The break instruction in RISC-V does not have an immediate value field, so the kernel cannot identify the purpose of each trap exception through the opcode. This makes the existing identification schemes in other architecture unsuitable for the RISC-V kernel. To solve this problem, this patch adds kgdb_has_hit_break(), which can help RISC-V kernel identify the KGDB trap exception.

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.
