This reverts commitad2c814441. The function node_to_mem_node() was introduced by that commit for use in SLUB on systems with memoryless nodes, but it turned out to be unreliable on some architectures/configurations and a simpler solution exists than fixing it up. Thus commit0715e6c516("mm, slub: prevent kmalloc_node crashes and memory leaks") removed the only user of node_to_mem_node() and we can revert the commit that introduced the function.

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.
