      handles it correctly (seeks by PAGE_SIZE - sizeof(struct user),

        since it fixes a problem where multiplatform kernels panic on all but

      smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu(). · f21afc25
      David Daney authored
      Thanks to commit f91eb62f ("init: scream bloody murder if interrupts
      are enabled too early"), "bloody murder" is now being screamed.
      With a MIPS OCTEON config, we use on_each_cpu() in our
      irq_chip.irq_bus_sync_unlock() function.  This gets called in early as a
      result of the time_init() call.  Because the !SMP version of
      on_each_cpu() unconditionally enables irqs, we get:
          WARNING: at init/main.c:560 start_kernel+0x250/0x410()
          Interrupts were enabled early
          CPU: 0 PID: 0 Comm: swapper Not tainted 3.10.0-rc5-Cavium-Octeon+ #801
          Call Trace:
      Suggested fix: Do what we already do in the SMP version of
      on_each_cpu(), and use local_irq_save/local_irq_restore.  Because we
      need a flags variable, make it a static inline to avoid name space
      [ Change from v1: Convert on_each_cpu to a static inline function, add
        #include <linux/irqflags.h> to avoid build breakage on some files.
        on_each_cpu_mask() and on_each_cpu_cond() suffer the same problem as
        on_each_cpu(), but they are not causing !SMP bugs for me, so I will
        defer changing them to a less urgent patch. ]

      powerpc: Fix missing/delayed calls to irq_work · 230b3034
      Benjamin Herrenschmidt authored
      When replaying interrupts (as a result of the interrupt occurring
      while soft-disabled), in the case of the decrementer, we are exclusively
      testing for a pending timer target. However we also use decrementer
      interrupts to trigger the new "irq_work", which in this case would
      be missed.
      This change the logic to force a replay in both cases of a timer
      boundary reached and a decrementer interrupt having actually occurred
      while disabled. The former test is still useful to catch cases where
      a CPU having been hard-disabled for a long time completely misses the
      interrupt due to a decrementer rollover.

      powerpc: Fix emulation of illegal instructions on PowerNV platform · bf593907
      Paul Mackerras authored
      Normally, the kernel emulates a few instructions that are unimplemented
      on some processors (e.g. the old dcba instruction), or privileged (e.g.
      mfpvr).  The emulation of unimplemented instructions is currently not
      working on the PowerNV platform.  The reason is that on these machines,
      unimplemented and illegal instructions cause a hypervisor emulation
      assist interrupt, rather than a program interrupt as on older CPUs.
      Our vector for the emulation assist interrupt just calls
      program_check_exception() directly, without setting the bit in SRR1
      that indicates an illegal instruction interrupt.  This fixes it by
      making the emulation assist interrupt set that bit before calling
      program_check_interrupt().  With this, old programs that use no-longer
      implemented instructions such as dcba now work again.

      powerpc: Fix stack overflow crash in resume_kernel when ftracing · 0e37739b
      Michael Ellerman authored
      It's possible for us to crash when running with ftrace enabled, eg:
        Bad kernel stack pointer bffffd12 at c00000000000a454

      If we look at current's stack (paca->__current->stack) we see it is

        ... and so on
      __ppc64_runlatch_on() is called from RUNLATCH_ON in the exception entry
      path. At that point the irq state is not consistent, ie. interrupts are
      hard disabled (by the exception entry), but the paca soft-enabled flag
      may be out of sync.
      This leads to the local_irq_restore() in trace_graph_entry() actually
      enabling interrupts, which we do not want. Because we have not yet
      reprogrammed the decrementer we immediately take another decrementer
      exception, and recurse.
      The fix is twofold. Firstly make sure we call DISABLE_INTS before
      calling RUNLATCH_ON. The badly named DISABLE_INTS actually reconciles
      the irq state in the paca with the hardware, making it safe again to
      call local_irq_save/restore().
      Although that should be sufficient to fix the bug, we also mark the
      runlatch routines as notrace. They are called very early in the
      exception entry and we are asking for trouble tracing them. They are
      also fairly uninteresting and tracing them just adds unnecessary
      [ This regression was introduced by fe1952fc
