On some Qualcomm platforms the firwmare, or hardware, does not gracefully handle memory protection of the rmtfs memory region when placed adjacent to other protected region. Some DeviceTree authors have worked around this issue by explicitly reserving the space around the region, but this prevents such author to use rely on the OS to place the region, through the use of "size" (instead of a fixed location). Introduce a flag to indicate that guard pages need be carved at the beginning and end of the memory region. The user shall account for the two pages in the defined size.

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.
