more sense to call it pgflt.

With the device tree added, the full example no longer fits in 5 slides.
Add a 6th slide to spread things out better.

Cleanup the examples so that they show (and hide) the same things
for both examples.

There are separate files showing the full vain example. They need to
show the device tree compatibility as well.

Modern kernels will use device trees for platform devices, so
make vain do the same.
(Also fixup an unnecessary line break.)

Update slides for latest kernels. Cleanup slide contents. Add slides
about manually setting the CPU affinity.

We talk about the dynamic loader, so let's talk about how
to configure it too.

PIE binaries are now the default, so let's talk about them. Particularly
for mtrace it is important to understand.

Since PIE binaries are created by default now, it has become important
to see where the binaries are mapped in memory. LD_TRACE_PRELINKING is
the dynamic loader environment variable to see that.
$ env LD_TRACE_PRELINKING=1 ./hello | grep '=>'
