      NFSv4.1 fix infinite loop on IO BAD_STATEID error · 0e3d3e5d
      Olga Kornievskaia authored
      Commit 63d63cbf "NFSv4.1: Don't recheck delegations that
      have already been checked" introduced a regression where when a
      client received BAD_STATEID error it would not send any TEST_STATEID
      and instead go into an infinite loop of resending the IO that caused
      the BAD_STATEID.

      ALSA: hda - fix a problem for lineout on a Dell AIO machine · 2f726aec
      Hui Wang authored
      On this Dell AIO machine, the lineout jack does not work.
      
      We found the pin 0x1a is assigned to lineout on this machine, and in
      the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
      heaset-set mic problem for this machine, this fixup will redefine
      the pin 0x1a to headphone-mic, as a result the lineout doesn't
      work anymore.
      
      After consulting with Dell, they told us this machine doesn't support
      microphone via headset jack, so we add a new fixup which only defines
      the pin 0x18 as the headset-mic.
      
      [rearranged the fixup insertion position by tiwai in order to make the
       merge with other branches easier -- tiwai]
      
      Fixes: 59ec4b57

      ARCv2: SLC: Make sure busy bit is set properly on SLC flushing · c70c4733
      Alexey Brodkin authored
      
      
      As reported in STAR 9001165532, an SLC control reg read (for checking
      busy state) right after SLC invalidate command may incorrectly return
      NOT busy causing software to NOT spin-wait while operation is underway.
      (and for some reason this only happens if L1 cache is also disabled - as
      required by IOC programming model)
      
      Suggested workaround is to do an additional Control Reg read, which
      ensures the 2nd read gets the right status.

           with a scheduler enabled.

      cpuidle: powernv: Pass correct drv->cpumask for registration · 293d264f
      Vaidyanathan Srinivasan authored
      
      
      drv->cpumask defaults to cpu_possible_mask in __cpuidle_driver_init().
      On PowerNV platform cpu_present could be less than cpu_possible in cases
      where firmware detects the cpu, but it is not available to the OS.  When
      CONFIG_HOTPLUG_CPU=n, such cpus are not hotplugable at runtime and hence
      we skip creating cpu_device.
      
      This breaks cpuidle on powernv where register_cpu() is not called for
      cpus in cpu_possible_mask that cannot be hot-added at runtime.
      
      Trying cpuidle_register_device() on cpu without cpu_device will cause
      crash like this:

      Merge branch 'regset' (PTRACE_SETREGSET data leakage) · 72c33734
      Linus Torvalds authored
      Merge PTRACE_SETREGSET leakage fixes from Dave Martin:
       "This series is the collection of fixes I proposed on this topic, that
        have not yet appeared upstream or in the stable branches,
      
        The issue can leak kernel stack, but doesn't appear to allow userspace
        to attack the kernel directly.  The affected architectures are c6x,
        h8300, metag, mips and sparc.
      
        [ Mark Salter points out that c6x has no MMU or other mechanism to
          prevent userspace access to kernel code or data on c6x, but it
          doesn't hurt to clean that case up too. ]
      
        The bugs arise from use of user_regset_copyin(). Users of
        user_regset_copyin() can work in one of two ways:
      
         1) Copy directly to thread_struct or equivalent. (This seems to be
            the design assumption of the regset API, and is the most common
            approach.)
      
         2) Copy to a local variable and then transfer to thread_struct. (A
            significant minority of cases.)
      
        Buggy code typically involves approach 2"
