Subject: [PATCH v2 11/29] tcg: Create tcg_init
Date: Sun, 14 Mar 2021 15:27:06 -0600 [thread overview]
Message-ID: <20210314212724.1917075-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210314212724.1917075-1-richard.henderson@linaro.org>
Perform both tcg_context_init and tcg_region_init.
Do not leave this split to the caller.
