Patch for Pavel against 2.6.13-rc3-mm3 (after removal of the TIF_FREEZE 
patch). The same patch was posted yesterday against 2.6.13-rc3. I verified
again that this patch works fine on i386.

---

Allow notifier to remove itself.
This is done by retrieving the pointer to the next notifier from the list 
before the
notifier call.
