When building htmldocs on Linus' tree, there are inline emphasis warnings
on include/linux/highmem.h:
Documentation/vm/highmem:166: ./include/linux/highmem.h:154: WARNING: Inline emphasis start-string without end-string.
Documentation/vm/highmem:166: ./include/linux/highmem.h:157: WARNING: Inline emphasis start-string without end-string.
These warnings above are due to comments in code example of
kmap_atomic() inside kernel-doc comment of *kmap_local_folio() are enclosed
by double dash (--) instead of prefixed with C comment symbol (//).
Fix these warnings by indenting the code example with literal block
indentation and prefixing comments inside the example with C comment
symbol.

Changes since v1 [1]:
- Point that the code example is for kmap_atomic() (suggested by
Matthew Wilcox)
- Use C comments instead of Unix shell comments prefix (suggested by
Ira Weiny)
