If you have SMP systems or use IOAPIC kernel option and plan on trying
out the 2.6.21-rc2 kernel you will find that it won't work so well.

 CC      arch/i386/kernel/io_apic.o
arch/i386/kernel/io_apic.c: In function 'setup_IO_APIC_irqs':
arch/i386/kernel/io_apic.c:1357: error: 'struct irq_desc' has no
member named 'affinity'
arch/i386/kernel/io_apic.c: In function 'io_apic_set_pci_routing':
arch/i386/kernel/io_apic.c:2878: error: 'struct irq_desc' has no
member named 'affinity'
make[1]: *** [arch/i386/kernel/io_apic.o] Error 1
make: *** [arch/i386/kernel] Error 2

This is a known problem to the kernel guys and there's already a patch
to fix the problem. I really don't support the kernel patches beyond
what the kernel patch developer plans to support (unless I have the
time and feel like fixing it). And since this is a release candidate
version of the kernel (and an early one at that) I don't plan on
fixing it.

So I'm just to let the users know what to expect if they try
2.6.21-rc2 and IOAPIC.
