1096 * the process's state.  The note name is "NetBSD-CORE" for
1097 * information that is global to the process, and "NetBSD-CORE@nn",
1098 * where "nn" is the lwpid of the LWP that the information belongs
1099 * to (such as register state).
1100 *
1101 * We use the following note identifiers:
1102 *
1103 *      ELF_NOTE_NETBSD_CORE_PROCINFO
1104 *              Note is a "netbsd_elfcore_procinfo" structure.

1106 *              Note is an array of AuxInfo structures.
1107 *
1108 * We also use ptrace(2) request numbers (the ones that exist in
1109 * machine-dependent space) to identify register info notes.  The
1110 * info in such notes is in the same format that ptrace(2) would
1111 * export that information.
1112 *
