96 * Copy module-related data into the load area, where it can be

99 * Module data is presented in a self-describing format. Each datum
100 * is preceded by a 32-bit identifier and a 32-bit size field.
101 *
102 * Currently, the following data are saved:
103 *
104 * MOD_NAME (variable) module name (string)
105 * MOD_TYPE (variable) module type (string)
106 * MOD_ARGS (variable) module parameters (string)
107 * MOD_ADDR sizeof(vm_offset_t) module load address
108 * MOD_SIZE sizeof(size_t) module size
109 * MOD_METADATA (variable) type-specific metadata
