2007-10-25	Tighten permissions on some buffer manager ioctls.	Thomas Hellstrom
	Set bo init minor to 0. Add the version function to header.
2007-10-25	Buffer manager:	Thomas Hellstrom
	Implement a version check IOCTL for drivers that don't use drmMMInit from user-space. Remove the minor check from the kernel code. That's really up to the driver. Bump major.

	Change the restriction that non-creators can't change the buffer flags to non-creators can't change EVICT and NO_MOVE flags.
2007-10-17	Bug #12838: Fix lock test client vs. server master race and misplaced closes.	Robert Noland
2007-10-17	Fix a race in the auth test where client prevents server from being master.	Robert Noland
2007-10-17	Bug #11870: FreeBSD hardware lock cleanup fix with multiple opens by a process.	Jung-uk Kim
	Previously, the lock would get released on the first close by the X Server (during AIGLX setup), and the Radeon driver would then hang in initialization due to unexpected failure in DRM calls that required the lock to be held. Based on a patch by Kostik Belousov.
2007-10-17	Only allow creator to change shared buffer mask.	Thomas Hellstrom
2007-10-17	Remove the op ioctl, and replace it with a setuser ioctl.	Thomas Hellstrom
	Remove need for lock for now. May create races when we clean memory areas or on takedown. Needs to be fixed. Really do a validate on buffer creation in order to avoid problems with fixed memory buffers.
2007-10-17	Revert "Replace NO_MOVE/NO_EVICT flags to buffer objects with an ioctl to ↵	Thomas Hellstrom
	set pinning." This reverts cf2d569daca6954d11a796f4d110148ae2e0c827 commit.
2007-10-17	Revert "Copy the important parts of object_validate into object_create()."	Thomas Hellstrom
	This reverts f9c27aa50b715a7d21858f1ce9e4785120bd0c36 commit.
2007-10-17	Revert "Remove the pinned buffer from the LRU when pinning."	Thomas Hellstrom
	This reverts 3a0bc518e35c62bb9c64c9105f836584d949653f commit.
2007-10-17	Revert "Add some more verbosity to drm_bo_set_pin_req comments."	Thomas Hellstrom
	This reverts e7bfeb3031374653f7e55d67cc1b5c823849359f commit.
2007-10-17	Fix a crash on X startup	Alan Hourihane
2007-10-17	i915: lock struct mutex about buffer object lookups	Dave Airlie
2007-10-16	Merge branch 'master' of git+ssh://git.freedesktop.org/git/mesa/drm into ↵	Alan Hourihane
	modesetting-101 Conflicts: linux-core/drm_bo.c linux-core/drm_objects.h shared-core/i915_dma.c shared-core/i915_drv.h
2007-10-16	Revert part of earlier commit that caused an unresolved symbol for i915.	Michel Dänzer
2007-10-16	drm: drop drm bo list handling code	Dave Airlie
2007-10-16	drm: rename drmBOUnReference to drmBOUnreference for consistency	Dave Airlie
2007-10-16	Drop destroy ioctls for fences and buffer objects.	Kristian Høgsberg
	We now always create a drm_ref_object for user objects and this is then the only things that holds a reference to the user object. This way unreference on will destroy the user object when the last drm_ref_object goes way.
2007-10-16	Take bo type argument out of the ioctl interface.	Kristian Høgsberg
	The buffer object type is still tracked internally, but it is no longer part of the user space visible ioctl interface. If the bo create ioctl specifies a non-NULL buffer address we assume drm_bo_type_user, otherwise drm_bo_type_dc. Kernel side allocations call drm_buffer_object_create() directly and can still specify drm_bo_type_kernel. Not 100% this makes sense either, but with this patch, the buffer type is no longer exported and we can clean up the internals later on.
2007-10-16	Eliminate support for fake buffers.	[utf-8] Kristian Høgsberg
2007-10-16	nouveau: revert unintended change.	Ben Skeggs
