Merge tag 'v3.6-rc2' into drm-intel-next
Backmerge Linux 3.6-rc2 to resolve a few funny conflicts before we put even more madness on top: - drivers/gpu/drm/i915/i915_irq.c: Just a spurious WARN removed in -fixes, that has been changed in a variable-rename in -next, too. - drivers/gpu/drm/i915/intel_ringbuffer.c: -next remove scratch_addr (since all their users have been extracted in another fucntion), -fixes added another user for a hw workaroudn.
