This has been in the ia64 patch for ages.  It
	- removes two unused variables,
	- fixes a printk format string, and
	- removes a virt_to_bus() that doesn't work on some
	  ia64 boxes

The virt_to_bus() usage was removed from 2.6 in the
upgrade to version 2.03 of the driver:
    http://linux.bkbits.net:8080/linux-2.5/cset@1.971.136.1?nav=index.html|src/.|src/drivers|src/drivers/scsi|related/drivers/scsi/megaraid.c

Please apply to 2.4.
