asm/io_apic.h is missing in drivers/pci/quirks.c with kernel 2.5.50

Alan's patch:

+ extern int sis_apic_bug;

will work; however, adding #include <asm/io_apic.h> will cause the following on 2.5.50:

include/asm/mpspec.h:203: error: `NR_CPUS' undeclared here (not in a function)
include/asm/io_apic.h:51: error: `MAX_IO_APICS' undeclared here (not in a function)
include/asm/fixmap.h:49: error: `FIX_IO_APIC_BASE_0' used prior to declaration.

Just wanted to be sure people applied the right patch.
