[SCSI] aacraid driver update
changes: - set aac_cache=2 as default value to avoid performance problem (Novell bugzilla #469922) - Dell/PERC controller boot problem fixed (RedHat bugzilla #457552) - WWN flag added to fix SLES10 SP1/SP2 drive detection problems - 64-bit support changes - DECLARE_PCI_DEVICE_TABLE macro added - controller type changes Signed-off-by: Achim Leubner <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
