       - Fix mismatch between DMA mapping direction (was wrong) and DMA
         synchronization direction (was correct) of isochronous reception
         buffers of userspace drivers if vma-mapped for R/W access.  For
         example, libdc1394 was affected.
      
       - more consistent retry stategy in device discovery/ rediscovery, and
         improved failure diagnostics

      Pull main drm updates from Dave Airlie:
       "This is the main merge window request for the drm.
      
        It's big, but jam packed will lots of features and of course 0
        regressions.  (okay maybe there'll be one).
      
        Highlights:
      
         - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
           (qemu only).  These drivers use the generic modesetting drivers.
      
         - initial prime/dma-buf support for i915, nouveau, radeon, udl and
           exynos
      
         - switcheroo audio support: so GPUs with HDMI can turn off the sound
           driver without crashing stuff.
      
         - There are some patches drifting outside drivers/gpu into x86 and
           EFI for better handling of multiple video adapters in Apple Macs,
           they've got correct acks except one trivial fixup.
      
         - Core:
      	edid parser has better DMT and reduced blanking support,
      	crtc properties,
      	plane properties,
      
         - Drivers:
      	exynos: add 2D core accel support, prime support, hdmi features
      	intel: more Haswell support, initial Valleyview support, more
      	    hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
      	    cleanups and fixes
      	radeon: more HDMI audio support, improved GPU lockup recovery
      	    support, remove nested mutexes, less memory copying on PCIE, fix
      	    bus master enable race (kexec), improved fence handling
      	gma500: cleanups, 1080p support, acpi fixes
      	nouveau: better nva3 memory reclocking, kepler accel (needs
      	    external firmware rip), async buffer moves on nv84+ hw.
      
        I've some more dma-buf patches that rely on the dma-buf merge for vmap
        stuff, and I've a few fixes building up, but I'd decided I'd better
        get rid of the main pull sooner rather than later, so the audio guys
        are also unblocked."

      Pull more networking updates from David Miller:
       "Ok, everything from here on out will be bug fixes."
      
      1) One final sync of wireless and bluetooth stuff from John Linville.
         These changes have all been in his tree for more than a week, and
         therefore have had the necessary -next exposure.  John was just away
         on a trip and didn't have a change to send the pull request until a
         day or two ago.
      
      2) Put back some defines in user exposed header file areas that were
         removed during the tokenring purge.  From Stephen Hemminger and Paul
         Gortmaker.
      
      3) A bug fix for UDP hash table allocation got lost in the pile due to
         one of those "you got it..  no I've got it.." situations.  :-)
      
         From Tim Bird.
      
      4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
         try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.
      
      5) RCU routing table lookups can race with free_fib_info(), causing
         crashes when we deref the device pointers in the route.  Fix by
         releasing the net device in the RCU callback.  From Yanmin Zhang.

      Merge branch 'perf-uprobes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · 654443e2
      Linus Torvalds authored
      Pull user-space probe instrumentation from Ingo Molnar:
       "The uprobes code originates from SystemTap and has been used for years
        in Fedora and RHEL kernels.  This version is much rewritten, reviews
        from PeterZ, Oleg and myself shaped the end result.
      
        This tree includes uprobes support in 'perf probe' - but SystemTap
        (and other tools) can take advantage of user probe points as well.
      
        Sample usage of uprobes via perf, for example to profile malloc()
        calls without modifying user-space binaries.
      
        First boot a new kernel with CONFIG_UPROBE_EVENT=y enabled.
      
        If you don't know which function you want to probe you can pick one
        from 'perf top' or can get a list all functions that can be probed
        within libc (binaries can be specified as well):
      
      	$ perf probe -F -x /lib/libc.so.6
      
        To probe libc's malloc():
      
      	$ perf probe -x /lib64/libc.so.6 malloc
      	Added new event:
      	probe_libc:malloc    (on 0x7eac0)
      
        You can now use it in all perf tools, such as:
      
      	perf record -e probe_libc:malloc -aR sleep 1
      
        Make use of it to create a call graph (as the flat profile is going to
        look very boring):
      
      	$ perf record -e probe_libc:malloc -gR make
      	[ perf record: Woken up 173 times to write data ]
      	[ perf record: Captured and wrote 44.190 MB perf.data (~1930712
      
      	$ perf report | less

        The core uprobes design is fairly straightforward: uprobes probe
        points register themselves at (inode:offset) addresses of
        libraries/binaries, after which all existing (or new) vmas that map
        that address will have a software breakpoint injected at that address.
        vmas are COW-ed to preserve original content.  The probe points are
        kept in an rbtree.
      
        If user-space executes the probed inode:offset instruction address
        then an event is generated which can be recovered from the regular
        perf event channels and mmap-ed ring-buffer.
      
        Multiple probes at the same address are supported, they create a
        dynamic callback list of event consumers.
      
        The basic model is further complicated by the XOL speedup: the
        original instruction that is probed is copied (in an architecture
        specific fashion) and executed out of line when the probe triggers.
        The XOL area is a single vma per process, with a fixed number of
        entries (which limits probe execution parallelism).
      
        The API: uprobes are installed/removed via
        /sys/kernel/debug/tracing/uprobe_events, the API is integrated to
        align with the kprobes interface as much as possible, but is separate
        to it.
      
        Injecting a probe point is privileged operation, which can be relaxed
        by setting perf_paranoid to -1.
      
        You can use multiple probes as well and mix them with kprobes and
        regular PMU events or tracepoints, when instrumenting a task."
      
      Fix up trivial conflicts in mm/memory.c due to previous cleanup of
      unmap_single_vma().

      unsigned shorts, not chars. Treating them otherwise produces corrupted

      drm/nouveau: Check dsm on switcheroo unregister · 2f3787aa
      Andreas Heider authored
      Currently vga_switcheroo_unregister_handler is called unconditionally when
      nouveau is unloaded, even when nouveau never registered a handler. This
      interferes with other switcheroo handlers, as vga_switcheroo doesn't check who
      called unregister_handler, but simply unregisters the current handler. This
      patch adds a check so unregister is only called if a handler was registered by
      nouveau before.

      drm/nouveau/fifo: turn all fifo modules into engine modules · c420b2dc
      Ben Skeggs authored
      Been tested on each major revision that's relevant here, but I'm sure there
      are still bugs waiting to be ironed out.
      
      This is a *very* invasive change.
      
      There's a couple of pieces left that I don't like much (eg. other engines
      using fifo_priv for the channel count), but that's an artefact of there
      being a master channel list still.  This is changing, slowly.

      drm/nouveau/fifo: remove all the "special" engine hooks · 67b342ef
      Ben Skeggs authored
      All the places this stuff is actually needed tends to be chipset-specific
      anyway, so we're able to just inline the register bashing instead.
      
      The parts of the common code that still directly touch PFIFO temporarily
      have conditionals, these will be removed in subsequent commits that will
      refactor the fifo modules into engine modules like graph/mpeg etc.
