Subject: [PATCH 03/33] linux-user: Remove qemu_host_page_{size, mask} in probe_guest_base
Date: Fri, 18 Aug 2023 10:11:57 -0700 [thread overview]
Message-ID: <20230818171227.141728-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20230818171227.141728-1-richard.henderson@linaro.org>
The host SHMLBA is by definition a multiple of the host page size.
Thus the remaining component of qemu_host_page_size is the
target page size.
