Introduce accessors for TTM buffer object memory that has been mapped into the kernel virtual address space or as IO memory. IO memory needs to be accessed via special accessor functions, not by dereferencing the iomem cookie. The wrappers hide the details of 32-bit access and honour the TTM map type. nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is received from

Revised patch set v2. [PATCH 1/8] drm/nouveau: bo read/write wrappers for nv04_crtc.c [PATCH 2/8] drm/nouveau: use bo accessors for push buffers [PATCH 3/8] drm/nouveau: OUT_RINGp - optimize OUT_RING loops [PATCH 4/8] drm/nv50: proper notifier_bo access in nv50_display_vblank_crtc_handler() [PATCH 5/8] drm/nouveau: access fbcon notifier via bo accessors [PATCH 6/8] drm/nouveau: screen_base and
