Merge branch 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6
* 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (24 commits)
agp/intel: Make intel_i965_mask_memory use dma_addr_t for physical addresses
agp: add user mapping support to ATI AGP bridge.
drm/i915: enable GEM on PAE.
drm/radeon: fix unused variables warning
agp: switch AGP to use page array instead of unsigned long array
agpgart: detected ALi M???? chipset with M1621
drm/radeon: command stream checker for r3xx-r5xx hardware
drm/radeon: Fully initialize LVDS info also when we can't get it from the ROM.
radeon: Fix CP byte order on big endian architectures with KMS.
agp/uninorth: Handle user memory types.
drm/ttm: Add some powerpc cache flush code.
radeon: Enable modesetting on non-x86.
drm/radeon: Respect AGP cant_use_aperture flag.
drm: EDID endianness fixes.
drm/radeon: this VRAM vs aperture test is wrong, just remove it.
drm/ttm: fix an error path to exit function correctly
drm: Apply "Memory fragmentation from lost alignment blocks"
ttm: Return -ERESTART when a signal interrupts bo eviction.
drm: Remove memory debugging infrastructure.
drm/i915: Clear fence register on tiling stride change.
