      Pull ARM SoC fixes from Olof Johansson:
       "A batch of fixes that have come in during the merge window.
      
        Some of them are defconfig updates for things that have now landed,
        some errata additions and a few general scattered fixes.
      
        There's also a qcom DT update that adds support for SATA on AP148, and
        basic support for Sony Xperia Z1 and CM-QS600 platforms that seemed
        isolated enough that we could merge it even if it's late"

      Pull audit updates from Eric Paris:
       "So this change across a whole bunch of arches really solves one basic
        problem.  We want to audit when seccomp is killing a process.  seccomp
        hooks in before the audit syscall entry code.  audit_syscall_entry
        took as an argument the arch of the given syscall.  Since the arch is
        part of what makes a syscall number meaningful it's an important part
        of the record, but it isn't available when seccomp shoots the
        syscall...
      
        For most arch's we have a better way to get the arch (syscall_get_arch)
        So the solution was two fold: Implement syscall_get_arch() everywhere
        there is audit which didn't have it.  Use syscall_get_arch() in the
        seccomp audit code.  Having syscall_get_arch() everywhere meant it was
        a useless flag on the stack and we could get rid of it for the typical
        syscall entry.
      
        The other changes inside the audit system aren't grand, fixed some
        records that had invalid spaces.  Better locking around the task comm
        field.  Removing some dead functions and structs.  Make some things
        static.  Really minor stuff"

       "A second (and last) round of late coming fixes and changes, almost all
        of them in perf tooling:
      
        User visible tooling changes:
      
         - Add period data column and make it default in 'perf script' (Jiri
           Olsa)
      
         - Add a visual cue for toggle zeroing of samples in 'perf top'
           (Taeung Song)

           command line combo (Yasser Shalabi)
      
         - Fix off-by-one bugs in map->end handling (Stephane Eranian)
      
         - Fix off-by-one bug in maps__find(), also related to map->end
           handling (Namhyung Kim)
      
         - Make struct symbol->end be the first addr after the symbol range,
           to make it match the convention used for struct map->end.  (Arnaldo
           Carvalho de Melo)
      
         - Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
           live' (Jiri Olsa)
      
         - Fix python test build by moving callchain_param to an object linked
           into the python binding (Jiri Olsa)
      
         - Document sysfs events/ interfaces (Cody P Schafer)
      
         - Fix typos in perf/Documentation (Masanari Iida)
      
         - Add missing 'struct option' forward declaration (Arnaldo Carvalho
           de Melo)
      
         - Add option to copy events when queuing for sorting across cpu
           buffers and enable it for 'perf kvm stat live', to avoid having
           events left in the queue pointing to the ring buffer be rewritten
           in high volume sessions.  (Alexander Yarygin, improving work done
           by David Ahern):
      
         - Do not include a struct hists per perf_evsel, untangling the
           histogram code from perf_evsel, to pave the way for exporting a
           minimalistic tools/lib/api/perf/ library usable by tools/perf and
           initially by the rasd daemon being developed by Borislav Petkov,
           Robert Richter and Jean Pihet.  (Arnaldo Carvalho de Melo)
      
         - Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
           thread maps mean syswide monitoring, reducing the boilerplate for
           tools that only want system wide mode.  (Arnaldo Carvalho de Melo)
      
         - Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
           should be just a front end for exit + free (Arnaldo Carvalho de
           Melo)

      The check for the presence or not of the optional switch function
      get_phy_flags() called the function, rather than checked to see if it
      is a NULL pointer. This causes a derefernce of a NULL pointer on all
      switch chips except the sf2, the only switch to implement this call.

      sparc64: Do not define thread fpregs save area as zero-length array. · e2653143
      David S. Miller authored
      This breaks the stack end corruption detection facility.
      
      What that facility does it write a magic value to "end_of_stack()"
      and checking to see if it gets overwritten.
      
      "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
      the beginning of the FPU register save area.
      
      So once the user uses the FPU, the magic value is overwritten and the
      debug checks trigger.
      
      Fix this by making the size explicit.
      
      Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
      are limited to 7 levels of FPU state saves.  So each FPU register set
      is 256 bytes, allocate 256 * 7 for the fpregs area.

      sparc64: Fix corrupted thread fault code. · 84bd6d8b
      David S. Miller authored
      Every path that ends up at do_sparc64_fault() must install a valid
      FAULT_CODE_* bitmask in the per-thread fault code byte.
      
      Two paths leading to the label winfix_trampoline (which expects the
      FAULT_CODE_* mask in register %g4) were not doing so:
      
      1) For pre-hypervisor TLB protection violation traps, if we took
         the 'winfix_trampoline' path we wouldn't have %g4 initialized
         with the FAULT_CODE_* value yet.  Resulting in using the
         TLB_TAG_ACCESS register address value instead.
      
      2) In the TSB miss path, when we notice that we are going to use a
         hugepage mapping, but we haven't allocated the hugepage TSB yet, we
         still have to take the window fixup case into consideration and
         in that particular path we leave %g4 not setup properly.
      
      Errors on this sort were largely invisible previously, but after
      commit 4ccb9272 ("sparc64: sun4v TLB
      error power off events") we now have a fault_code mask bit
      (FAULT_CODE_BAD_RA) that triggers due to this bug.
      
      FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
      (see #1 above) and thus we get seemingly random bus errors triggered
      for user processes.

      Pull core block layer changes from Jens Axboe:
       "This is the core block IO pull request for 3.18.  Apart from the new
        and improved flush machinery for blk-mq, this is all mostly bug fixes
        and cleanups.
      
         - blk-mq timeout updates and fixes from Christoph.
      
         - Removal of REQ_END, also from Christoph.  We pass it through the
           ->queue_rq() hook for blk-mq instead, freeing up one of the request
           bits.  The space was overly tight on 32-bit, so Martin also killed
           REQ_KERNEL since it's no longer used.
      
         - blk integrity updates and fixes from Martin and Gu Zheng.
      
         - Update to the flush machinery for blk-mq from Ming Lei.  Now we
           have a per hardware context flush request, which both cleans up the
           code should scale better for flush intensive workloads on blk-mq.
      
         - Improve the error printing, from Rob Elliott.
      
         - Backing device improvements and cleanups from Tejun.
      
         - Fixup of a misplaced rq_complete() tracepoint from Hannes.
      
         - Make blk_get_request() return error pointers, fixing up issues
           where we NULL deref when a device goes bad or missing.  From Joe
           Lawrence.
      
         - Prep work for drastically reducing the memory consumption of dm
           devices from Junichi Nomura.  This allows creating clone bio sets
           without preallocating a lot of memory.
      
         - Fix a blk-mq hang on certain combinations of queue depths and
           hardware queues from me.
      
         - Limit memory consumption for blk-mq devices for crash dump
           scenarios and drivers that use crazy high depths (certain SCSI
           shared tag setups).  We now just use a single queue and limited
           depth for that"

       "Sorry for delaying this a bit later than usual.  There's one mild
        regression from 3.16 that was noticed during the 3.17 cycle, and I
        meant to send a fix for it along with this pull request.  I'll
        probably try to queue it up for a later pull request once I've had a
        better look at it, hopefully by -rc2 at the latest.
      
        Summary for this pull:
      
        NAND
         - Cleanup for Denali driver
         - Atmel: add support for new page sizes

         - Compile-time configuration to select 4K vs.  64K support for flash
           that support both (necessary for using UBIFS on some SPI NOR)

      It seems it's my turn to be the documentation maintainer for a bit.  My
      plan is to work to ensure that docs patches don't fall through the cracks;
      I assume most changes will continue to flow through subsystem-specific
      trees.

      x86,kvm,vmx: Preserve CR4 across VM entry · d974baa3
      Andy Lutomirski authored
      CR4 isn't constant; at least the TSD and PCE bits can vary.
      
      TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
      like it's correct.
      
      This adds a branch and a read from cr4 to each vm entry.  Because it is
      extremely likely that consecutive entries into the same vcpu will have
      the same host cr4 value, this fixes up the vmcs instead of restoring cr4
      after the fact.  A subsequent patch will add a kernel-wide cr4 shadow,
      reducing the overhead in the common case to just two memory reads and a
      branch.
