Subject: [PATCH 17/22] target/ppc: Get cpu first addr space with cpu_get_address_space()
Date: Wed,  1 Oct 2025 17:05:22 +0200	[thread overview]
Message-ID: <20251001150529.14122-18-philmd@linaro.org> (raw)
In-Reply-To: <20251001150529.14122-1-philmd@linaro.org>

In order to remove the convenient CPUState::as field, access
the vcpu first address space using the cpu_get_address_space()
helper.
