      Pull ARM SoC defconfig updates from Olof Johansson:
       "Defconfig updates are kept separate from other branches mostly to
        avoid conflicts between the different categories (driver branch
        enabling something that has context conflict with SoC options, etc).
      
        A lot of this again is scattered across the various hardware
        platforms.  multi_v7_defconfig, our "generic" config for most 32-bit
        platforms has been gone through by Marvell Berlin maintainers and
        added most options they need to run on their hardware.  Broadcom NSP
        is also added there, and the new Atmel SAMA5D2 (added last release).
        Rockchip also has display and other devices supported in that config.
      
        In addition to that, the usual small churn of new options being added
        here and there"

      Pull ARM SoC driver updates from Olof Johansson:
       "As we've enabled multiplatform kernels on ARM, and greatly done away
        with the contents under arch/arm/mach-*, there's still need for
        SoC-related drivers to go somewhere.
      
        Many of them go in through other driver trees, but we still have
        drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code
        that might be shared between ARM and ARM64 (or just in general makes
        sense to not have under the architecture directory).
      
        This branch contains mostly such code:
      
         - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
           communicate with power management blocks on these SoCs for use by
           clock, regulator and bus frequency drivers.
      
         - Allwinner Reduced Serial Bus driver, again used to communicate with
           PMICs.
      
         - Drivers for ARM's SCPI (System Control Processor).  Not to be
           confused with PSCI (Power State Coordination Interface).  SCPI is
           used to communicate with the assistant embedded cores doing power
           management, and we have yet to see how many of them will implement
           this for their hardware vs abstracting in other ways (or not at all
           like in the past).
      
         - To make confusion between SCPI and PSCI more likely, this release
           also includes an update of PSCI to interface version 1.0.
      
         - Rockchip support for power domains.
      
         - A driver to talk to the firmware on Raspberry Pi"

      Fix alloc_node_mem_map() to work on ia64 again · b0aeba74
      Tony Luck authored
      In commit a1c34a3b ("mm: Don't offset memmap for flatmem") Laura
      fixed a problem for Srinivas relating to the bottom 2MB of RAM on an ARM
      IFC6410 board.
      
      One small wrinkle on ia64 is that it allocates the node_mem_map earlier
      in arch code, so it skips the block of code where "offset" is
      initialized.
      
      Move initialization of start and offset before the check for the
      node_mem_map so that they will always be available in the latter part of
      the function.

      Revert "bridge: Allow forward delay to be cfgd when STP enabled" · 8a921265
      Vlad Yasevich authored
      This reverts commit 34c2d9fb.
      
      There are 2 reasons for this revert:
       1)  The commit in question doesn't do what it says it does.  The
           description reads: "Allow bridge forward delay to be configured
           when Spanning Tree is enabled."  This was already the case before
           the commit was made.  What the commit actually do was disallow
           invalid values or 'forward_delay' when STP was turned off.
      
       2)  The above change was actually a change in the user observed
           behavior and broke things like libvirt and other network configs
           that set 'forward_delay' to 0 without enabling STP.  The value
           of 0 is actually used when STP is turned off to immediately mark
           the bridge as forwarding.

      bpf_trace: Make dependent on PERF_EVENTS · a31d82d8
      Steven Rostedt authored
      Arnd Bergmann reported:
      
        In my ARM randconfig tests, I'm getting a build error for
        newly added code in bpf_perf_event_read and bpf_perf_event_output
        whenever CONFIG_PERF_EVENTS is disabled:
      
        kernel/trace/bpf_trace.c: In function 'bpf_perf_event_read':
        kernel/trace/bpf_trace.c:203:11: error: 'struct perf_event' has no member named 'oncpu'
        if (event->oncpu != smp_processor_id() ||
                 ^
        kernel/trace/bpf_trace.c:204:11: error: 'struct perf_event' has no member named 'pmu'
              event->pmu->count)
      
        This can happen when UPROBE_EVENT is enabled but KPROBE_EVENT
        is disabled. I'm not sure if that is a configuration we care
        about, otherwise we could prevent this case from occuring by
        adding Kconfig dependencies.
      
      Looking at this further, it's really that UPROBE_EVENT enables PERF_EVENTS.
      By just having BPF_EVENTS depend on PERF_EVENTS, then all is fine.
