       "Once again, Catalin's off on holiday and I'm looking after the arm64
        tree.  Please can you pull the following arm64 updates for 3.17?
      
        Note that this branch also includes the new GICv3 driver (merged via a
        stable tag from Jason's irqchip tree), since there is a fix for older
        binutils on top.
      
        Changes include:
         - context tracking support (NO_HZ_FULL) which narrowly missed 3.16
         - vDSO layout rework following Andy's work on x86
         - TEXT_OFFSET fuzzing for bootloader testing
         - /proc/cpuinfo tidy-up
         - preliminary work to support 48-bit virtual addresses, but this is
           currently disabled until KVM has been ported to use it (the patches
           do, however, bring some nice clean-up)
         - boot-time CPU sanity checks (especially useful on heterogenous
           systems)
         - support for syscall auditing
         - support for CC_STACKPROTECTOR
         - defconfig updates"

      Pull tracing updates from Steven Rostedt:
       "This pull request has a lot of work done.  The main thing is the
        changes to the ftrace function callback infrastructure.  It's
        introducing a way to allow different functions to call directly
        different trampolines instead of all calling the same "mcount" one.
      
        The only user of this for now is the function graph tracer, which
        always had a different trampoline, but the function tracer trampoline
        was called and did basically nothing, and then the function graph
        tracer trampoline was called.  The difference now, is that the
        function graph tracer trampoline can be called directly if a function
        is only being traced by the function graph trampoline.  If function
        tracing is also happening on the same function, the old way is still
        done.
      
        The accounting for this takes up more memory when function graph
        tracing is activated, as it needs to keep track of which functions it
        uses.  I have a new way that wont take as much memory, but it's not
        ready yet for this merge window, and will have to wait for the next
        one.
      
        Another big change was the removal of the ftrace_start/stop() calls
        that were used by the suspend/resume code that stopped function
        tracing when entering into suspend and resume paths.  The stop of
        ftrace was done because there was some function that would crash the
        system if one called smp_processor_id()! The stop/start was a big
        hammer to solve the issue at the time, which was when ftrace was first
        introduced into Linux.  Now ftrace has better infrastructure to debug
        such issues, and I found the problem function and labeled it with
        "notrace" and function tracing can now safely be activated all the way
        down into the guts of suspend and resume
      
        Other changes include clean ups of uprobe code, clean up of the
        trace_seq() code, and other various small fixes and clean ups to
        ftrace and tracing"

      Pull config-bisect changes from Steven Rostedt:
       "The big change here is the rewrite of config-bisect.  The old way
        never worked properly as it assumed the bad config was a subset of the
        good config, and just found the config that would break the build.
      
        The new way does a diff of the bad config verses the good config and
        makes the similar until it finds that one config works and the other
        does not and reports the config that makes that difference.  The two
        configs do not need to be related.  It is much more useful now:

      Pull clock framework updates from Mike Turquette:
       "The clock framework changes for 3.17 are mostly additions of new clock
        drivers and fixes/enhancements to existing clock drivers.  There are
        also some non-critical fixes and improvements to the framework core.
      
        Changes to the clock framework core include:
         - improvements to printks on errors
         - flattening the previously hierarchal structure of per-clock entries
           in debugfs
         - allow per-clock debugfs entries that are specific to a particular
           clock driver
         - configure initial clock parent and/or initial clock rate from
           Device Tree
         - several feature enhancements to the composite clock type
         - misc fixes
      
        New clock drivers added include:
         - TI Palmas PMIC
         - Allwinner A23 SoC
         - Qualcomm APQ8084 and IPQ8064 SoCs
         - Rockchip rk3188, rk3066 and rk3288 SoCs
         - STMicroelectronics STiH407 SoC
         - Cirrus Logic CLPS711X SoC
      
        Many fixes, feature enhancements and further clock tree support for
        existing clock drivers also were merged, such as Samsung's "ARMCLK
        down" power saving feature for their Exynos4 & Exynos5 SoCs"

      Pull cgroup changes from Tejun Heo:
       "Mostly changes to get the v2 interface ready.  The core features are
        mostly ready now and I think it's reasonable to expect to drop the
        devel mask in one or two devel cycles at least for a subset of
        controllers.
      
         - cgroup added a controller dependency mechanism so that block cgroup
           can depend on memory cgroup.  This will be used to finally support
           IO provisioning on the writeback traffic, which is currently being
           implemented.
      
         - The v2 interface now uses a separate table so that the interface
           files for the new interface are explicitly declared in one place.
           Each controller will explicitly review and add the files for the
           new interface.
      
         - cpuset is getting ready for the hierarchical behavior which is in
           the similar style with other controllers so that an ancestor's
           configuration change doesn't change the descendants' configurations
           irreversibly and processes aren't silently migrated when a CPU or
           node goes down.
