Subject: [PATCH v3 4/4] arc: Use generic dump_stack_print_cmdline() implementation
Date:   Mon,  8 Aug 2022 15:09:17 +0200
Message-Id: <20220808130917.30760-5-deller@gmx.de>
In-Reply-To: <20220808130917.30760-1-deller@gmx.de>
References: <20220808130917.30760-1-deller@gmx.de>

Precedence: bulk

The process program name and command line is now shown in generic code
in dump_stack_print_info(), so drop the arc-specific implementation.
