ok. i see. so i can now set the syscall table to the 'real' location
for the afs_syscall routine.  however, i still run into trouble
when invoking the syscall:

>>IP;  a000000000034250 <[mysyscall].text.end+11/31>   <==>>b0;  a0000000000340e0 <[mysyscall].text.start+20/40>

Trace; a0000000000340e0 <[mysyscall].text.start+20/40>

i suspect that my afs_syscall() is trying to use the 'gp' which is
probably not setup?
