Merge remote branch 'nouveau/for-airlied' of nouveau-2.6
* 'nouveau/for-airlied' of /home/airlied/kernel/drm-next: nouveau: fix state detection with switchable graphics drm/nouveau: move dereferences after null checks drm/nv50: make the pgraph irq handler loop like the pre-nv50 version drm/nv50: delete ramfc object after disabling fifo, not before drm/nv50: avoid unloading pgraph context when ctxprog is running drm/nv50: align size of buffer object to the right boundaries. drm/nv50: disregard dac outputs in nv50_sor_dpms() drm/nv50: prevent multiple init tables being parsed at the same time drm/nouveau: make dp auxch xfer len check for reads only drm/nv40: make INIT_COMPUTE_MEM a NOP, just like nv50 drm/nouveau: Add proper vgaarb support. drm/nouveau: Fix fbcon on mixed pre-NV50 + NV50 multicard. drivers/gpu/drm/nouveau/nouveau_grctx.c: correct NULL test drm/nouveau: call ttm_bo_wait with the bo lock held to prevent hang drm/nouveau: Fixup semaphores on pre-nv50 cards. drm/nouveau: Add getparam to get available PGRAPH units. drm/nouveau: Add module options to disable acceleration. drm/nouveau: fix non-vram notifier blocks
