- * Name: elf_addrenv_alloc
- *
- * Description:
- *   Allocate memory for the ELF image (elfalloc). If CONFIG_ADDRENV=n,
- *   elfalloc will be allocated using kzalloc().  If CONFIG_ADDRENV-y, then
- *   elfalloc will be allocated using up_addrenv_create().  In either case,
- *   there will be a unique instance of elfalloc (and stack) for each
- *   instance of a process.
- *
- * Input Parameters:
- *   loadinfo - Load state information
- *   envsize - The size (in bytes) of the address environment needed for the
- *     ELF image.
- *
- * Returned Value:
- *   Zero (OK) on success; a negated errno value on failure.
