this makes it not a valid patch submission.

arch/x86/kernel/devicetree.c: In function ‘ioapic_xlate’:
arch/x86/kernel/devicetree.c:294:8: warning: cast from pointer to
integer of different size [-Wpointer-to-int-cast]
  idx = (__force u32) domain->host_data;
        ^
arch/x86/kernel/devicetree.c: In function ‘dt_add_ioapic_domain’:
arch/x86/kernel/devicetree.c:323:4: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]
    (void *)ioapic_num);

while the patch fixes the type cast warnings, it makes me wonder: How
did you enable it on 64bit? Both platforms (that is CE4100 and OLPC)
are 32bit only.
