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 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

  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().

closer to being able to build allyesconfig or allmodconfig,
and it enables the Debian default generic config to build.

Currently vga_switcheroo_unregister_handler is called unconditionally when

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.

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.

We never turn this on, no point maintaining the code for it..

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.
