The operation to set the IOAPIC ID in phys_id_present_map is as convoluted as it can be. 1) Allocate a bitmap of 32byte size on the stack 2) Zero the bitmap and set the IOAPIC ID bit 3) Or the temporary bitmap over phys_id_present_map The same functionality can be achieved by setting the IOAPIC ID bit directly in the phys_id_present_map.
