In fact, I notice that you had them even before, eg:

system 00:00: iomem range 0x0-0x9ffff could not be reserved
system 00:00: iomem range 0xe0000-0xfffff could not be reserved
system 00:00: iomem range 0x100000-0x7e7fffff could not be reserved

which are about exactly the same thing - e820 RAM reservations take
precedence over the PnP ones.

So the only new thing is that we claim the APIC thing to that category
too.
