Subject: [PATCH] add OEM SAL call functions
Message-Id: <4126171C.mailx2731118NN@aqua.americas.sgi.com>
List-Id: <linux-ia64.vger.kernel.org>
MIME-Version: 1.0

To: linux-ia64@vger.kernel.org

Add wrapper functions for SAL_CALL(), SAL_CALL_NOLOCK(), and
SAL_CALL_REENTRANT() that allow OEM written modules to make calls
to OEM SAL functions.
