Subject: [PATCH] asm-generic: add dummy pgprot_noncached()
Date: Tue, 23 Jun 2009 14:41:36 +0200 [thread overview]
Message-ID: <200906231441.37158.arnd@arndb.de> (raw)
In-Reply-To: <20090622151537.2f8009f7.akpm@linux-foundation.org>
From: Paul Mundt <lethal@linux-sh.org>
Most architectures now provide a pgprot_noncached(), the
remaining ones can simply use an dummy default implementation,
except for cris and xtensa, which should override the
default appropriately.
