 * 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.
