Subject: [PATCH] powerpc/boot: Mark exit() and ps3_exit() as __noreturn
Date: Fri,  7 Aug 2026 17:23:53 +0200	[thread overview]
Message-ID: <20260807152353.306889-2-thorsten.blum@linux.dev> (raw)

Since neither exit() nor ps3_exit() return, annotate both functions with
the __noreturn attribute to improve compiler optimizations.
