Jianqun Xu af3b0010cd staging: android: ion: system-heap adjust orders if swiotlb limit
This patch is useful for board with totalram size larger than 4GB.

Since swiotlb has memory size limitation, this will calculate the
maximum size locally, as a workaround to fix the orders[0].

With this patch:
[    3.921612] orders[0] = 6
[    3.921647] orders[1] = 4
[    3.921715] orders[2] = 0

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
