      Pull documentation updates from Jonathan Corbet:
       "Some big changes this month, headlined by the addition of a new
        formatted documentation mechanism based on the Sphinx system.
      
        The objectives here are to make it easier to create better-integrated
        (and more attractive) documents while (eventually) dumping our
        one-of-a-kind, cobbled-together system for something that is widely
        used and maintained by others.  There's a fair amount of information
        what's being done, why, and how to use it in:
      
          https://lwn.net/Articles/692704/
          https://lwn.net/Articles/692705/
      
        Closer to home, Documentation/kernel-documentation.rst describes how
        it works.
      
        For now, the new system exists alongside the old one; you should soon
        see the GPU documentation converted over in the DRM pull and some
        significant media conversion work as well.  Once all the docs have
        been moved over and we're convinced that the rough edges (of which are
        are a few) have been smoothed over, the DocBook-based stuff should go
        away.
      
        Primary credit is to Jani Nikula for doing the heavy lifting to make
        this stuff actually work; there has also been notable effort from
        Markus Heiser, Daniel Vetter, and Mauro Carvalho Chehab.
      
        Expect a couple of conflicts on the new index.rst file over the course
        of the merge window; they are trivially resolvable.  That file may be
        a bit of a conflict magnet in the short term, but I don't expect that
        situation to last for any real length of time.
      
        Beyond that, of course, we have the usual collection of tweaks,
        updates, and typo fixes"

      Linus Torvalds authored
      Pull s390 updates from Martin Schwidefsky:
       "There are a couple of new things for s390 with this merge request:
      
         - a new scheduling domain "drawer" is added to reflect the unusual
           topology found on z13 machines.  Performance tests showed up to 8
           percent gain with the additional domain.
      
         - the new crc-32 checksum crypto module uses the vector-galois-field
           multiply and sum SIMD instruction to speed up crc-32 and crc-32c.
      
         - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in
           the generic vmlinux.lds linker script definitions.
      
         - kcov instrumentation support.  A prerequisite for that is the
           inline assembly basic block cleanup, which is the reason for the
           net/iucv/iucv.c change.
      
         - support for 2GB pages is added to the hugetlbfs backend.
      
        Then there are two removals:
      
         - the oprofile hardware sampling support is dead code and is removed.
           The oprofile user space uses the perf interface nowadays.
      
         - the ETR clock synchronization is removed, this has been superseeded
           be the STP clock synchronization.  And it always has been
           "interesting" code..
      
        And the usual bug fixes and cleanups"

      Pull KVM leftovers from Radim Krčmář:
       "This is a combination of two pull requests for 4.7-rc8 that were not
        merged due to looking hairy.  I have changed the tag message to focus
        on circumstances of contained reverts as they were likely the reason
        behind rejection.
      
        This merge introduces three patches that are later reverted,
      
         - Switching of MSR_TSC_AUX in SVM was thought to cause a host
           misbehavior, but it was later cleared of those doubts and the patch
           moved code to a hot path, so we reverted it.  That patch also
           needed a fix for 32 bit builds and both were reverted in one go.
      
         - Al Viro noticed that a fix for a leak in an error path was not
           valid with the given API and provided a better fix, so the original
           patch was reverted.
      
        Then there are two VMX fixes that move code around because VMCS was
        not accessed between vcpu_load() and vcpu_put(), a simple ARM VHE fix,
        and two one-liners for PML and MTRR"

      Pull perf updates from Ingo Molnar:
       "With over 300 commits it's been a busy cycle - with most of the work
        concentrated on the tooling side (as it should).
      
        The main kernel side enhancements were:
      
         - Add per event callchain limit: Recently we introduced a sysctl to
           tune the max-stack for all events for which callchains were
           requested:
      
             $ sysctl kernel.perf_event_max_stack
             kernel.perf_event_max_stack = 127
      
           Now this patch introduces a way to configure this per event, i.e.
           this becomes possible:
      
             $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a
      
           allowing finer tuning of how much buffer space callchains use.
      
           This uses an u16 from the reserved space at the end, leaving
           another u16 for future use.
      
