In preparation for the next patch, move the kmalloc_slab() function to the header, as it will have callers from two files, and make it inline. To avoid unnecessary bloat, remove all size checks/warnings from kmalloc_slab() as they just duplicate those in callers, especially after recent changes to kmalloc_size_roundup(). We just need to adjust handling of zero size in __do_kmalloc_node(). Also we can stop handling NULL result from kmalloc_slab() there as that now cannot happen (unless called too early during boot). The size_index array becomes visible so rename it to a more specific kmalloc_size_index.

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.
