Modified files:
sys/kern : kern_fork.c
Log message:
Make a child execute fork_return() only if PTRACE_FORK has been specified.
fork_return() does an additional check to send a SIGTRAP (for a debugger)
but this signal might overwrite the SIGSTOP generated by the parent doing
a PT_ATTACH before the child has a change to execute any instruction.
Prevent a race visible only on SP system with regress/sys/kern/ptrace2.
