I'm curious how you've chosen this insertion point. While the first
two #include-s (just out of context) are still unsorted, the rest
currently matches our goal of alphabetical sorting (within the
sub-groups, i.e. xen/, asm/, and public/), unless there's an actual
reason to violate this pattern. Hence please don't violate this
partial sorting and move the insertion one line down.

This now exceeds 80 chars, which is the limit per line. Please wrap
accordingly.

With these taken care of
