Define a function to check if a CMA area is valid, which means: do its ranges not cross any zone boundaries. Store the result in the newly created flags for each CMA area, so that multiple calls are dealt with. This allows for checking the validity of a CMA area early, which is needed later in order to be able to allocate hugetlb bootmem pages from it with pre-HVO.

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.
