Pull perf updates from Ingo Molnar:
 "The main kernel side changes were:

   - Modernize the kprobe and uprobe creation/destruction tooling ABIs:

     The existing text based APIs (kprobe_events and uprobe_events in
     tracefs), are naive, limited ABIs in that they require user-space
     to clean up after themselves, which is both difficult and fragile
     if the tool is buggy or exits unexpectedly. In other words they are
     not really suited for modern, robust tooling.

     So introduce a modern, file descriptor based ABI that does not have
     these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
     PMUs and extend the perf_event_open() syscall to create events with
     a kprobe/uprobe attached to them. These [k,u]probe are associated
     with this file descriptor, so they are not available in tracefs.

     (Song Liu)

   - Intel Cannon Lake CPU support (Harry Pan)

   - Intel PT cleanups (Alexander Shishkin)

   - Improve the performance of pinned/flexible event groups by using RB
     trees (Alexey Budankov)

   - Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
     of hardware breakpoints, which new ABI variant massively speeds up
     existing tooling that uses hardware breakpoints to instrument (and
     debug) memory usage.

Pull locking updates from Ingo Molnar:
 "The main changes in the locking subsystem in this cycle were:

   - Add the Linux Kernel Memory Consistency Model (LKMM) subsystem,
     which is an an array of tools in tools/memory-model/ that formally
     describe the Linux memory coherency model (a.k.a.
     Documentation/memory-barriers.txt), and also produce 'litmus tests'
     in form of kernel code which can be directly executed and tested.

     Here's a high level background article about an earlier version of
     this work on LWN.net:

        https://lwn.net/Articles/718628/

     The design principles:

      "There is reason to believe that Documentation/memory-barriers.txt
       could use some help, and a major purpose of this patch is to
       provide that help in the form of a design-time tool that can
       produce all valid executions of a small fragment of concurrent
       Linux-kernel code, which is called a "litmus test". This tool's
       functionality is roughly similar to a full state-space search.
       Please note that this is a design-time tool, not useful for
       regression testing. However, we hope that the underlying
       Linux-kernel memory model will be incorporated into other tools
       capable of analyzing large bodies of code for regression-testing
       purposes."

     [...]

      "A second tool is klitmus7, which converts litmus tests to
       loadable kernel modules for direct testing. As with herd7, the
       klitmus7 code is freely available from

         http://diy.inria.fr/sources/index.html

       (and via "git" at https://github.com/herd/herdtools7)"

Two config options in the lock debugging menu that are probably the most
frequently used, as far as I am concerned, is the PROVE_LOCKING and
LOCK_STAT. From a UI perspective, they should be front and center. So
these two options are now moved to the top of the lock debugging menu.

The DEBUG_WW_MUTEX_SLOWPATH option is also added to the PROVE_LOCKING
umbrella.

There are a couples of lock debugging Kconfig options that depends on
the following support options:

 - TRACE_IRQFLAGS_SUPPORT
 - STACKTRACE_SUPPORT
 - LOCKDEP_SUPPORT

That makes those lock debugging options harder to read and understand.
So a new LOCK_DEBUGGING_SUPPORT option is added that is equivalent to
the above three options together. That makes the Kconfig.debug file
more readable.

For a rwsem, locking can either be exclusive or shared. The corresponding
exclusive or shared unlock must be used. Otherwise, the protected data
structures may get corrupted or the lock may be in an inconsistent state.

In order to detect such anomaly, a new configuration option DEBUG_RWSEMS
is added which can be enabled to look for such mismatches and print
warnings that that happens.

Donald reported that IPv6 route leaking between VRFs is not working.
The root cause is the strict argument in the call to rt6_lookup when
validating the nexthop spec.

ip6_route_check_nh validates the gateway and device (if given) of a
route spec. It in turn could call rt6_lookup (e.g., lookup in a given
table did not succeed so it falls back to a full lookup) and if so
sets the strict argument to 1. That means if the egress device is given,
the route lookup needs to return a result with the same device. This
strict requirement does not work with VRFs (IPv4 or IPv6) because the
oif in the flow struct is overridden with the index of the VRF device
to trigger a match on the l3mdev rule and force the lookup to its table.

The right long term solution is to add an l3mdev index to the flow
struct such that the oif is not overridden. That solution will not
backport well, so this patch aims for a simpler solution to relax the
strict argument if the route spec device is an l3mdev slave. As done
in other places, use the FLOWI_FLAG_SKIP_NH_OIF to know that the
RT6_LOOKUP_F_IFACE flag needs to be removed.
