Subject: [PATCH v3 60/88] target/hppa: Adjust vmstate_env for pa2.0 tlb
Date: Wed, 1 Nov 2023 18:29:48 -0700 [thread overview]
Message-ID: <20231102013016.369010-61-richard.henderson@linaro.org> (raw)
In-Reply-To: <20231102013016.369010-1-richard.henderson@linaro.org>
Split out the tlb to a subsection so that it can be separately
versioned -- the format is only partially following the architecture
and is partially guided by the qemu implementation.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
