Message-Id: <20090520182505.EA2386EB@kernel>
Date:	Wed, 20 May 2009 11:25:05 -0700
From:	Dave Hansen <dave@...ux.vnet.ibm.com>

Cc:	linux-kernel@...r.kernel.org, Dave Hansen <dave@...ux.vnet.ibm.com>
Subject: [RFC v2][PATCH 13/35] parisc: create ptemap.h


Note that parisc already had two pte_unmap{_unmap}()
#defines. This removes the dup in addition to moving
them.
