Subject: [PATCH 03/20] mips: add missing declarations for trap handlers
Date: Mon, 4 Dec 2023 12:56:53 +0100 [thread overview]
Message-ID: <20231204115710.2247097-4-arnd@kernel.org> (raw)
In-Reply-To: <20231204115710.2247097-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
These exception handlers are all called from assembly code, so they don't
normally need a declaration, but without one we now get warnings:
