The code to implement THP migrations already exists, and the code for CMA to clear out a region of memory already exists. Only a few small tweaks are needed to allow CMA to move THP memory when attempting an allocation from alloc_contig_range. With these changes, migrating THPs from a CMA area works when allocating a 1GB hugepage from CMA memory.

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.
