47 * Copy module-related data into the load area, where it can be
48 * used as a directory for loaded modules.
49 *
50 * Module data is presented in a self-describing format. Each datum
51 * is preceded by a 32-bit identifier and a 32-bit size field.
52 *
53 * Currently, the following data are saved:
54 *
55 * MOD_NAME (variable) module name (string)
56 * MOD_TYPE (variable) module type (string)
57 * MOD_ARGS (variable) module parameters (string)
58 * MOD_ADDR sizeof(vm_offset_t) module load address
59 * MOD_SIZE sizeof(size_t) module size
60 * MOD_METADATA (variable) type-specific metadata
48 * We have 4 byte alignment for 32-bit targets. This code is compiled as 32-bit
49 * code...
