Subject: [for-next][PATCH 01/25] objtool: Add vpanic() to the noreturn list
Date: Fri, 25 Jul 2025 16:33:58 -0400	[thread overview]
Message-ID: <20250725203424.107916458@kernel.org> (raw)
In-Reply-To: 20250725203357.087558746@kernel.org

From: Nam Cao <namcao@linutronix.de>

vpanic() does not return. However, objtool doesn't know this and gets
confused:
kernel/trace/rv/reactor_panic.o: warning: objtool: rv_panic_reaction(): unexpected end of section .text

Add vpanic() to the list of noreturn functions.
