Subject: [PATCH v2 1/7] cpu: use ROUND_UP() to define xxx_PAGE_ALIGN
Date: Wed, 23 Oct 2019 11:44:59 -0400	[thread overview]
Message-ID: <20191023154505.30521-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191023154505.30521-1-richard.henderson@linaro.org>

From: Wei Yang <richardw.yang@linux.intel.com>

Use ROUND_UP() to define, which is a little bit easy to read.
