mem=[X][G|M] is broken on ARM64 platform, there are cases that even type.cnt is 1, but total_size is not 0 because regions are merged into 1. So only check 'cnt' is not enough, total_size should be used, othersize bootargs 'mem=[X][G|B]' not work anymore.

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.
