Subject: [PATCH AUTOSEL 5.10 22/31] sh: Fix build with CONFIG_UBSAN=y
Date: Fri, 29 Mar 2024 08:48:39 -0400 [thread overview]
Message-ID: <20240329124903.3093161-22-sashal@kernel.org> (raw)
In-Reply-To: <20240329124903.3093161-1-sashal@kernel.org>
From: Kees Cook <keescook@chromium.org>
[ Upstream commit e36b70fb8c707a0688960184380bc151390d671b ]
The early boot stub for sh had UBSan instrumentation present where it is
not supported. Disable it for this part of the build.

misc.c:(.text+0x670): undefined reference to `__ubsan_handle_shift_out_of_bounds'
