Date: Wed, 2 Dec 2009 17:51:46 -0800 Message-ID: <1259805106-23636-1-git-send-email-pbathija@amcc.com> Return-path: Received: from sdcmail01.amcc.com ([198.137.200.72]:2490 "EHLO sdcmail01.amcc.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752562AbZLCBvk (ORCPT ); Wed, 2 Dec 2009 20:51:40 -0500 Sender: linux-scsi-owner@vger.kernel.org List-Id: linux-scsi@vger.kernel.org To: linux-scsi@vger.kernel.org Cc: linuxppc-dev@ozlabs.org, jwboyer@linux.vnet.ibm.com, benh@kernel.crashing.org, Eric.Moore@lsi.com, Pravin Bathija Powerpc 44x uses 36 bit real address while the real address defined in MPT Fusion driver is of type 32 bit. This causes ioremap to fail and driver fails to initialize. This fix changes the data types representing the real address from unsigned long 32-bit types to resource_size_t which is 64-bit. The driver has been tested, the disks get discovered correctly and can do IO.
