 Linux system calls take arguments as follows :

   i386    m68k    ppc
   %eax    %d0     r0      System call number
   %ebx    %d1     r3      first argument
   %ecx    %d2     r4      second argument
   %edx    %d3     r5      third argumens
   %esi    %d3     r6      fourth argument
   %edi    %d4     r7      fifth argument

  That is why we define a special type, with only these arguments
  To make it processor independent, we don't give any system dependent
  names, but the rather abstract reg1,reg2 etc;

  $Log$
  Revision 1.8  2003-05-15 22:50:50  jonas
    * the stat type is processor-dependent
    * the dev_t tpye is processor dependent. Don't use it in the stat type
      however, as that one is also used at a time where dev_t is already
      defined as qword

  Revision 1.7  2002/09/07 16:01:20  peter
    * old logs removed and tabs fixed

  Revision 1.6  2002/07/29 17:50:02  florian
    + added register location description for ppc
