      Pull clk framework updates from Michael Turquette:
       "The clk framework and driver changes for 4.5 look pretty typical.  The
        bulk of the changes are to clk controller drivers, though some
        improvements to the core and some re-usable blocks/templates also
        received some love.
      
        In this past cycle the clk maintainers developed a good workflow for
        handling the common case of patch submissions containing a new
        drivers, new shared Device Tree header and a new Device Tree binding
        description.  This requires coordination with the Device Tree
        maintainers and with the architecture maintainers (typically the
        arm-soc tree in our case).
      
        This explains the increase in changes to include/dt-bindings/... and
        to Documentation/devicetree/bindings/clock/... coming from the clk
        tree.  The same commits can be expected to come through those trees on
        occasion, through the use of shared, immutable branches"

      bridge: fix lockdep addr_list_lock false positive splat · c6894dec
      Nikolay Aleksandrov authored
      After promisc mode management was introduced a bridge device could do
      dev_set_promiscuity from its ndo_change_rx_flags() callback which in
      turn can be called after the bridge's addr_list_lock has been taken
      (e.g. by dev_uc_add). This causes a false positive lockdep splat because
      the port interfaces' addr_list_lock is taken when br_manage_promisc()
      runs after the bridge's addr list lock was already taken.
      To remove the false positive introduce a custom bridge addr_list_lock
      class and set it on bridge init.
      A simple way to reproduce this is with the following:
      $ brctl addbr br0
      $ ip l add l br0 br0.100 type vlan id 100
      $ ip l set br0 up
      $ ip l set br0.100 up
      $ echo 1 > /sys/class/net/br0/bridge/vlan_filtering
      $ brctl addif br0 eth0
      Splat:

      David Vrabel authored
      Using the MTU or GSO size to determine the number of required guest Rx
      requests for an skb was subtly broken since these value may change at
      runtime.
      
      After 1650d545 (xen-netback: always
      fully coalesce guest Rx packets) we always fully pack a packet into
      its guest Rx slots.  Calculating the number of required slots from the
      packet length is then easy.

      goes to off at some point, which is not the case if the phy is already
      up/connected at startup.
      
      Explicitly turn off the carrier on phy attach, leaving the phy state
      machine to turn the carrier on when it has done the initial negotiation.

      Disabling interrupts with the IDR register does not stop the macb hardware
      from asserting its interrupt line if there are interrupts pending.  Always
      clear the interrupts using ISR, and be sure to write it on hardware that
      is not read-to-clear, like Zynq.  Not doing so will cause interrupts when
      the driver doesn't expect them.

      sctp: support to lookup with ep+paddr in transport rhashtable · 65a5124a
      Xin Long authored
      Now, when we sendmsg, we translate the ep to laddr by selecting the
      first element of the list, and then do a lookup for a transport.
      
      But sctp_hash_cmp() will compare it against asoc addr_list, which may
      be a subset of ep addr_list, meaning that this chosen laddr may not be
      there, and thus making it impossible to find the transport.
      
      So we fix it by using ep + paddr to lookup transports in hashtable. In
      sctp_hash_cmp, if .ep is set, we will check if this ep == asoc->ep,
      or we will do the laddr check.

      zram/zcomp: do not zero out zcomp private pages · e02d238c
      Sergey Senozhatsky authored
      Do not __GFP_ZERO allocated zcomp ->private pages.  We keep allocated
      streams around and use them for read/write requests, so we supply a
      zeroed out ->private to compression algorithm as a scratch buffer only
      once -- the first time we use that stream.  For the rest of IO requests
      served by this stream ->private usually contains some temporarily data
      from the previous requests.

      zram: pass gfp from zcomp frontend to backend · 75d8947a
      Minchan Kim authored
      Each zcomp backend uses own gfp flag but it's pointless because the
      context they could be called is driven by upper layer(ie, zcomp
      frontend).  As well, zcomp frondend could call them in different
      context.  One context(ie, zram init part) is it should be better to make
      sure successful allocation other context(ie, further stream allocation
      part for accelarating I/O speed) is just optional so let's pass gfp down
      from driver (ie, zcomp frontend) like normal MM convention.

      zram: try vmalloc() after kmalloc() · d913897a
      Kyeongdon Kim authored
      When we're using LZ4 multi compression streams for zram swap, we found
      out page allocation failure message in system running test.  That was
      not only once, but a few(2 - 5 times per test).  Also, some failure
      cases were continually occurring to try allocation order 3.
      
      In order to make parallel compression private data, we should call
      kzalloc() with order 2/3 in runtime(lzo/lz4).  But if there is no order
      2/3 size memory to allocate in that time, page allocation fails.  This
      patch makes to use vmalloc() as fallback of kmalloc(), this prevents
      page alloc failure warning.
      
      After using this, we never found warning message in running test, also
      It could reduce process startup latency about 60-120ms in each case.

      zram/zcomp: use GFP_NOIO to allocate streams · 3d5fe03a
      Sergey Senozhatsky authored
      We can end up allocating a new compression stream with GFP_KERNEL from
      within the IO path, which may result is nested (recursive) IO
      operations.  That can introduce problems if the IO path in question is a
      reclaimer, holding some locks that will deadlock nested IOs.
      
      Allocate streams and working memory using GFP_NOIO flag, forbidding
      recursive IO and FS operations.

      The source code about the subctrl is dealt syscon, but dts doesn't.
