      1 /* SH64 Linux - this code assumes the following kernel API for system calls:
      2         PC           Offset 0
      3         System Call  Offset 16 (actually, (syscall no.) | (0x1n << 16),
      4                      where n = no. of parameters.
      5         Other regs   Offset 24+
      6 
      7         On entry:    R2-7 = parameters 1-6 (as many as necessary)
      8         On return:   R9   = result.
