[1]: Commitb6c7a324df("MIPS: Fix get_frame_info() handling of microMIPS function size") [2]: Commit2b424cfc69("MIPS: Remove function size check in get_frame_info()") First patch added a constant to check the number of iterations against. Second patch fixed the situation that info->func_size is zero. However, func_size member became useless after the second commit. Without ip_end, the get frame_size operation may be out of range although KALLSYMS enabled. Thus, check func_size first. Then make ip_end be the sum of ip and a constant (512) if func_size is equal to 0. Otherwise make ip_end be the sum of ip and func_size.

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.
