Subject: [PATCH v3 1/7] ARM: Align machine_desc.phys_io to a 1MB section
Date: Mon, 21 Jun 2010 10:13:31 +0100 [thread overview]
Message-ID: <20100621091331.22752.73990.stgit@e102109-lin.cambridge.arm.com> (raw)
In-Reply-To: <20100621090801.22752.21039.stgit@e102109-lin.cambridge.arm.com>
Platforms like RealView don't pass a section-aligned pointer via the
machine_desc structure. This patch aligns the pointer in the
__create_page_tables function. Reported by Tony Thompson.
