The -dM argument shows the built-in macros. Cutting the #define
from the output not only make the command unnecessarily complex,
but also works against illustrating that they are macros.

fix various typos and wrong commands in slides2019-02-07T16:03:50ZHolger Denglerdengler@linutronix.de2019-02-05T11:10:44Zurn:sha1:1df58f151a324dbe97f1958fafc1471ec911c629
Fixes for:
- missing variable definition in Makefile
- wrong serial device in kernel parameters
- missing trace-cmd subcmd and wrong parameter (sched_switch is an
event, not a plugin)
- missing #include in example code
- fix copy&paste leftover

embedded-devel: fix loader env-var table to fit2018-08-31T13:05:00ZJohn Ognessjohn.ogness@linutronix.de2018-08-31T13:05:00Zurn:sha1:eb84168cfbe0e53a054a4335a8a4bd4142eef70f
The table showing the dynamic loader environment variables was
running off the edge of the slide. The main reason was because
the description column was too wide.
Reduce the description column width.

The following slide shows hello2 using DT_RPATH, so set the output
to hello2 when compiling.

remove german slides when english are available2018-02-20T14:33:14ZJohn Ognessjohn.ogness@linutronix.de2018-02-20T14:33:14Zurn:sha1:0351969fdffa9959921d8ec38b7d0d7cf095fcd0
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.

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

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 '=>'
