Guo Ren f4625ee0e4 csky: Use in_syscall & forget_syscall instead of r11_sig ... We could use regs->sr 16-24 bits to detect syscall: VEC_TRAP0 and r11_sig is no necessary for current implementation. In this patch, we implement the in_syscall and forget_syscall which are inspired from arm & nds32, but csky pt_regs has no syscall_num element and we just set zero to regs->sr's vector-bits-field instead. For ret_from_fork, current task was forked from parent which is in syscall progress and its regs->sr has been already setted with VEC_TRAP0.
