By default sparse uses the characteristics of the build machine to infer things like the wordsize. This is fine when doing native builds but for ARM it's, I suspect, very rarely the case and if the build are done on a 64bit machine we get a bunch of warnings like: 'cast truncates bits from constant value (... becomes ...)' Fix this by adding the -m32 flags for sparse.

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.
