Merge branch 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux into drm-next

Here's the vblank timestamp pull request you wanted.

I addressed the few bugs that Mario pointed out and added
the r-bs.

As it has been a while since I made the changes, I gave it a
quick spin on a few different i915 machines. Fortunately
everything still seems to be fine.

* 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux:
  drm/i915: Add a kludge for DSL incrementing too late and ISR not working
  drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos()
  drm: Pass 'flags' from the caller to .get_scanout_position()
  drm: Fix vblank timestamping constants for interlaced modes
  drm/i915: Fix scanoutpos calculations for interlaced modes
  drm: Change {pixel,line,frame}dur_ns from s64 to int
  drm: Use crtc_clock in drm_calc_timestamping_constants()
  drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()
  drm: Simplify the math in drm_calc_timestamping_constants()
  drm: Improve drm_calc_timestamping_constants() documentation
  drm/i915: Call drm_calc_timestamping_constants() earlier
  drm/i915: Kill hwmode save/restore
  drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()
  drm: Pass the display mode to drm_calc_timestamping_constants()
