Subject: [PATCH v8 08/10] kgdb: Provide a stub kgdb_nmicallback() if !CONFIG_KGDB
Date:   Wed, 19 Apr 2023 15:56:02 -0700
Message-ID: <20230419155341.v8.8.Ia3aeac89bb6751b682237e76e5ba594318e4b1aa@changeid>
In-Reply-To: <20230419225604.21204-1-dianders@chromium.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

To save architectures from needing to wrap the call in #ifdefs, add a
stub no-op version of kgdb_nmicallback(), which returns 1 if it didn't
handle anything.
