Use the array for lapic_id directly to avoid the unnecessary pointer arithmetic. With current implementation, lapic_id_base is always a byte array with CPU_PAGE_SIZE elements What this patch does: - replace 'uint8_t *lapic_id_base' with 'uint8_t lapic_id_array[CPU_PAGE_SIZE]' to make the boundary explicit - add a range check to ensure that there is no overflow v2 -> v3: * update the array size of lapic_id_array per discussion with Fengwei v1 -> v2: * remove the unnecessary range check in parse_madt in cpu.c Signed-off-by: Shiqing Gao <shiqing.gao@intel.com> Reviewed-by: Junjie Mao <junjie.mao@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
