- Based on feed back from @mgeisler, update the kbd tag guidance in
GEMINI.md to require wrapping each key in its own tag (e.g.,
`<kbd>Ctrl</kbd> + <kbd>S</kbd>`).
- Apply this new convention to existing content in the `src` directory
to ensure consistency.
The speaker notes should prompt a deeper discussion around the
exercise by calling out the non-obvious integer overflow pitfall and
encourage instructors to explore alternative implementations with
students, moving beyond a surface-level recursive solution.
Following the style guide, these notes provide additional context for
instructors and self-learners. The notes focus on practical tips for
running the course and highlighting key information for students.
This file was inconsistent with the other files in our course.
I don’t actually know if both work, but if not, we should consider
erroring out to ensure consistency going forward.
I asked Gemini to review the English for inconsistencies and grammar
mistakes. This is the result and I hope it's useful!
As a non-native speaker, it is hard for me to evaluate the finer
details, so let me know if you would like to see changes (or even
better: make them directly in the PR with the suggestion function).

This section covers both references and slices, but the exercise focuses
on references. This speaker note briefly discusses the option to use
slices instead, and a cost of doing so.

<h2>Breaking changes</h2>
<ul>
<li><code>zerocopy</code> feature has been removed.

<li><code>IdMap::activate</code> now returns the previous TTBR value
rather than storing it, and

parameter. <code>IdMap::mark_active</code> no longer
takes a previous TTBR value parameter. The same applies to the
equivalent methods on <code>LinearMap</code>.</li>
<li>Renamed <code>Mapping::activate_raw</code> to <code>activate</code>,
and added previous TTBR value parameter to
<code>Mapping::deactivate</code>.</li>
<li>A page table may be activated multiple times (e.g. on multiple
cores) and will keep track of how
many times it has been activated. It will only be considered inactive
once it has been deactivated
the same number of times.</li>
<li><code>MapError::PteUpdateFault</code> now contains a
<code>usize</code> rather than a <code>Descriptor</code>.</li>
<li><code>Descriptor</code> no longer implements <code>Copy</code>,
