Subject: [PATCH v4 04/17] hw/s390x/sclp: Use address_space_memory_is_io() in sclp_service_call()
Date: Thu,  2 Oct 2025 10:41:49 +0200	[thread overview]
Message-ID: <20251002084203.63899-5-philmd@linaro.org> (raw)
In-Reply-To: <20251002084203.63899-1-philmd@linaro.org>

When cpu_address_space_init() isn't called during vCPU creation,
its single address space is the global &address_space_memory.

As s390x boards don't call cpu_address_space_init(), cpu->as
points to &address_space_memory.

We can then replace cpu_physical_memory_is_io() by the semantically
equivalent address_space_memory_is_io() call.
