       "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

      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"
