This\ndereferences a user pointer in kernel context, which is wrong and is\nflagged by sparse:\n\n  arch/loongarch/kernel/machine_kexec.c:84:51: sparse: incorrect type in\n  argument 2 (different address spaces) @@ expected char const * @@ got\n  char [noderef] __user *\n\nHere copy the marker-sized prefix of each segment into a small on-stack\nbuffer with copy_from_user() before comparing, and skip segments that\nfault. The subsequent copy_from_user() that stages the full command line\ninto the safe area is left unchanged.",
