From e46b63b37c3296f0aca92d8b62bbf130f2bec7dd Mon Sep 17 00:00:00 2001 From: Pravin Bathija Date: Wed, 2 Dec 2009 17:51:46 -0800 Subject: [PATCH] [SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources. 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.
