      score: add generic sys_call_table · f673c032
      Arnd Bergmann 提交于
      This adds back a sys_call_table to the score architecture, which
      got lost in the conversion to the generic unistd.h file.
      It's rather worrying that the code got submitted without a
      system call table, which evidently means that it got zero
      testing.
      
      Since the system call table has a different layout from the old
      one (which was modeled after the mips-o32 one), I also try to
      fix the entry.S path to use it. In the modified calling conventions,
      all system call arguments are passed as registers r4 through r9,
      instead of r4 through r7 plus stack for the fifth and sixth argument.
      
      This matches what other architectures to when they normally pass
      arguments on the stack.
