commit afb2a4fb84555ef9e61061f6ea63ed7087b295d5 upstream. The cflags for the RISC-V efistub were missing -mno-relax, thus were under the risk that the compiler could use GP-relative addressing. That happened for _edata with binutils-2.41 and kernel 6.1, causing the relocation to fail due to an invalid kernel_size in handle_kernel_image. It was not yet observed with newer versions, but that may just be luck.

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.
