Merge branch 'drm-core-next' of git://people.freedesktop.org/~airlied/linux
* 'drm-core-next' of git://people.freedesktop.org/~airlied/linux: (307 commits) drm/nouveau/pm: fix build with HWMON off gma500: silence gcc warnings in mid_get_vbt_data() drm/ttm: fix condition (and vs or) drm/radeon: double lock typo in radeon_vm_bo_rmv() drm/radeon: use after free in radeon_vm_bo_add() drm/sis|via: don't return stack garbage from free_mem ioctl drm/radeon/kms: remove pointless CS flags priority struct drm/radeon/kms: check if vm is supported in VA ioctl drm: introduce drm_can_sleep and use in intel/radeon drivers. (v2) radeon: Fix disabling PCI bus mastering on big endian hosts. ttm: fix agp since ttm tt rework agp: Fix multi-line warning message whitespace drm/ttm/dma: Fix accounting error when calling ttm_mem_global_free_page and don't try to free freed pages. drm/ttm/dma: Only call set_pages_array_wb when the page is not in WB pool. drm/radeon/kms: sync across multiple rings when doing bo moves v3 drm/radeon/kms: Add support for multi-ring sync in CS ioctl (v2) drm/radeon: GPU virtual memory support v22 drm: make DRM_UNLOCKED ioctls with their own mutex drm: no need to hold global mutex for static data drm/radeon/benchmark: common modes sweep ignores 640x480@32 ... Fix up trivial conflicts in radeon/evergreen.c and vmwgfx/vmwgfx_kms.c
