Subject: [PATCH v3 06/20] exec: Tidy TARGET_PAGE_ALIGN
Date: Sat, 21 Sep 2019 20:54:44 -0700 [thread overview]
Message-ID: <20190922035458.14879-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20190922035458.14879-1-richard.henderson@linaro.org>
Use TARGET_PAGE_MASK twice instead of TARGET_PAGE_SIZE once.
This is functionally identical, but will help a following patch.
