sparc64: Clean up handling of pt_regs trap type encoding.
If we use this from more than one place, it's better to have helpers instead of twiddling magic constants all over. Add pt_regs_trap_type(), pt_regs_clear_trap_type(), and pt_regs_is_syscall(). Use them in do_signal(). Signed-off-by: David S. Miller <davem@davemloft.net>
