      Revert "ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs" · 2b844ba7
      Rafael J. Wysocki authored
      This reverts commit f6308b36 (ACPI: Add BayTrail SoC GPIO and LPSS
      ACPI IDs), because it causes the Alan Cox' ASUS T100TA to "crash and
      burn" during boot if the Baytrail pinctrl driver is compiled in.

      Pull networking fixes from David Miller:
      
       1) The value choosen for the new SO_MAX_PACING_RATE socket option on
          parisc was very poorly choosen, let's fix it while we still can.
          From Eric Dumazet.
      
       2) Our generic reciprocal divide was found to handle some edge cases
          incorrectly, part of this is encoded into the BPF as deep as the JIT
          engines themselves.  Just use a real divide throughout for now.
          From Eric Dumazet.
      
       3) Because the initial lookup is lockless, the TCP metrics engine can
          end up creating two entries for the same lookup key.  Fix this by
          doing a second lookup under the lock before we actually create the
          new entry.  From Christoph Paasch.
      
       4) Fix scatter-gather list init in usbnet driver, from Bjørn Mork.
      
       5) Fix unintended 32-bit truncation in cxgb4 driver's bit shifting.
          From Dan Carpenter.
      
       6) Netlink socket dumping uses the wrong socket state for timewait
          sockets.  Fix from Neal Cardwell.
      
       7) Fix netlink memory leak in ieee802154_add_iface(), from Christian
          Engelmayer.
      
       8) Multicast forwarding in ipv4 can overflow the per-rule reference
          counts, causing all multicast traffic to cease.  Fix from Hannes
          Frederic Sowa.
      
       9) via-rhine needs to stop all TX queues when it resets the device,
          from Richard Weinberger.
      
      10) Fix RDS per-cpu accesses broken by the this_cpu_* conversions.  From
          Gerald Schaefer.

      s390/bpf,jit: fix 32 bit divisions, use unsigned divide instructions · 3af57f78
      Heiko Carstens authored
      
      
      The s390 bpf jit compiler emits the signed divide instructions "dr" and "d"
      for unsigned divisions.
      This can cause problems: the dividend will be zero extended to a 64 bit value
      and the divisor is the 32 bit signed value as specified A or X accumulator,
      even though A and X are supposed to be treated as unsigned values.
      
      The divide instrunctions will generate an exception if the result cannot be
      expressed with a 32 bit signed value.
      This is the case if e.g. the dividend is 0xffffffff and the divisor either 1
      or also 0xffffffff (signed: -1).
      
      To avoid all these issues simply use unsigned divide instructions.

      ipv6: simplify detection of first operational link-local address on interface · 11ffff75
      Hannes Frederic Sowa authored
      In commit 1ec047eb ("ipv6: introduce per-interface counter for
      dad-completed ipv6 addresses") I build the detection of the first
      operational link-local address much to complex. Additionally this code
      now has a race condition.
      
      Replace it with a much simpler variant, which just scans the address
      list when duplicate address detection completes, to check if this is
      the first valid link local address and send RS and MLD reports then.

      tcp: metrics: Avoid duplicate entries with the same destination-IP · 77f99ad1
      Christoph Paasch authored
      Because the tcp-metrics is an RCU-list, it may be that two
      soft-interrupts are inside __tcp_get_metrics() for the same
      destination-IP at the same time. If this destination-IP is not yet part of
      the tcp-metrics, both soft-interrupts will end up in tcpm_new and create
      a new entry for this IP.
      So, we will have two tcp-metrics with the same destination-IP in the list.
      
      This patch checks twice __tcp_get_metrics(). First without holding the
      lock, then while holding the lock. The second one is there to confirm
      that the entry has not been added by another soft-irq while waiting for
      the spin-lock.
      
      Fixes: 51c5d0c4
      
       (tcp: Maintain dynamic metrics in local cache.)

      net: rds: fix per-cpu helper usage · c196403b
      Gerald Schaefer authored
      commit ae4b46e9
      
       "net: rds: use this_cpu_* per-cpu helper" broke per-cpu
      handling for rds. chpfirst is the result of __this_cpu_read(), so it is
      an absolute pointer and not __percpu. Therefore, __this_cpu_write()
      should not operate on chpfirst, but rather on cache->percpu->first, just
      like __this_cpu_read() did before.

        address in detail before I sent this pull request.  Unfortunately a
        bad round of colds kept from addressing that in detail until today.
        The executive summary of the review was:
      
        Al: Is patching d_path really sufficient?
            The prepend_path, d_path, d_absolute_path, and __d_path family of
            functions is a really mess.
      
        Me: Yes, patching d_path is really sufficient.  Yes, the code is mess.
            No it is not appropriate to rewrite all of d_path for a regression
            that has existed for entirely too long already, when a two line
            change will do"

      lib/percpu_counter.c: fix __percpu_counter_add() · 74e72f89
      Ming Lei authored
      
      
      __percpu_counter_add() may be called in softirq/hardirq handler (such
      as, blk_mq_queue_exit() is typically called in hardirq/softirq handler),
      so we need to call this_cpu_add()(irq safe helper) to update percpu
      counter, otherwise counts may be lost.
      
      This fixes the problem that 'rmmod null_blk' hangs in blk_cleanup_queue()
      because of miscounting of request_queue->mq_usage_counter.
      
      This patch is the v1 of previous one of "lib/percpu_counter.c:
      disable local irq when updating percpu couter", and takes Andrew's
      approach which may be more efficient for ARCHs(x86, s390) that
      have optimized this_cpu_add().
