Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
A couple of bios parser fixes (one for ancient chips, another for new ones - important in Optimus configs). Another to make sure KMS is enabled on certain Optimus configs, and a TTM failure path fix.
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/ttm: prevent double-free in nouveau_sgdma_create_ttm() failure path
drm/nouveau/bios/init: fix thinko in INIT_CONFIGURE_MEM
drm/nouveau/kms: enable for non-vga pci classes
drm/nouveau/bios/init: stub opcode 0xaa
