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>
>>b6; e000000004402f60 <demine_args+0/a0>
>>b7; e0000000044157b0 <ia64_switch_to+b0/120>
Trace; e00000000441a080 <show_stack+40/c0>
Trace; e00000000441a840 <show_regs+740/780>
Trace; e00000000442b830 <die_if_kernel+70/140>
Trace; e000000004443fc0 <ia64_do_page_fault+760/800>
Trace; e000000004415d00 <ia64_leave_kernel+0/2a0>
Trace; a000000000034250 <[mysyscall].text.end+11/31>
Trace; 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?
