          adjustments in the drivers that use it.  The individual drivers
          aren't fixed by this commit, but will be dealt with using follow-on
          commits.  From Eric Dumazet.

      Pull "remoteproc/rpmsg: new subsystem" from Arnd Bergmann:
       "This new subsystem provides a common way to talk to secondary
        processors on an SoC, e.g.  a DSP, GPU or service processor, using
        virtio as the transport.  In the long run, it should replace a few
        dozen vendor specific ways to do the same thing, which all never made
        it into the upstream kernel.  There is a broad agreement that rpmsg is
        the way to go here and several vendors have started working on
        replacing their own subsystems.
      
        Two branches each add one virtio protocol number.  Fortunately the
        numbers were agreed upon in advance, so there are only context
        changes.

      net: fix a potential rcu_read_lock() imbalance in rt6_fill_node() · 94f826b8
      Eric Dumazet authored
      Commit f2c31e32 (net: fix NULL dereferences in check_peer_redir() )
      added a regression in rt6_fill_node(), leading to rcu_read_lock()
      imbalance.
      
      Thats because NLA_PUT() can make a jump to nla_put_failure label.
      
      Fix this by using nla_put()
      
      Many thanks to Ben Greear for his help

      Fix potential endless loop in kswapd when compaction is not enabled · 496b919b
      Rik van Riel authored
      We should only test compaction_suitable if the kernel is built with
      CONFIG_COMPACTION, otherwise the stub compaction_suitable function will
      always return COMPACT_SKIPPED and send kswapd into an infinite loop.

        and yet there is no reason for most of these guys to care about the
        sub fields within the device struct.  This allows us to significantly
        reduce the scope of headers including headers.  For this instance, a
        reduction of about 40% is achieved by replacing the include with the
        simple fact that the device is some kind of a struct.
      
        Unlike the much larger module.h cleanup, this one is simply two
        commits.  One to fix the implicit <linux/device.h> users, and then one
        to delete the device.h includes from the linux/include/ dir wherever

      Pull <linux/bug.h> cleanup from Paul Gortmaker:
       "The changes shown here are to unify linux's BUG support under the one
        <linux/bug.h> file.  Due to historical reasons, we have some BUG code
        in bug.h and some in kernel.h -- i.e.  the support for BUILD_BUG in
        linux/kernel.h predates the addition of linux/bug.h, but old code in
        kernel.h wasn't moved to bug.h at that time.  As a band-aid, kernel.h
        was including <asm/bug.h> to pseudo link them.
      
        This has caused confusion[1] and general yuck/WTF[2] reactions.  Here
        is an example that violates the principle of least surprise:
      
            CC      lib/string.o
            lib/string.c: In function 'strlcat':
            lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
            make[2]: *** [lib/string.o] Error 1
            $
            $ grep linux/bug.h lib/string.c
            #include <linux/bug.h>
            $
      
        We've included <linux/bug.h> for the BUG infrastructure and yet we
        still get a compile fail! [We've not kernel.h for BUILD_BUG_ON.] Ugh -
        very confusing for someone who is new to kernel development.
      
        With the above in mind, the goals of this changeset are:
      
        1) find and fix any include/*.h files that were relying on the
           implicit presence of BUG code.
        2) find and fix any C files that were consuming kernel.h and hence
           relying on implicitly getting some/all BUG code.
        3) Move the BUG related code living in kernel.h to <linux/bug.h>
        4) remove the asm/bug.h from kernel.h to finally break the chain.
      
        During development, the order was more like 3-4, build-test, 1-2.  But
        to ensure that git history for bisect doesn't get needless build
        failures introduced, the commits have been reorderd to fix the problem
        areas in advance.

      xen/acpi: Fix Kconfig dependency on CPU_FREQ · df7a3ee2
      Konrad Rzeszutek Wilk authored
      The functions: "acpi_processor_*" sound like they depend on CONFIG_ACPI_PROCESSOR
      but in reality they are exposed when CONFIG_CPU_FREQ=[y|m]. As such
      update the Kconfig to have this dependency and fix compile issues:
