Subject: [RFC PATCH-for-10.1 3/4] tcg: Have tcg_req_mo() use runtime TCGContext::guest_mo
Date: Fri, 21 Mar 2025 13:57:36 +0100	[thread overview]
Message-ID: <20250321125737.72839-4-philmd@linaro.org> (raw)
In-Reply-To: <20250321125737.72839-1-philmd@linaro.org>

In order to use TCG with multiple targets, replace the
compile time use of TCG_GUEST_DEFAULT_MO by a runtime
access to tcg_ctx->guest_mo.
