 6.1.0    - Fix for 32-bit SADUMP dumpfiles to correctly check whether a
            requested physical address is within the 0-640K backup region.
            Without the patch, requested physical addresses that are larger 
            than 32-bits are truncated to 32-bit values, leading to unexpected
            results.

          - Fix for Linux 3.0 and later kernels that have been configured with
            CONFIG_SLAB and without CONFIG_NODES_SHIFT.  Without the patch, the
            warning messages "crash: nr_node_ids: symbol does not exist" and
            "crash: unable to initialize kmem slab cache subsystem" are displayed
            during initialization, and the "kmem -[sS]" options fail with the
            message "kmem: kmem cache slab subsystem not available".
