      Pull asm-generic fixes from Arnd Bergmann:
       "I have one regression fix for a minor build problem after the
        architecture removal series, plus a rework of the barriers in the
        readl/writel functions, thanks to work by Sinan Kaya:
      
        This started from a discussion on the linuxpcc and rdma mailing
        lists[1]. To summarize, we decided that architectures are responsible
        to serialize readl() and writel() accesses on a device MMIO space
        relative to DMA performed by that device.
      
        This series provides a pessimistic implementation of that behavior for
        asm-generic/io.h, which is in turn used by a number of architectures
        (h8300, microblaze, nios2, openrisc, s390, sparc, um, unicore32, and
        xtensa). Some of those presumably need no extra barriers, or something
        weaker than rmb()/wmb(), and they are advised to override the new
        default for better performance.
      
        For inb()/outb(), the same barriers are used, but architectures might
        want to add another barrier to outb() here if that can guarantee
        non-posted behavior (some architectures can, others cannot do that).
      
        The readl_relaxed()/writel_relaxed() family of functions retains the
        existing behavior with no extra barriers"

      Linus Torvalds authored
      Pull more power management updates from Rafael Wysocki:
       "These include one big-ticket item which is the rework of the idle loop
        in order to prevent CPUs from spending too much time in shallow idle
        states. It reduces idle power on some systems by 10% or more and may
        improve performance of workloads in which the idle loop overhead
        matters. This has been in the works for several weeks and it has been
        tested and reviewed quite thoroughly.
      
        Also included are changes that finalize the cpufreq cleanup moving
        frequency table validation from drivers to the core, a few fixes and
        cleanups of cpufreq drivers, a cpuidle documentation update and a PM
        QoS core update to mark the expected switch fall-throughs in it.
      
        Specifics:
      
         - Rework the idle loop in order to prevent CPUs from spending too
           much time in shallow idle states by making it stop the scheduler
           tick before putting the CPU into an idle state only if the idle
           duration predicted by the idle governor is long enough.
      
           That required the code to be reordered to invoke the idle governor
           before stopping the tick, among other things (Rafael Wysocki,
           Frederic Weisbecker, Arnd Bergmann).
      
         - Add the missing description of the residency sysfs attribute to the
           cpuidle documentation (Prashanth Prakash).
      
         - Finalize the cpufreq cleanup moving frequency table validation from
           drivers to the core (Viresh Kumar).
      
         - Fix a clock leak regression in the armada-37xx cpufreq driver
           (Gregory Clement).
      
         - Fix the initialization of the CPU performance data structures for
           shared policies in the CPPC cpufreq driver (Shunyong Yang).
      
         - Clean up the ti-cpufreq, intel_pstate and CPPC cpufreq drivers a
           bit (Viresh Kumar, Rafael Wysocki).
      
         - Mark the expected switch fall-throughs in the PM QoS core (Gustavo
           Silva)"

      ====================
      l2tp: tunnel creation fixes
      
      L2TP tunnel creation is racy. We need to make sure that the tunnel
      returned by l2tp_tunnel_create() isn't going to be freed while the
      caller is using it. This is done in patch #1, by separating tunnel
      creation from tunnel registration.
      
      With the tunnel registration code in place, we can now check for
      duplicate tunnels in a race-free way. This is done in patch #2, which
      incidentally removes the last use of l2tp_tunnel_find().

      l2tp: fix race in duplicate tunnel detection · f6cd651b
      Guillaume Nault authored
      We can't use l2tp_tunnel_find() to prevent l2tp_nl_cmd_tunnel_create()
      from creating a duplicate tunnel. A tunnel can be concurrently
      registered after l2tp_tunnel_find() returns. Therefore, searching for
      duplicates must be done at registration time.
      
      Finally, remove l2tp_tunnel_find() entirely as it isn't use anywhere
      anymore.

      l2tp: fix races in tunnel creation · 6b9f3423
      Guillaume Nault authored
      l2tp_tunnel_create() inserts the new tunnel into the namespace's tunnel
      list and sets the socket's ->sk_user_data field, before returning it to
      the caller. Therefore, there are two ways the tunnel can be accessed
      and freed, before the caller even had the opportunity to take a
      reference. In practice, syzbot could crash the module by closing the
      socket right after a new tunnel was returned to pppol2tp_create().
      
