      Pull networking fixes from David Miller:
       "Here is a quick pull request primarily meant to address the deconfig
        fallout from changing SCSI_NETLINK from being used via 'select' to
        being used via 'depends'.
      
        I applied a set of 5 patches written by Michal Marek, and then I
        carefully audited all of the remaining config files, basically:
      
         1) I scanned every arch config file, and if it mentioned CONFIG_INET
            or CONFIG_UNIX, I made sure it had CONFIG_NET=y
      
         2) After that, I scanned every arch config file, and if it did not
            have CONFIG_NET=y I made sure it did not reference any networking
            config options.
      
        Finally, we have some late breaking wireless fixes in here from John
        Linville and co"

      - fix BPF_LD|ABS|IND from negative offsets:
        make sure to sign extend lower 32 bits in 64-bit register
        before calling C helpers from JITed code, otherwise 'int k'
        argument of bpf_internal_load_pointer_neg_helper() function
        will be added as large unsigned integer, causing packet size
        check to trigger and abort the program.
      
        It's worth noting that JITed code for 'A = A op K' will affect
        upper 32 bits differently depending whether K is simm13 or not.
        Since small constants are sign extended, whereas large constants
        are stored in temp register and zero extended.
        That is ok and we don't have to pay a penalty of sign extension
        for every sethi, since all classic BPF instructions have 32-bit
        semantics and we only need to set correct upper bits when
        transitioning from JITed code into C.
      
      - though instructions 'A &= 0' and 'A *= 0' are odd, JIT compiler
        should not optimize them out

      For the NFC bits, Samuel says:
      
      "Hopefully not too late for a handful of NFC fixes:
      
      - 2 potential build failures for ST21NFCA and ST21NFCB, triggered by a
        depmod dependenyc cycle.
      - One potential buffer overflow in the microread driver."

      Emil Goode provides a fix for a brcmfmac off-by-one regression which
      was introduced in the 3.17 cycle.
      
      Loic Poulain fixes a polarity mismatch for a variable assignment
      inside of rfkill-gpio.

       "We've had an issue with scsi-mq where probing takes forever.  This was

        creates and destroys tons of queues, so this let to 10s of seconds of

        Tejun has a real fix for this, but it's too involved for 3.17.  So
        this is a temporary workaround to expedite the queue killing until we

      blk-mq, percpu_ref: implement a kludge for SCSI blk-mq stall during probe · 0a30288d
      Tejun Heo authored
      
      
      blk-mq uses percpu_ref for its usage counter which tracks the number
      of in-flight commands and used to synchronously drain the queue on
      freeze.  percpu_ref shutdown takes measureable wallclock time as it
      involves a sched RCU grace period.  This means that draining a blk-mq
      takes measureable wallclock time.  One would think that this shouldn't
      matter as queue shutdown should be a rare event which takes place
      asynchronously w.r.t. userland.
      
      Unfortunately, SCSI probing involves synchronously setting up and then
      tearing down a lot of request_queues back-to-back for non-existent
      LUNs.  This means that SCSI probing may take more than ten seconds
      when scsi-mq is used.
      
      This will be properly fixed by implementing a mechanism to keep
      q->mq_usage_counter in atomic mode till genhd registration; however,
      that involves rather big updates to percpu_ref which is difficult to
      apply late in the devel cycle (v3.17-rc6 at the moment).  As a
      stop-gap measure till the proper fix can be implemented in the next
      cycle, this patch introduces __percpu_ref_kill_expedited() and makes
      blk_mq_freeze_queue() use it.  This is heavy-handed but should work
      for testing the experimental SCSI blk-mq implementation.

      crypto: aesni - disable "by8" AVX CTR optimization · 7da4b29d
      Mathias Krause authored
      The "by8" implementation introduced in commit 22cddcc7
      
       ("crypto: aes
      - AES CTR x86_64 "by8" AVX optimization") is failing crypto tests as it
      handles counter block overflows differently. It only accounts the right
      most 32 bit as a counter -- not the whole block as all other
      implementations do. This makes it fail the cryptomgr test #4 that
      specifically tests this corner case.
      
      As we're quite late in the release cycle, just disable the "by8" variant
      for now.

      crypto: ccp - Check for CCP before registering crypto algs · c9f21cb6
      Tom Lendacky authored
      
      
      If the ccp is built as a built-in module, then ccp-crypto (whether
      built as a module or a built-in module) will be able to load and
      it will register its crypto algorithms.  If the system does not have
      a CCP this will result in -ENODEV being returned whenever a command
      is attempted to be queued by the registered crypto algorithms.
      
      Add an API, ccp_present(), that checks for the presence of a CCP
      on the system.  The ccp-crypto module can use this to determine if it
      should register it's crypto alogorithms.

         - A few fixes from me:
      
              - Ensure that request deadline/timeout is ordered before the
                request is marked as started.
      
              - A potential oops on out-of-memory, when we scale the queue
                depth of the device and retry.
      
              - A hang fix on requeue from SCSI, where the hardware queue
                would be stopped when we attempt to re-run it (and hence
                nothing would happen, stalling progress).
      
              - A fix for commit 2da78092, where the cleanup path was moved
                to RCU, but a debug might_sleep() was inadvertently left in
                the code.  This causes warnings for people"

      parisc: Only use -mfast-indirect-calls option for 32-bit kernel builds · d26a7730
      John David Anglin authored
      
      
      In spite of what the GCC manual says, the -mfast-indirect-calls has
      never been supported in the 64-bit parisc compiler. Indirect calls have
      always been done using function descriptors irrespective of the
      -mfast-indirect-calls option.
      
      Recently, it was noticed that a function descriptor was always requested
      when the -mfast-indirect-calls option was specified. This caused
      problems when the option was used in  application code and doesn't make
      any sense because the whole point of the option is to avoid using a
      function descriptor for indirect calls.
      
      Fixing this broke 64-bit kernel builds.
      
      I will fix GCC but for now we need the attached change. This results in
      the same kernel code as before.

      brcmfmac: Fix off by one bug in brcmf_count_20mhz_channels() · f8adaf0a
      Emil Goode authored
      In the brcmf_count_20mhz_channels function we are looping through a list
      of channels received from firmware. Since the index of the first channel
      is 0 the condition leads to an off by one bug. This is causing us to hit
      the WARN_ON_ONCE(1) calls in the brcmu_d11n_decchspec function, which is
      how I discovered the bug.
