Subject: [PATCH 4/4] target/ppc: Prohibit target specific KVM prototypes on user emulation
Date: Tue, 12 Sep 2023 13:30:26 +0200 [thread overview]
Message-ID: <20230912113027.63941-5-philmd@linaro.org> (raw)
In-Reply-To: <20230912113027.63941-1-philmd@linaro.org>
None of these target-specific prototypes should be used
by user emulation. Remove their declaration there, so we
get a compile failure if ever used (instead of having to
deal with linker and its possible optimizations, such
dead code removal).
