      [POWERPC] Make syscall restart code more common · 22e38f29
      Benjamin Herrenschmidt 提交于
      This patch moves the code in signal_32.c and signal_64.c for handling
      syscall restart into a common signal.c file and converge around a single
      implementation that is based on the 32 bits one, using trap, ccr
      and r3 rather than the special "result" field for deciding what to do.
      
      The "result" field is now pretty much deprecated. We still set it for
      the sake of whatever might rely on it in userland but we no longer use
      it's content.
      
      This, along with a previous patch that enables ptracers to write to
      "trap" and "orig_r3" should allow gdb to properly handle syscall
      restarting.
