- * The COMPAT_SYSCALL_WRAP macro generates system call wrappers to be used by
- * compat tasks. These wrappers will only be used for system calls where only
- * the system call arguments need sign or zero extension or zeroing of the upper
- * 33 bits of pointers.
- * Note: since the wrapper function will afterwards call a system call which
- * again performs zero and sign extension for all system call arguments with
- * a size of less than eight bytes, these compat wrappers only touch those
- * system call arguments with a size of eight bytes ((unsigned) long and
- * pointers). Zero and sign extension for e.g. int parameters will be done by
- * the regular system call wrappers.
