The sorting of the mcount_loc section is done directly to the section for x86 and arm32 but it uses a separate array for arm64 as arm64 has the values for the mcount_loc stored in the rela sections of the vmlinux ELF file. In order to use the same code to remove weak functions, always use a separate array to do the sorting. This requires splitting up the filling of the array into one function and the placing the contents of the array back into the rela sections or into the mcount_loc section into a separate file.

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 reStructuredText 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.
