- * We used to try to deal with 64-bit BARs here, but don't any more.
- * There are many parts of this driver which would need to be modified
- * to handle a 64-bit base address, including scripts. I'm uncomfortable
- * with making those changes when I have no way of testing it, so I'm
- * just going to disable it.
- *
- * Note that some machines (eg HP rx8620 and Superdome) have bus addresses
- * below 4GB and physical addresses above 4GB. These will continue to work.
