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).

drm: Clarify vblank ts/scanoutpos sampling #defines

One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

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

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().

It is hardly possible to review the drmP.h includes, anymore. Order them
alphabetically, linux/ first, then asm/ and then local drm/ includes.
Since a long time ago, kernel headers have been converted to include
required headers themselves. No-one cares whether that means the compiler
has to include a header multiple times. In fact, GCC already does some
optimization regarding multiple inclusions if a sorrounding #ifndef is
present.
