gcc-4.6 and older fail to inline integrator_clocksource_init, so they end up showing a harmless warning: WARNING: vmlinux.o(.text+0x4aa94c): Section mismatch in reference from the function integrator_clocksource_init() to the function .init.text:clocksource_mmio_init() The function integrator_clocksource_init() references the function __init clocksource_mmio_init(). This is often because integrator_clocksource_init lacks a __init annotation or the annotation of clocksource_mmio_init is wrong. Add the missing __init annotation that makes it build cleanly with all compilers.

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.
