Subject: [PATCH 03/10] omap: iommu: fix wrong condition check for SUPERSECTION
Date: Thu, 22 Oct 2009 15:11:49 -0700	[thread overview]
Message-ID: <20091022221149.27408.67112.stgit@localhost> (raw)
In-Reply-To: <20091022221013.27408.443.stgit@localhost>

From: Hiroshi DOYU <Hiroshi.DOYU@nokia.com>

A bit (2 << 0) is set both on SECTION and SUPERSECTION. To identify
SUPERSECTION correctly, other bits should be compared too.
