Merge tag 'topic/drm-header-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel into drm-next

So here's the header cleanup, rebased on top of drm-next. Two new header
files are created here:

- drivers/gpu/drm/drm_internal.h for non-legacy drm.ko private
  declarations.

- include/drm/drm_legacy.h for legacy interfaces used by non-kms drivers.

And of course lots fo stuff gets shuffled into the already existing
drivers/gpu/drm/drm_legacy.h for drm.ko internal stuff.

topic branch smoke-tested in drm-intel-nightly for a bit. And the 0day
tester also worked through it (and found a few places I didn't add a
static to functions).

So updated vblank-rework pull request, now with the polish that Mario
requested applied (and reviewed by him). Also with backmerge like you've
requested for easier merging.

The neat thing this finally allows is to immediately disable the vblank
interrupt on the last drm_vblank_put if the hardware has perfectly
accurate vblank counter and timestamp readout support. On i915 that
required piles of small adjustements from Ville since depending upon the
platform and port the vblank happens at different scanout lines.

Of course this is fully opt-in and per-device (we need that since gen2
doesn't have a hw vblank counter).

* tag 'topic/vblank-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel: (22 commits)
  drm: Clarify vblank ts/scanoutpos sampling #defines

This fixes problems on ppc64 platforms, where we could end up using

use cached memory.

The userspace drm.h include doesn't prefix the drm directory.  This can lead
to compile failures as /usr/include/drm/ isn't in the standard gcc include
paths.  Fix it to be <drm/drm.h>, which matches the rest of the driver drm
header files that get installed into /usr/include/drm.

I've read INVBL as "invalid backlight" and got mightly confused.
The #defines are already fairly long and we can afford to extend
them a bit more without resulting in ugly code all over.

I'm not sure how useful the complicated bitmask return value of these
functions really are since no one checks them. But for now let's keep
things as is.

Imo u32 hints at a register value, but in reality all callers only
care whether the sampled timestamp is precise or not. So give them
just a bool.

Drivers without a hardware vblank counter simply can't account for the
vblanks that happened while the vblank interrupt was off. To check
this grab a vblank timestamp and if the result is dubious follow the
normal save-and-disable logic.

Drivers should prevent this by setting vblank_disable_allowed = false,
but since running vblank interrupts constantly is not good for power
consumption most drivers lie. Testing for precise vblank timestamps is
the next best thing we can check for.

With the new support for immediate vblank disabling we always disabled
the vblank interrupt right away, irrespective of the vblank offdelay
setting.

But being able to let vblanks run forever is fairly useful for
debugging, so restore that behaviour.
