In some configurations, the exact placement of the rmtfs shared memory region isn't so strict. The DeviceTree author can then choose to use the "size" property and rely on the OS for placement (in combination with "alloc-ranges", if desired). But on some platforms the rmtfs memory region may not be allocated adjacent to regions allocated by other clients. Add support for discarding the first and last 4k block in the region, if qcom,use-guard-pages is specified in DeviceTree.

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.
