This should instead be declared as an unsigned long, as memory addresses cannot really be negative. This allows ioremap() to correctly remap the address in a >32 bit context. See additional bug details in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1717259 Impact: Adaptec ethernet hardware utilizing the starfire driver fails to initialize with 4.x series kernels and 3.x pae kernels. Steps to reproduce: Attempt to load current starfire module on a system with this hardware installed: modprobe -v starfire Actual Results: Output from dmesg when loading current starfire module on system with this hardware equipped: [ 1109.362648] ioremap: invalid physical address fffffffffe480000 [ 1109.362657] starfire 0000:08:04.0: cannot Remap 0x80000 @ 0xfe480000, aborting Proposed patch: Modify line 653 to declare ioaddr as an unsigned long int. 653 unsigned long ioaddr; Expected Results: Output from dmesg when loading modified starfire module on system with this hardware equipped: [ 1237.456827] eth2: Adaptec Starfire 6915 at f8a00000, 00:00:d1:ef:f6:d1, IRQ 25.
