Disable stack checking on MIPS kernels. Some distribution toolchains might pass the -fstack-check option to gcc. This results in a store-doubleword instruction being emitted at the top of all functions that checks the available stack space. E.g., a80000000001d740 <per_cpu_init>: a80000000001d740: ffa0bfc0 sd zero,-16448(sp) a80000000001d744: 2405ffc9 li a1,-55 a80000000001d748: 67bdffc0 daddiu sp,sp,-64 Generally, this is undesirable, and especially on the SGI IP27 platform, it will trigger a NULL pointer dereference in '_raw_spin_lock_irq' during early init.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
