      [PATCH] ia64: Fix OSDL BugMe report 2885: realtime process can't preempt low priority process in kernel
      
      Rearranged code to make it work. There were two problems:
      
       1. The preempt flag was being tested only if code was leaving for
          user space (the logic should be: test for RESCHEDULE if we're
          switching to a kernel thread, test everything if switching to a
          user thread)
      
       2. The check of the user space flags was being repeated even if the
          work had been done.
      
      There is one small change in semantics: when returning from a
      preemption, the preemption flag will *not* be rechecked.  Otherwise, I
      found that it was easy to get into a livelock situation where no
      forward progress was made.
