This series has the purpose to extend and reorganize Highmem's documentation. This is still a work in progress, because some information should still be moved from highmem.rst to highmem.h and highmem-internal.h. Specifically I'm talking about moving the "how to" information to the relevant headers, as it as been suggested by Ira Weiny (Intel). This series is composed by four patches gathered from a previous series made of two, plus two more single patches. The subject of this cover has changed and the layout of the changes across the four patches has changed too. For this reason it is very hard to show a valid versions' log. Therefore, I decided to start over and drop versions (Maintainers of the previous patch have been told to drop them). Changes from v1 to v2: 1/4 - Fix typos (Mike Rapoport); re-write the description of @page because the original was wrong (Ira Weiny); add Ira's and Mike's tags in the commit message. 2/4 - Add Ira's and Mike's tags in the commit message. 3/4 - Rework the subject to better summarize what this patch changes; merge the section which was removed from highmem.rst with the kdocs of highmem.h (suggested by Ira Weiny); add Ira's tag in the commit message. 4/4 - Reformulate a sentence that was incomprehensible due to my own mistakes in copying and pasting the text of another paragraph (problem noted by Ira Weiny); refer to the kdocs of kmap_local_page () to show how nested mappings should be handled; fix grammar error; add Ira's tag in the commit message. Changes from v2 to v3: 1/4 - Add a deprecation notice to kunmap_atomic() for consistency with the same notice in kmap_atomic() (Sebastian Andrzej Siewior); shorten subject and extend commit message. 2/4 - No changes. 3/4 - No changes. 4/4 - Correct a technical inaccuracy about preemption disabling / re-enabling in kmap_atomic() / kunmap_atomic() (Sebastian Andrzej Siewior).
