As part of "zsmalloc: replace kmap_atomic with kmap_local_page" [1] we replaced kmap/kunmap_atomic() with kmap_local_page()/kunmap_local(). But later it was found that some of the code could be replaced with already available apis in highmem.h, such as memcpy_from_page()/memcpy_to_page(). Also, update the comments with correct api naming.

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 reStructuredText 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.
