      [PATCH] s390: remove pagex support · d4b68996
      Martin Schwidefsky authored
      
      
      Remove pagex pseudo page fault code.  It does not work together with the
      system call speedup that makes the complete system call path enabled for
      interrupts.  To make pagex and the syscall speedup code work together we would
      have to add code to the program check handler to do a critical section cleanup
      like the asynchronous interrupt code.  This would make program checks slower.
      Not what we want.
      
      Newer versions of z/VM have the improved pfault pseudo page fault interface.
      This replaces the old pagex interface and does not have the problem.  So its
      better to just rip out the pagex code.

      [PATCH] s390: pfault interrupt race · b6d09449
      Martin Schwidefsky authored
      
      
      There is a race in pfault_interrupt.  That function gets called two times for
      each pfault notification.  Once with a subcode of 0 to indicate that a real
      page is not available and once with a subcode of 0x80 to indicate that the
      page is present again.
      
      Since the two external interrupts can be delivered on two different cpus the
      order in which the two calls are made is unpredictable.  It is possible that
      the subcode 0x80 interrupt is completed before the subcode 0x00 interrupt has
      done the wake_up() call.
      
      To avoid calling wake_up() on an already removed task structure proper task
      structure reference counting is needed.  Increase the reference counter in the
      subcode 0x00 interrupt before setting pfault_wait to zero and return the
      reference after the wake_up call.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