      This patch moves tunnel registration out of l2tp_tunnel_create(), so
      that the caller can safely hold a reference before publishing the
      tunnel. This second step is done with the new l2tp_tunnel_register()
      function, which is now responsible for associating the tunnel to its
      socket and for inserting it into the namespace's list.
      
      While moving the code to l2tp_tunnel_register(), a few modifications
      have been done. First, the socket validation tests are done in a helper
      function, for clarity. Also, modifying the socket is now done after
      having inserted the tunnel to the namespace's tunnels list. This will
      allow insertion to fail, without having to revert theses modifications
      in the error path (a followup patch will check for duplicate tunnels
      before insertion). Either the socket is a kernel socket which we
      control, or it is a user-space socket for which we have a reference on
      the file descriptor. In any case, the socket isn't going to be closed
      from under us.

      tun: send netlink notification when the device is modified · 83c1f36f

      commit 1ec010e7
      
       ("tun: export flags, uid, gid, queue information

      lan78xx: Don't reset the interface on open · 47b99865
      Phil Elwell authored
      Commit 92571a1a ("lan78xx: Connect phy early") moves the PHY
      initialisation into lan78xx_probe, but lan78xx_open subsequently calls
      lan78xx_reset. As well as forcing a second round of link negotiation,
      this reset frequently prevents the phy interrupt from being generated
      (even though the link is up), rendering the interface unusable.
      
      Fix this issue by removing the lan78xx_reset call from lan78xx_open.

      bnxt_en: Fix NULL pointer dereference at bnxt_free_irq(). · cb98526b
      Michael Chan authored
      When open fails during ethtool -L ring change, for example, the driver
      may crash at bnxt_free_irq() because bp->bnapi is NULL.
      
      If we fail to allocate all the new rings, bnxt_open_nic() will free
      all the memory including bp->bnapi.  Subsequent call to bnxt_close_nic()
      will try to dereference bp->bnapi in bnxt_free_irq().
      
      Fix it by checking for !bp->bnapi in bnxt_free_irq().

      bnxt_en: do not allow wildcard matches for L2 flows · e85a9be9
      Andy Gospodarek authored
      Before this patch the following commands would succeed as far as the
      user was concerned:
      
      $ tc qdisc add dev p1p1 ingress
      $ tc filter add dev p1p1 parent ffff: protocol all \
      	flower skip_sw action drop
      $ tc filter add dev p1p1 parent ffff: protocol ipv4 \
      	flower skip_sw src_mac 00:02:00:00:00:01/44 action drop
      
      The current flow offload infrastructure used does not support wildcard
      matching for ethernet headers, so do not allow the second or third
      commands to succeed.  If a user wants to drop traffic on that interface
      the protocol and MAC addresses need to be specified explicitly:
      
      $ tc qdisc add dev p1p1 ingress
      $ tc filter add dev p1p1 parent ffff: protocol arp \
      	flower skip_sw action drop
      $ tc filter add dev p1p1 parent ffff: protocol ipv4 \
      	flower skip_sw action drop
      ...
      $ tc filter add dev p1p1 parent ffff: protocol ipv4 \
      	flower skip_sw src_mac 00:02:00:00:00:01 action drop
      $ tc filter add dev p1p1 parent ffff: protocol ipv4 \
      	flower skip_sw src_mac 00:02:00:00:00:02 action drop
      ...
      
      There are also checks for VLAN parameters in this patch as other callers
      may wildcard those parameters even if tc does not.  Using different
      flow infrastructure could allow this to work in the future for L2 flows,
      but for now it does not.

      xarray: add the xa_lock to the radix_tree_root · f6bb2a2c
      Matthew Wilcox authored
      This results in no change in structure size on 64-bit machines as it
      fits in the padding between the gfp_t and the void *.  32-bit machines
      will grow the structure from 8 to 12 bytes.  Almost all radix trees are
      protected with (at least) a spinlock, so as they are converted from
      radix trees to xarrays, the data structures will shrink again.
      
      Initialising the spinlock requires a name for the benefit of lockdep, so
      RADIX_TREE_INIT() now needs to know the name of the radix tree it's
      initialising, and so do IDR_INIT() and IDA_INIT().
      
      Also add the xa_lock() and xa_unlock() family of wrappers to make it
      easier to use the lock.  If we could rely on -fplan9-extensions in the
      compiler, we could avoid all of this syntactic sugar, but that wasn't
      added until gcc 4.6.
