Excuse me for putting a tentative question.
I have a obscure problem of pagefault at unlikely address
that is pinned down to ret_from_sys_call called from
nopage_tlbl -> DO_FAULT -> ret_from_sys_call(nowdays ret_from
tion) during execing userspace programmes.
also due to sone resons out of my control my working source tree
appears to be hacked too much.
I have one entry.S in linux 2.4.17 having top line like
/* $Id: entry.S,v 1.19 1999/12/08 22:05:10 harald Exp
with ret_from_sys_call like
/* Check to see if the current task
* needs to be resscheduled
lw t2, TASK_NEED_RESCHED($28)
bnez t2, reschedule
and one entry.S in some earlier version of entry.S with top line
/* $Id: entry.S,v 220.127.116.11 2001/04/30 10:53:58 carstenl Exp $
here the ret_from_sys_call is just Blank like this
i am curently using this later one .
but i amn't able to follow the changes for ret_from_sys_call
between these two versions.
