Backmerge Linus tree after rc5 + drm-fixes went in.

and Ben requested this for nouveau also.

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.
The HLCDC block provides a single RGB output port, and only supports LCD
panels connection to LCD panels for now.
The atmel,panel property link the HLCDC RGB output with the LCD panel
connected on this port (note that the HLCDC RGB connector implementation
makes use of the DRM panel framework).
Connection to other external devices (DRM bridges) might be added later by
mean of a new atmel,xxx (atmel,bridge) property.

Next batch of atomic work. Most important is the propertification from Rob
and the nth iteration of the actual atomic ioctl originally from Ville.
Big differences compared to earlier revisions:
- Core properties are now fully handled by the core, drivers can only
handle driver-specific properties.
- Atomic props&ioctl are opt-in per file_priv, userspace needs to
explicitly ask for it (like universal plane support).
- For now all hidden behind the atomic module option until this has
settled a bit.
- Atomic modesets are currently not possible since the exact abi for how
to handle the mode property is still under discussion.
Besides this some cleanup patches from me and the addition of per-object
state to global state backpointers to simplify drivers.

Once a driver is using atomic helpers for modeset, the next step is to
switch over to atomic properties. To do this, make sure that any
modeset objects have their ->atomic_{get,set}_property() vfuncs suitably
populated if they have custom properties (you did already remember to
plug in atomic-helper func for the legacy ->set_property() vfuncs,
right?), and then set DRIVER_ATOMIC bit in driver_features flag.
A new cap is introduced, DRM_CLIENT_CAP_ATOMIC, for the purposes of
shielding legacy userspace from atomic properties. Mostly for the
benefit of legacy DDX drivers that do silly things like getting/setting
each property at startup (since some of the new atomic properties will
be able to trigger modeset).

The DU uses the module functional clock as the default pixel clock, but
supports using an externally supplied pixel clock instead. Support this
by adding the external pixel clock to the DT bindings, and selecting the
clock automatically at runtime based on the requested mode pixel
frequency.
The input clock pins to DU channels routing is configurable, but
currently hardcoded to connect input clock i to channel i.

The highlight is the series that reworks the idle management on powernv, which
allows us to use deeper idle states on those machines.
There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem.
An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we
take it through the powerpc tree.
A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit
maintainers.
A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file,
so that tools can use it.
Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and
the patch to add __force to get_user() so we can use bitwise types.

For x86:
- small performance improvements (though only on weird guests)
- usual round of hardware-compliancy fixes from Nadav
- APICv fixes
- XSAVES support for hosts and guests. XSAVES hosts were broken because
the (non-KVM) XSAVES patches inadvertently changed the KVM userspace
ABI whenever XSAVES was enabled; hence, this part is going to stable.
Guest support is just a matter of exposing the feature and CPUID leaves
support.
Right now KVM is broken for PPC BookE in your tree (doesn't compile).

as I thought it might be. I'm pushing this in now.
This will allow Thomas to debug his irq work for 3.20.
This adds two new features:
1) Allow traceopoints to be enabled right after mm_init(). By passing
in the trace_event= kernel command line parameter, tracepoints can be
enabled at boot up. For debugging things like the initialization of
interrupts, it is needed to have tracepoints enabled very early. People
have asked about this before and this has been on my todo list. As it
can be helpful for Thomas to debug his upcoming 3.20 IRQ work, I'm
pushing this now. This way he can add tracepoints into the IRQ set up
and have users enable them when things go wrong.
2) Have the tracepoints printed via printk() (the console) when they
are triggered. If the irq code locks up or reboots the box, having the
tracepoint output go into the kernel ring buffer is useless for
debugging. But being able to add the tp_printk kernel command line
option along with the trace_event= option will have these tracepoints
printed as they occur, and that can be really useful for debugging
early lock up or reboot problems.
This code is not that intrusive and it passed all my tests. Thomas tried
them out too and it works for his needs.

tracing: Add tp_printk cmdline to have tracepoints go to printk()
tracing: Move enabling tracepoints to just after rcu_init()
This adds a small module for managing a pool of batch buffers.
The only current use case is for the command parser, as described
in the kerneldoc in the patch. The code is simple, but separating
it out makes it easier to change the underlying algorithms and to
extend to future use cases should they arise.
The interface is simple: init to create an empty pool, fini to
clean it up, get to obtain a new buffer. Note that all buffers are
expected to be inactive before cleaning up the pool.
Locking is currently based on the caller holding the struct_mutex.
We already do that in the places where we will use the batch pool
for the command parser.
v2:
- s/BUG_ON/WARN_ON/ for locking assertions
- Remove the cap on pool size
- Switch from alloc/free to init/fini
v3:
- Idiomatic looping structure in _fini
- Correct handling of purged objects
- Don't return a buffer that's too much larger than needed
v4:
- Rebased to latest -nightly
v5:
- Remove _put() function and clean up comments to match
v6:
- Move purged check inside the loop (danvet, from v4 1/7 feedback)
v7:
- Use single list instead of two. (Chris W)
- s/active_list/cache_list
- Squashed in debug patches (Chris W)
drm/i915: Add a batch pool debugfs file
It provides some useful information about the buffers in
the global command parser batch pool.
v2: rebase on global pool instead of per-ring pools
v3: rebase
drm/i915: Add batch pool details to i915_gem_objects debugfs
To better account for the potentially large memory consumption
of the batch pool.
v8:
- Keep cache in LRU order (danvet, from v6 1/5 feedback)
