Subject: [PATCH 19/27] accel/tcg: Remove cpu_atomic_{ld,st}o_*_mmu
Date: Sat, 20 May 2023 09:26:26 -0700 [thread overview]
Message-ID: <20230520162634.3991009-20-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230520162634.3991009-1-richard.henderson@linaro.org>
Atomic load/store of 128-byte quantities is now handled
by cpu_{ld,st}16_mmu.
