Sebastian Andrzej Siewior 3879a6f329 x86: dtb: Add early parsing of IO_APIC ... APIC and IO_APIC have to be added to the system early because native_init_IRQ() requires it. In order to obtain the address of the ioapic the device tree has to be unflattened so of_address_to_resource() works. The device tree is relocated to ensure it is always covered by the kernel mapping. That way the boot loader does not have to make any assumptions about kernel's memory layout.
