at the moment I see:
(keep in mind my reading skills only go so far!)

  grep -Re base_address kvm/* -n
kvm/ioapic.c:276:       return ((addr >= ioapic->base_address &&
kvm/ioapic.c:277:                (addr < ioapic->base_address + 
IOAPIC_MEM_LENGTH)));
kvm/ioapic.c:371:       ioapic->base_address = IOAPIC_DEFAULT_BASE_ADDRESS;
kvm/ioapic.h:38:        u64 base_address;

so changing base_addresss; to base_address; gets kvm_ioapic_reset to 
function correctly as well as ioapic_in_range?
(but could be wrong)
