Merge branch 'drm-nouveau-next' of git://git.freedesktop.org/git/nouveau/linux-2.6 into drm-next
* 'drm-nouveau-next' of git://git.freedesktop.org/git/nouveau/linux-2.6: (353 commits) drm/nouveau: remove allocations from gart populate() hook drm/nvc0/fb: slightly improve PMFB intr handling, move out of nvc0_graph.c drm/nvc0/fifo: avoid touching missing subfifos drm/nvd9/disp: bail out of mode_set_base if no fb bound to crtc drm/nvd9/disp: stub some more api hooks so we don't oops on resume drm/nouveau: fix printk typo in ioremap failure path drm/nvc0/pm: minor clock readback fixes drm/nv40/pm: execute memory reset script from vbios drm/nv50/gr: refactor initialisation drm/nouveau: if requested, try harder at disabling sysmem pushbufs drm/nv50/gr: enable ctxprog xfer only when we need it to save power drm/nouveau/dp: add support for displayport table 0x30 drm/nouveau/dp: return master dp table pointer too when looking up encoder drm/nouveau/bios: simplify U/d table hash matching func to just match drm/nouveau/dp: preserve non-pattern bits in DP_TRAINING_PATTERN_SET drm/nvc0/gr: remove MODULE_FIRMWARE() lines drm/nouveau/dp: use alternate lane mask for nvaf drm/nouveau/dp: link rate scripts are selected with a comparison table drm/nv40/pm: write nv40-specific reclocking routines drm/nv40/pm: parse geometric delta clock from vbios ...
