Is there a reason why the 8259 mask/unmask operations are separated from
io-apic mask/unmask operations.

Can we keep it together so that it will be easy to read and understand
that we first do the interrupt subsystem mask, try enabling IR and
x2apic and  unmask the interrupt subsystem.

Otherwise I am ok with this change.

thanks,
suresh
