Roman Gushchin 8eb92ed254 mm: swap_cgroup: allocate swap_cgroup map using vcalloc()
Currently swap_cgroup's map is constructed as a vmalloc()'s-based array of
pointers to individual struct pages.  This brings an unnecessary
complexity into the code.

This patch turns the swap_cgroup's map into a single space
allocated by vcalloc().

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.
