      Pull cgroup fix from Tejun Heo:
       "The recent migration code updates assumed that migrations always
        execute from the top to the bottom once and didn't clean up internal
        states after each migration round; however, cgroup_transfer_tasks()
        repeats the inner steps multiple times and the garbage internal states
        from the previous iteration led to OOPS.
      
        Waiman fixed the bug by reinitializing the relevant states at the end
        of each migration round"

       "Rather important fixes this time.
      
         - The new percpu area allocator had a subtle bug in how it iterates
           the memory regions and could skip viable areas, which led to
           allocation failures for module static percpu variables. Dennis
           fixed the bug and another non-critical one in stat calculation.
      
         - Mark noticed that the generic implementations of percpu local
           atomic reads aren't properly protected against irqs and there's a
           (slim) chance for split reads on some 32bit systems. Generic
           implementations are updated to disable irq when read size is larger
           than ulong size. This may have made some 32bit archs which can do
           atomic local 64bit accesses generate sub-optimal code. We need to
           find them out and implement arch-specific overrides"

        There's a bunch of stuff in here based on the great work Andrey
        Konovalov is doing in fuzzing the USB stack. Lots of bug fixes when
        dealing with corrupted USB descriptors that we've never seen in
        "normal" operation, but is now ensuring the stack is much more
        hardened overall.
      
        There's also the usual XHCI and gadget driver fixes as well, and a
        build error fix, and a few other minor things, full details in the

       "Here are a few small fixes for 4.14-rc4.
      
        The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
        straggler made it in through some other tree (odds are, one of
        mine...) So there's a simple removal of the last user, and then
        finally the macro is removed from the tree.
      
        There's a fix for old crazy udev instances that insist on reloading a
        module when it is removed from the kernel due to the new uevents for
        bind/unbind. This fixes the reported regression, hopefully some year
        in the future we can drop the workaround, once users update to the
        latest version, but I'm not holding my breath.
      
        And then there's a build fix for a linker warning, and a buffer
        overflow fix to match the PCI fixes you took through the PCI tree in
        the same area.

      ahci: don't ignore result code of ahci_reset_controller() · d312fefe

      where an obvious hardware level failure results in an unnecessary 15 second
      delay and a subsequent crash.
      
      So record the result code of ahci_reset_controller() and relay it, rather
      than ignoring it.

      Pull timer fixes from Thomas Gleixner:
       "This adds a new timer wheel function which is required for the
        conversion of the timer callback function from the 'unsigned long
        data' argument to 'struct timer_list *timer'. This conversion has two
        benefits:
      
         1) It makes struct timer_list smaller
      
         2) Many callers hand in a pointer to the timer or to the structure
            containing the timer, which happens via type casting both at setup
            and in the callback. This change gets rid of the typecasts.
      
        Once the conversion is complete, which is planned for 4.15, the old
        setup function and the intermediate typecast in the new setup function
        go away along with the data field in struct timer_list.
      
        Merging this now into mainline allows a smooth queueing of the actual
        conversion in the affected maintainer trees without creating
        dependencies"

      Pull scheduler fixes from Thomas Gleixner:
       "The scheduler pull request comes with the following updates:
      
         - Prevent a divide by zero issue by validating the input value of
           sysctl_sched_time_avg
      
         - Make task state printing consistent all over the place and have
           explicit state characters for IDLE and PARKED so they wont be
           displayed as 'D' state which confuses tools"
