Commit34dc2efb39("memblock: fix section mismatch warning") marked memblock_bottom_up() and memblock_set_bottom_up() as __init, but they could be referenced from non-init functions like memblock_find_in_range_node() on architectures that enable CONFIG_ARCH_KEEP_MEMBLOCK. For such builds kernel test robot reports: WARNING: modpost: vmlinux.o(.text+0x74fea4): Section mismatch in reference from the function memblock_find_in_range_node() to the function .init.text:memblock_bottom_up() The function memblock_find_in_range_node() references the function __init memblock_bottom_up(). This is often because memblock_find_in_range_node lacks a __init annotation or the annotation of memblock_bottom_up is wrong. Replace __init annotations with __init_memblock annotations so that the appropriate section will be selected depending on CONFIG_ARCH_KEEP_MEMBLOCK.

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.