           There has been interest in even finer tuning, namely to control the
           max stack for kernel and userspace callchains separately.  Further
           discussion is needed, we may for instance use the remaining u16 for
           that and when it is present, assume that the sample_max_stack
           introduced in this patch applies for the kernel, and the u16 left
           is used for limiting the userspace callchain (Arnaldo Carvalho de
           Melo)
      
         - Optimize AUX event (hardware assisted side-band event) delivery
           (Kan Liang)
      
         - Rework Intel family name macro usage (this is partially x86 arch
           work) (Dave Hansen)
      
         - Refine and fix Intel LBR support (David Carrillo-Cisneros)
      
         - Add support for Intel 'TopDown' events (Andi Kleen)
      
         - Intel uncore PMU driver fixes and enhancements (Kan Liang)
      
         - ... other misc changes.
      
        Here's an incomplete list of the tooling enhancements (but there's
        much more, see the shortlog and the git log for details):
      
         - Support cross unwinding, i.e.  collecting '--call-graph dwarf'
           perf.data files in one machine and then doing analysis in another
           machine of a different hardware architecture.  This enables, for
           instance, to do:
      
             $ perf record -a --call-graph dwarf
      
           on a x86-32 or aarch64 system and then do 'perf report' on it on a
           x86_64 workstation (He Kuang)
      
         - Allow reading from a backward ring buffer (one setup via
           sys_perf_event_open() with perf_event_attr.write_backward = 1)
           (Wang Nan)
      
         - Finish merging initial SDT (Statically Defined Traces) support, see
           cset comments for details about how it all works (Masami Hiramatsu)
      
         - Support attaching eBPF programs to tracepoints (Wang Nan)
      
         - Add demangling of symbols in programs written in the Rust language
           (David Tolnay)
      
         - Add support for tracepoints in the python binding, including an
           example, that sets up and parses sched:sched_switch events,
           tools/perf/python/tracepoint.py (Jiri Olsa)
      
         - Introduce --stdio-color to set up the color output mode selection
           in 'annotate' and 'report', allowing emit color escape sequences
           when redirecting the output of these tools (Arnaldo Carvalho de
           Melo)
      
         - Add 'callindent' option to 'perf script -F', to indent the Intel PT
           call stack, making this output more ftrace-like (Adrian Hunter,
           Andi Kleen)
      
         - Allow dumping the object files generated by llvm when processing
           eBPF scriptlet events (Wang Nan)
      
         - Add stackcollapse.py script to help generating flame graphs (Paolo
           Bonzini)
      
         - Add --ldlat option to 'perf mem' to specify load latency for loads
           event (e.g. cpu/mem-loads/ ) (Jiri Olsa)
      
         - Tooling support for Intel TopDown counters, recently added to the
           kernel (Andi Kleen)"

      Not needed at all, tools/perf/util/perf_regs.h, included via:
      
        #include "perf_regs.h"
      
      Should have a definition for PERF_REGS_MAX, and since this is dependent
      on HAVE_PERF_REGS_SUPPORT, fixes the build on powerpc, noticed by trying
      to cross compile this from ubuntu16.04 with a locally build libz &
      elfutils pair, since those are not available in multilib packages.

      Linus Torvalds authored
      Pull gfs2 updates from Bob Peterson:
       "We've got ten patches this time, half of which are related to a
        plethora of nasty outcomes when inodes are transitioned from the
        unlinked state to the free state.  Small file systems are particularly
        vulnerable to these problems, and it can manifest as mainly hangs, but
        also file system corruption.  The patches have been tested for
        literally many weeks, with a very gruelling test, so I have a high
        level of confidence.
      
         - Andreas Gruenbacher wrote a series of five patches for various
           lockups during the transition of inodes from unlinked to free.
      
           The main patch is titled "Fix gfs2_lookup_by_inum lock inversion"
           and the other four are support and cleanup patches related to that.
      
         - Ben Marzinski contributed two patches with regard to a recreatable
           problem when gfs2 tries to write a page to a file that is being
           truncated, resulting in a BUG() in gfs2_remove_from_journal.
      
           Note that Ben had to export vfs function __block_write_full_page to
           get this to work properly.  It's been posted a long time and he
           talked to various VFS people about it, and nobody seemed to mind.
      
         - I contributed 3 patches:
             o The first one fixes a memory corruptor: a race in which one
               process can overwrite the gl_object pointer set by another
               process, causing kernel panic and other symptoms.
             o The second patch fixes another race that resulted in a
               false-positive BUG_ON.  This occurred when resource group
               reservations were freed by one process while another process
               was trying to grab a new reservation in the same resource
               group.
             o The third patch fixes a problem with doing journal replay when
               the journals are not all the same size"
