When using the automarkup extension with:

This happens because not all references will belong to a single
PDF/LaTeX document.
Better to just ignore those than breaking Sphinx build.

The handling of dashes in particular results in confusing
documentation in a number of instances, since "--" becomes an
en-dash. This disables SmartyPants wholesale, losing smart quotes
along with smart dashes.
With Sphinx 1.6 we could fine-tune the conversion, using the new
smartquotes and smartquotes_action settings.

The UP.rst file calls for locks acquired within RCU callback functions
to use _irq variants (spin_lock_irqsave() or similar), which does work,
but can be overkill. This commit therefore instead calls for _bh variants
(spin_lock_bh() or similar), while noting that _irq does work.
