      Pull powerpc fixes from Michael Ellerman:
      
       - Add perf support for emitting extended registers for power10.
      
       - A fix for CPU hotplug on pseries, where on large/loaded systems we
         may not wait long enough for the CPU to be offlined, leading to
         crashes.
      
       - Addition of a raw cputable entry for Power10, which is not required
         to boot, but is required to make our PMU setup work correctly in
         guests.
      
       - Three fixes for the recent changes on 32-bit Book3S to move modules
         into their own segment for strict RWX.
      
       - A fix for a recent change in our powernv PCI code that could lead to
         crashes.
      
       - A change to our perf interrupt accounting to avoid soft lockups when
         using some events, found by syzkaller.
      
       - A change in the way we handle power loss events from the hypervisor
         on pseries. We no longer immediately shut down if we're told we're
         running on a UPS.
      
       - A few other minor fixes.

      Pull x86 fix from Thomas Gleixner:
       "A single fix for x86 which removes the RDPID usage from the paranoid
        entry path and unconditionally uses LSL to retrieve the CPU number.
      
        RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid
        expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values
        and restores them either when leaving the run loop, on preemption or
        when going out to user space. MSR_TSX_AUX is part of that lazy MSR
        set, so after writing the guest value and before the lazy restore any
        exception using the paranoid entry will read the guest value and use
        it as CPU number to retrieve the GSBASE value for the current CPU when
        FSGSBASE is enabled. As RDPID is only used in that particular entry
        path, there is no reason to burden VMENTER/EXIT with two extra MSR
        writes. Remove the RDPID optimization, which is not even backed by
        numbers from the paranoid entry path instead"

      ALSA: firewire-digi00x: exclude Avid Adrenaline from detection · acd46a6b
      Takashi Sakamoto authored
      Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to.
      However, as long as he investigated, the design of this model is hardly
      similar to the one of Digi 00x family. It's better to exclude the model
      from modalias of ALSA firewire-digi00x driver.
      
      This commit changes device entries so that the model is excluded.

      ALSA; firewire-tascam: exclude Tascam FE-8 from detection · 0bd8bce8
      Takashi Sakamoto authored
      Tascam FE-8 is known to support communication by asynchronous transaction
      only. The support can be implemented in userspace application and
      snd-firewire-ctl-services project has the support. However, ALSA
      firewire-tascam driver is bound to the model.
      
      This commit changes device entries so that the model is excluded. In a
      commit 53b3ffee ("ALSA: firewire-tascam: change device probing
      processing"), I addressed to the concern that version field in
      configuration differs depending on installed firmware. However, as long
      as I checked, the version number is fixed. It's safe to return version
      number back to modalias.

      epoll: Keep a reference on files added to the check list · a9ed4a65
      Marc Zyngier authored
      When adding a new fd to an epoll, and that this new fd is an
      epoll fd itself, we recursively scan the fds attached to it
      to detect cycles, and add non-epool files to a "check list"
      that gets subsequently parsed.
      
      However, this check list isn't completely safe when deletions
      can happen concurrently. To sidestep the issue, make sure that
      a struct file placed on the check list sees its f_count increased,
      ensuring that a concurrent deletion won't result in the file
      disapearing from under our feet.

      net: nexthop: don't allow empty NHA_GROUP · eeaac363
      Nikolay Aleksandrov authored
      Currently the nexthop code will use an empty NHA_GROUP attribute, but it
      requires at least 1 entry in order to function properly. Otherwise we
      end up derefencing null or random pointers all over the place due to not
      having any nh_grp_entry members allocated, nexthop code relies on having at
      least the first member present. Empty NHA_GROUP doesn't make any sense so
      just disallow it.
      Also add a WARN_ON for any future users of nexthop_create_group().
