Kernel cross-compilation with BUILDTIME_MCOUNT_SORT produces zeroed
mcount values if the build-host endianness does not match the ELF
file endianness.
The mcount values array is converted from ELF file
endianness to build-host endianness during initialization in
fill_relocs()/fill_addrs(). Avoid extra conversion of these values during
weak-function zeroing; otherwise, they do not match nm-parsed addresses
and all mcount values are zeroed out.

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.
