The current scheme is to only push bug fixes and maybe new drivers to
the stable-* branch, excluding any change that would prevent
applications based on earlier releases from the same branch from running
on later ones.
e.g. for the 3.0.x series, an app built for 3.0.2 must build with no
change on 3.0.6. Regarding ABI stability, the same app must run over a
3.0.6 kernel support without rebuilding.
The next branch is where new core features, new CPU architecture ports,
or large scale changes may go, breaking the ABI between applications and
the Cobalt core if need be.

Patches may be easier for reviewing changes.

Start small, then progress as you get your feet wet. There is no such
thing as a minor contribution, there is no shame in making mistakes. A
contributor who submits a perfectible one-liner surely advances the
project further than any smart lurker.

the syntax is:
link:<public-name-of-page>[text displayed as the active link]
The page name is relative to the site root; for instance, a link
displayed as "foo" in the text, pointing at the "start here" page, would
be expressed as:
link:start-here[foo]
You can figure out page names either by looking at the last part of an
existing page URL in your browser, or at the title line (first one,
underlined by '===') from each .adoc file. In the latter case, the title
string is converted to all lowercase, replacing non-alphanumeric chars
by a dash.

Depends on the purpose as mentioned earlier.

Generally speaking, the kernel part of Xenomai - aka Cobalt core - aims
at following the standard kernel coding style (i.e.
Documentation/CodingStyle).
