This fixes a regression added by 238468b2 ("[SPARC64]: Use trap type stored in pt_regs to handle syscall restart.") Because we now encode the "returning from syscall" status in the pt_regs area, we have to be mindful to zap it out in the child of a fork. During a parallel kernel build I saw an accidental -EINTR return from vfork() in 'make' because of this bug. Signed-off-by: NDavid S. Miller <davem@davemloft.net>
