[ Upstream commit 375561bd6195a31bf4c109732bd538cb97a941f4 ] Fix the following Sparse warnings that got noticed when the PPC-dev patchwork was checking another patch (see the link below): init/main.c:862:1: warning: symbol 'randomize_kstack_offset' was not declared. Should it be static? init/main.c:864:1: warning: symbol 'kstack_offset' was not declared. Should it be static? Which in fact are triggered on all architectures that have HAVE_ARCH_RANDOMIZE_KSTACK_OFFSET support (for instances x86, arm64 etc).

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.
