/* This file should define the function-like macro of no arguments
ARCH_FORK to an INLINE_SYSCALL invocation of the clone-like system
call, passing the CLONE_CHILD_SETTID and CLONE_CHILD_CLEARTID flags
and &THREAD_SELF->tid as the TID address.
Machines that lack an arch-fork.h header file will hit an #error in
fork.c; this stub file doesn't contain an #error itself mainly for
the transition period of migrating old machine-specific fork.c files
to machine-specific arch-fork.h instead. */
