Crud, I had a copy-paste error.  There are also printk format warnings
in io_apic_64.c:

linux-next-20080819/arch/x86/kernel/io_apic_64.c:1284: warning: format '%08x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'
linux-next-20080819/arch/x86/kernel/io_apic_64.c:1285: warning: format '%08x' expects type 'unsigned int', but argument 2 has type 'long unsigned int
