Subject: [PATCH 16/24] exec: Move GUEST_ADDR_MAX definition to 'cpu_ldst.h'
Date: Thu, 18 Apr 2024 21:25:15 +0200	[thread overview]
Message-ID: <20240418192525.97451-17-philmd@linaro.org> (raw)
In-Reply-To: <20240418192525.97451-1-philmd@linaro.org>

GUEST_ADDR_MAX is only used in accel/tcg/user-exec.c
and "exec/cpu_ldst.h". Move it from "exec/cpu-all.h"
to "exec/cpu_ldst.h" so we can avoid including
"exec/cpu-all.h" in accel/tcg/user-exec.c.

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
