I was suggesting to use the list of syscalls in the sparc64 code
in a generic spot, making a table indexed by __NR_* number
that the tracehook syscall stuff can use.

But yes, there are other issues such as datastructure layout.

It all depends upon what Roland thinks those arg values obtained by
the asm/syscall.h functions should mean.
