kmap_local_page() should always be preferred in place of kmap() and kmap_atomic(). "Only use when really necessary." is not consistent with the Documentation/mm/highmem.rst and these kdocs it embeds. Therefore, delete the above-mentioned sentence from kdocs. Link: https://lkml.kernel.org/r/20220728154844.10874-7-fmdefrancesco@gmail.com Signed-off-by: Fabio M.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
