Subject: [PATCH v5 40/69] accel/whpx: Replace @dirty field by generic CPUState::vcpu_dirty field
Date: Thu,  3 Jul 2025 12:55:06 +0200	[thread overview]
Message-ID: <20250703105540.67664-41-philmd@linaro.org> (raw)
In-Reply-To: <20250703105540.67664-1-philmd@linaro.org>

No need for accel-specific @dirty field when we have
a generic one in CPUState.

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