[Ricardo Ribalda Delgado]

arch/x86/kernel/devicetree.c: In function âioapic_xlateâ:
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 âdt_add_ioapic_domainâ:
arch/x86/kernel/devicetree.c:323:4: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    (void *)ioapic_num);
