Hello.

I beleive this patch against entry.S should be sufficient:

--- entry.S~ Sat Jul 6 21:01:16 2002
+++ entry.S Sat Jul 6 21:06:14 2002

testb $_TIF_NEED_RESCHED, %cl
jz work_notifysig
work_resched:
- call schedule
+ call schedule_userspace
cli # make sure we don't miss an
interrupt
# setting need_resched or
sigpending
# between sampling and the iret

Both calls to schedule() at resume_kernel: and work_pending:
have clear kernel/user return path.

And users of __KERNEL_SYSCALLS__ and kernel_thread() should not
have policy == SCHED_BATCH.

No?
