[ Upstream commit b2accfe7ca5bc9f9af28e603b79bdd5ad8df5c0b ] Commit579aee9fc5("powerpc: suppress some linker warnings in recent linker versions") enabled support to add linker option "--no-warn-rwx-segments", if the version is greater than 2.39. Similar build warning were reported recently from linker version 2.35.2. ld: warning: arch/powerpc/boot/zImage.epapr has a LOAD segment with RWX permissions ld: warning: arch/powerpc/boot/zImage.pseries has a LOAD segment with RWX permissions Fix the warning by checking for "--no-warn-rwx-segments" option support in linker to enable it, instead of checking for the version range.

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.
