gcc-4.6 causes a harmless warning about the init function: WARNING: vmlinux.o(.text+0xed62c2): Section mismatch in reference from the function init_unisys() to the function .init.text:visorutil_spar_detect() The function init_unisys() references the function __init visorutil_spar_detect(). This is often because init_unisys lacks a __init annotation or the annotation of visorutil_spar_detect is wrong. It appears that newer versions inline visorutil_spar_detect(), end up with an empty __init section. This marks the module entry points as __init and __exit respectively, which avoids the warning and slightly reduces the runtime code size.

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.
