Subject: [PATCH 01/11] softmmu: Introduce qemu_target_page_mask/qemu_target_page_align helpers
Date: Tue, 23 May 2023 18:35:50 +0200	[thread overview]
Message-ID: <20230523163600.83391-2-philmd@linaro.org> (raw)
In-Reply-To: <20230523163600.83391-1-philmd@linaro.org>

Since TARGET_PAGE_MASK and TARGET_PAGE_ALIGN are poisoned in
target-agnostic code, introduce the qemu_target_page_mask()
and qemu_target_page_align() helpers to get these values from
target-agnostic code at runtime.
