For tiny systems that have used SLOB until now, SLUB might be impractical due to its higher memory usage. To help with that, introduce an option CONFIG_SLUB_TINY that modifies SLUB to use less memory. This is done by sacrificing scalability, security and debugging features, therefore not recommended for any system with more than 16MB RAM. This commit introduces the option and uses it to set other related options in a way that reduces memory usage.

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.
