Merge tag 'topic/drm-misc-2015-10-19' of git://anongit.freedesktop.org/drm-intel into drm-next
More drm-misc for 4.4.
- fb refcount fix in atomic fbdev
- various locking reworks to reduce drm_global_mutex and dev->struct_mutex
- rename docbook to gpu.tmpl and include vga_switcheroo stuff, plus more
vga_switcheroo (Lukas Wunner)
- viewport check fixes for atomic drivers from Ville
- DRM_DEBUG_VBL from Ville
- non-contentious header fixes from Mikko Rapeli
- small things all over
