clang sometimes decides not to inline shuffle_zone(), but it calls a __meminit function. Without the extra __meminit annotation we get this warning: WARNING: modpost: vmlinux.o(.text+0x2a86d4): Section mismatch in reference from the function shuffle_zone() to the function .meminit.text:__shuffle_zone() The function shuffle_zone() references the function __meminit __shuffle_zone(). This is often because shuffle_zone lacks a __meminit annotation or the annotation of __shuffle_zone is wrong. shuffle_free_memory() did not show the same problem in my tests, but it could happen in theory as well, so mark both as __meminit.

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.
