Pull drm updates from Dave Airlie:
"This is the main git pull for the drm,
I pretty much froze major pulls at -rc5/6 time, and haven't had much
fallout, so will probably continue doing that.
Lots of changes all over, big internal header cleanup to make it clear
drm features are legacy things and what are things that modern KMS
drivers should be using. Also big move to use the new generic fences
in all the TTM drivers.
core:
atomic prep work,
vblank rework changes, allows immediate vblank disables
major header reworking and cleanups to better delinate legacy
interfaces from what KMS drivers should be using.
cursor planes locking fixes

DRM_DEBUG_CODE is currently always set, so distributions enable it. The
only reason to keep support in code is if developers wanted to disable
debug support. Sounds unlikely.
All the DRM_DEBUG() printks are still guarded by a drm_debug read. So if
its cacheline is read once, they're discarded pretty fast.. There should
hardly be any performance penalty, it's even guarded by unlikely().

Changes since v1:
- Kill the sw interrupt dance, add and use
radeon_irq_kms_sw_irq_get_delayed instead.
- Change custom wait function, lockdep complained about it.
Holding exclusive_lock in the wait function might cause deadlocks.
Instead do all the processing in .enable_signaling, and wait
on the global fence_queue to pick up gpu resets.
- Process all fences in radeon_gpu_reset after reset to close a race
with the trylock in enable_signaling.
Changes since v2:
- Small changes to work with the rewritten lockup recovery patches.
Changes since v3:
- Call radeon_fence_schedule_check when exclusive_lock cannot be
acquired to always cause a wake up.
- Reset irqs from hangup check.
- Drop reading seqno in the callback, use cached value.
- Fix indentation in radeon_fence_default_wait
- Add a radeon_test_signaled function, drop a few test_bit calls.
- Make to_radeon_fence global.

This patch adds an IOCTL for turning a pointer supplied by
userspace into a buffer object.
It imposes several restrictions upon the memory being mapped:
1. It must be page aligned (both start/end addresses, i.e ptr and size).
2. It must be normal system memory, not a pointer into another map of IO
space (e.g. it must not be a GTT mmapping of another object).
3. The BO is mapped into GTT, so the maximum amount of memory mapped at
all times is still the GTT limit.
4. The BO is only mapped readonly for now, so no write support.
5. List of backing pages is only acquired once, so they represent a
snapshot of the first use.
Exporting and sharing as well as mapping of buffer objects created by
this function is forbidden and results in an -EPERM.
v2: squash all previous changes into first public version
v3: fix tabs, map readonly, don't use MM callback any more
v4: set TTM_PAGE_FLAG_SG so that TTM never messes with the pages,
pin/unpin pages on bind/unbind instead of populate/unpopulate
v5: rebased on 3.17-wip, IOCTL renamed to userptr, reject any unknown
flags, better handle READONLY flag, improve permission check
v6: fix ptr cast warning, use set_page_dirty/mark_page_accessed on unpin
v7: add warning about it's availability in the API definition
v8: drop access_ok check, fix VM mapping bits

Skip the "manual" pageflip completion checks via polling and
guessing in the vblank handler radeon_crtc_handle_vblank() on
asics which are known to reliably support hw pageflip completion
irqs. Those pflip irqs are a more reliable and race-free method
of handling pageflip completion detection, whereas the "classic"
polling method has some small races in combination with dpm on,
and with the reworked pageflip implementation since Linux 3.16.
On old asics without pflip irqs, the classic method is used.
On asics with known good pflip irqs, only pflip irqs are used
by default, but a new module parameter "use_pflipirqs" allows to
override this in case we encounter asics in the wild with
unreliable or faulty pflip irqs. A module parameter of 0 allows
to use the classic method only in such a case. A parameter of 1
allows to use both classic method and pflip irqs as additional
band-aid to avoid some small races which could happen with the
classic method alone. The setting 1 gives Linux 3.16 behaviour.
Hw pflip irqs are available since R600.
Tested on DCE-4, AMD Cedar - FirePro 2270.
v2: agd5f: only enable pflip interrupts on DCE4+ as they are not
reliable on older asics.

safe:
* For userspace to stream data from CPU to GPU via VRAM instead of GTT

This was originally un-inlined by Andi Kleen in 2011 citing size concerns.
Indeed, a first attempt at inlining it grew radeon.ko by 7%.
However, 2% of cpu is spent in this function. Simply inlining it gave 1% more fps
in Urban Terror.
v2: We know the minimum MMIO size. Adding it to the if allows the compiler to
optimize the branch out, improving both performance and size.
The v2 patch decreases radeon.ko size by 2%. I didn't re-benchmark, but common sense
says perf is now more than 1% better.
v3: Also change _wreg, make the threshold a define.
Inlining _wreg increased the size a bit compared to v2, so now radeon.ko
is only 1% smaller.

As well as enabling the vblank interrupt. These shouldn't take any
significant amount of time, but at least pinning the BO has actually been
seen to fail in practice before, in which case we need to let userspace
know about it.

Some monitors seem to have problems with deep color enabled, even
though they claim to support it. I'm not sure if the monitor
need a quirk or if the driver is doing something the monitor doesn't
like. At this point lets just disable deep color by default like
we did for hdmi audio and work through the bugs so we can eventually
enable it by default.
