Geert reported commitae6b289a37("kbuild: Set KBUILD_CFLAGS before incl. arch Makefile") broke cross-compilation using a cross-compiler that supports less compiler options than the host compiler. For example, cc1: error: unrecognized command line option "-Wno-unused-but-set-variable" This problem happens on architectures that setup CROSS_COMPILE in their arch/*/Makefile. Move the cc-option and cc-disable-warning back to the original position, but keep the Clang target options untouched.

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.
