![]() While removing allnoconfig_y from Kconfig, ARCH=mips allnoconfig builds started failing with the error: WARNING: modpost: vmlinux.o(.text+0x9c70): Section mismatch in reference from the function reserve_exception_space() to the function .meminit.text:memblock_reserve() The function reserve_exception_space() references the function __meminit memblock_reserve(). This is often because reserve_exception_space lacks a __meminit annotation or the annotation of memblock_reserve is wrong. ERROR: modpost: Section mismatches detected. Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them. allnoconfig disables DEBUG_KERNEL and thus ARCH_KEEP_MEMBLOCK, which changes __init_memblock to be equivalent to __meminit triggering the above error.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
