/* Kernel syscall interface:
   Input:
       0   - system call number
       3-8 - arguments, as in C
   Output:
       so - (summary overflow) clear iff successful

   This macro is similar to SYSCALL in asm.h, but not completely.
   There's room for optimization, if we assume this will continue to
   be assembled as one file.

   This macro expansions does not include the return instruction.
   If there's no other work to be done, use something like:
       SYSCALL(foo) ; ret
   If there is other work to do (in fork, maybe?), do it after the
   SYSCALL invocation.  */
