Donet Tom 901083d8f5 selftests/mm: add new test cases to the migration test
Added three new test cases to the migration tests:

1. Shared anon THP migration test
This test will mmap shared anon memory, madvise it to
MADV_HUGEPAGE, then do migration entry testing. One thread
will move pages back and forth between nodes whilst other
threads try and access them.

2. Private anon hugetlb migration test
This test will mmap private anon hugetlb memory and then
do the migration entry testing.

3. Shared anon hugetlb migration test
This test will mmap shared anon hugetlb memory and then
do the migration entry testing.

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.
