      Pull powerpc fixes from Benjamin Herrenschmidt:
       "Whenever you have a chance between two dives, you might want to
        consider pulling my merge branch to pickup a few fixes for 3.8 that
        have been accumulating for the last couple of weeks (I was myself
        travelling then on vacation).
      
        Nothing major, just a handful of powerpc bug fixes that I consider
        worth getting in before 3.8 goes final."
      
      And I'll have everybody know that I'm not diving for several days yet.
      Snif.

      powerpc: Max next_tb to prevent from replaying timer interrupt · 689dfa89
      Tiejun Chen authored
      
      
      With lazy interrupt, we always call __check_irq_replaysome with
      decrementers_next_tb to check if we need to replay timer interrupt.
      So in hotplug case we also need to set decrementers_next_tb as MAX
      to make sure __check_irq_replay don't replay timer interrupt
      when return as we expect, otherwise we'll trap here infinitely.

      powerpc/book3e: Disable interrupt after preempt_schedule_irq · 572177d7
      Tiejun Chen authored
      
      
      In preempt case current arch_local_irq_restore() from
      preempt_schedule_irq() may enable hard interrupt but we really
      should disable interrupts when we return from the interrupt,
      and so that we don't get interrupted after loading SRR0/1.

      The calculation for the left shift of the mask OPROFILE_PM_PMCSEL_MSK has an
      error.  The calculation is should be to shift left by (max_cntrs - cntr) times
      the width of the pmsel field width.  However, the #define OPROFILE_MAX_PMC_NUM
      was used instead of OPROFILE_PMSEL_FIELD_WIDTH.  This patch fixes the
      calculation.

      powerpc/pasemi: Fix crash on reboot · 72640d88
      Steven Rostedt authored
      commit f96972f2
      
       "kernel/sys.c: call disable_nonboot_cpus() in
      kernel_restart()"
      
      added a call to disable_nonboot_cpus() on kernel_restart(), which tries
      to shutdown all the CPUs except the first one. The issue with the PA
      Semi, is that it does not support CPU hotplug.
      
      When the call is made to __cpu_down(), it calls the notifiers
      CPU_DOWN_PREPARE, and then tries to take the CPU down.
      
      One of the notifiers to the CPU hotplug code, is the cpufreq. The
      DOWN_PREPARE will call __cpufreq_remove_dev() which calls
      cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O
      that is used by an interrupt that goes off constantly
      (system_reset_common, but it goes off during normal system operations
      too). I'm not sure exactly what this interrupt does.
      
      Running a simple function trace, you can see it goes off quite a bit:
      
      # tracer: function
      #
      #           TASK-PID    CPU#    TIMESTAMP  FUNCTION

      When the region is unmapped, the system crashes with:

      Suravee Suthikulpanit authored
      
      
      The IOMMU may stop processing page translations due to a perceived lack
      of credits for writing upstream peripheral page service request (PPR)
      or event logs. If the L2B miscellaneous clock gating feature is enabled
      the IOMMU does not properly register credits after the log request has
      completed, leading to a potential system hang.
      
      BIOSes are supposed to disable L2B micellaneous clock gating by setting
      L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This
      patch corrects that for those which do not enable this workaround.

      included the wrong logic.  The lvbptr check was incorrectly
      added after the patch was tested.

      John W. Linville says:
      
      ====================
      This is a batch of fixes intende for the 3.8 stream.
      
      Regarding the iwlwifi bits, Johannes says this:
      
      "Please pull to get a single fix from Emmanuel for a bug I introduced due
      to misunderstanding the code."
      
      Regarding the mac80211 bits, Johannes says this:
      
      "I have a few small fixes for you:
       * some mesh frames would cause encryption warnings -- fixes from Bob
       * scanning would pretty much break an association if we transmitted
         anything to the AP while scanning -- fix from Stanislaw
       * mode injection was broken by channel contexts -- fix from Felix
       * FT roaming was broken: hardware crypto would get disabled by it"
      
      Along with that, a handful of other fixes confined to specific drivers.
      
      Avinash Patil fixes a typo in a NULL check in mwifiex.
      
      Larry Finger fixes a build warning in rtlwifi.  Seems safe...
      
      Stanislaw Gruszka fixes iwlegacy to prevent microcode errors when
      switching from IBSS mode to STA mode.
      
      Felix Fietkau provides a trio of ath9k fixes related to proper tuning.
      
      Please let me know if there are problems!
