It's a case by case thing and i pointed out a few specific 
directions in the review. The IO-APIC changes should probably go on 
top of Jeremy's IO-APIC driver-ization patches. They dont 
necessarily need their own IO-APIC driver (if the resulting line 
count increase is too much), but they should not wreck Jeremy's 
IO-APIC patches.

Bootup quirks that are small modificatons to existing PC 
initialization sequences should go into x86_quirks.

Timer related changes (the APB system timer) are mostly modular 
already by virtue of half of it being a clocksource and clockevents 
driver. The remaining bit of system timer handling should be 
abstracted out as a 'struct x86_system_timer' kind of structure, 
with ->init, ->timer_irq and ->shutdown functions.

[ Although it is beyond me why ABP was done - why wasnt HPET good
  enough? HPET can do per CPU clockevents too and it's just as 
  off-chip (and hence fundamentally slow) as ABP. ]
